Rebuild utilities are not supported on APFS. I presume these should be ok with APFS. Additionally, DiskWarrior finds issues in HFS+ that macOS including Disk Utilitys First Aid do not see.

So why keep looking for one? And if you read the penultimate paragraph of the article, I clearly state: https://www.stellarinfo.com/blog/how-to- Is "rebuilding" with Disk Warrior and "repairing" with Disk Utility the same? https://www.micromat.com/component/kunen Alsoft (DriveWarrior) is completely misleading and wrong: Using DiskWarrior 5.2 while started (booted) from High Sierra or Mojave. This cant of course guarantee that errors never occur in an APFS file system, but should eliminate this process of steady degradation and eliminate the need for such routine maintenance. Typically only takes a bit of time, but may not be necessary now. https://docs.oracle.com/cd/E19455-01/805. yesterdayJul 28, 2022 by You are using an out of date browser. Howard. Personally, Id like Steve Gibson of GRC to release SpinRite 7 for Mac! Yes, this can happen, I gather, but still isnt the same penalty as with hard disk seeks. The work-around for Big Sur seems to be to do a check on the Media. Recover/rebuild APFS Container Scheme?
This is efficient, but inherently prone to error. Again, that is like routine (whatever that means) humans health checks, even on young people, which are likely being healthy, but some of they will have things to cure. Journalling isnt a solution, as it doesnt prevent those errors from occurring, merely mitigates them when they do occur. Do you mean that the file system will warn all the times when there is a problem with APFS? Im sorry, I have no idea what this possible tracking is. Then, time will tell if it is useful. In doing so, it has also removed any need for periodic maintenance. You are of course not referring there to scientific facts but what are known in the trade as unconfirmed anecdotal reports of file system errors. See if the free Demo allows you to fix the drive. Please help push it! Thank you. As I have explained, I thought quite explicitly, APFS is specifically designed to prevent those from occurring. I think her data is corrupt, because i've moved the drive to multiple MacBooks and get the same error. I still use the app to optimize directories for my HFS+ external drives. Takes only a second and then eureka, the check proceeds. Note that Tech Tool Pro works fine with the APFS format. I'm thinking they will drop it in the too-hard basket. BTW i thought the RIGHT TO REPAIR movement already succeeded with new laws that will require manufactures to create innovative products that are mod like repairable (hard drives, cameras, memory upgrades etc) no? I assume you have to manually compare and decide which version to keep (source or destination). A common problem encountered when trying to check volumes or their containers is that Disk Utility returns an immediate error, reporting that item couldnt be checked because the volume couldnt be unmounted. As a result, in common with most file systems designed for hard disks, it defaults to overwriting data when changing it, notably in the file system metadata. Do keep in mind SSD drives can encounter issues that cant be fixed as unlike a spinning disk which has tracks and sectors that can get messed up they use direct block access. I still wonder whether I should have left them HFS+. And there are typos again that I only notice after posting. Wow! I agree - was a paying client of DW for many years - but I don't see any benefit to buy it again - never really saw any value in the past - what does it really do? There is a lot of confusion in this topic. I suppose this must make sense to him. The open source Mailtrackerblocker Mail add-on is suggesting you are! They're at the mercy of Apple who was slow to release the documentation they needed to write APFS compatible DiskWarrior. I am now using Open Core EFI boot and it is running Big Sur nicely.
I think you need to splash some cold water on your face ;-}. However, Tech Tool Pro is the. It's a slower process than DiskWarrior but at least it's capable of doing the job. Given the three existing types of link/alias, I have quite enough to choose from (and mess up!). From where Im sitting, while theres always room for improvement in features, APFS does its job excellently.
Im great with backups of my SSD, but this was a fairly new drive where Id recently put lots of personal files that I hadnt yet backed up anywhere else The drive was partitioned into 2 volumes, APFS and HFS+ for time machine. I am still waiting for DiskWarrior 6 to do it with APFS disks. I use a few of these apps and I don't need be online to use them.
I can report, though, that synthetic firmlinks on APFS are kinda broken. ; and ii) if the answer is that DiskWarrior 6 will be released for sure with 100% confidence (which would mean that Alsoft has all the required documentation to do it), should we expect it this year, next year, or in which timeframe (even if widely or wildly approximate; for instance, in five years, or whatever)? Please check CCCs excellent documentation if you have further interest in this. Alsoft has mentioned on their website that they will be releasing DiskWarrior v.5.3, which will essentially be their M1-compatible version of v.5.2. ), because in HFS+ the system did not warn about them; and ii) if DiskWarrior will be able to fix the APFS issues that Disk Utilitys First Aid cannot fix, as happened with HFS+. Howard. Thats why its important to keep the pressure on! It will still only rebuild HFS+ disks but there is no ETA / schedule mentioned. I then ran First Aid on it which I deeply regret. Luckily, I saw it.
Will there come a time when this overhead is noticeable, or at least measurable? This article considers where APFS is today in Big Sur, which has now reached version 1677.81.1. But even the former is not bullet-proof. I think that it may be some years before well have third-party APFS repair tools which are superior to fsck_apfs. I would be happy then. Press Esc to cancel. The files current checksum does not match the expected recorded checksum. APFS formatting. The HFS+ partition seems fine. IT IS IMPORTANT TO SEND FEEDBACK TO APPLE SO THAT THEY RELEASE DOCUMENTATION ABOUT HOW TO WRITE TO APFS DISKS AS THEY HAVE DONE ABOUT HOW TO READ THEM. Hopefully, the day will come (soon) that Apple releases complete documentation of the APFS file system so developers and the rest of us can get on with our lives. Diskwarrior 5.2 recognises APFS drives but cant repair them just yet. While MFS was designed for use with 400 KB floppy disks and couldnt cope with storage larger than 20 MB, HFS+ was intended for hard disks larger than any currently available. Hence are not as efficient and safe as if the filesystem contained them natively and runs checksumming all time. What does Disk First Aid do? Not surprised at the criminal monopoly, conspiracy theorist have also gone as far as alleging Jobs was assassinated by the government who has been in the backseat of Apple since the hiring of ex Cyber Security from NSA which kind of does match the whistle blowers info out there about the domestic spying abuses against citizens including the current president for personal gain or investment interests carried out by agencies with zero over sight from DOJ or the office of the inspectors General. It does not happen with HFS+, and as said, many times DiskWarrior finds issues in HFS+ that macOS including Disk Utilitys First Aid do not see. Its impressive that your scan of several terabytes showed no errors, but if any bits within the files had gotten flipped, would you have any way to notice, until you opened the file and it looked funny? If the file system warns when there is a problem, that would be great and enough.

Just is case there is some issue, to fix it as soon as possible once it arises. Howard. It sounds like you need one of each ;-}, This is not a political blog and we really don't like slamming people no matter who they are. Howard. But says part of the truth in the small print: **Note:Optimization for APFS rotational drives is not yet possible with the current amount of APFS documentation provided by Apple, which currently provides insufficieant documentation for defragmenting a disk. So please let's not travel down this path. I wish First Aid would recommend I backup the drive before wrecking it. No utility can fully support APFS at the moment, both because APFS is itself a work-in-progress, and Apple has yet to release documentation for it for developers. For Big Sur, Apple advises users to check from the bottom up, starting with APFS volumes, then containers, and finally disks. Frank Kistner, 2022 iFixit Licensed under Creative Commons Privacy In the current version of Disk Utility, that isnt all necessary, as checking a container will normally result in each of its volumes also being checked, together with any snapshots. Sorry they are literally nothing whatsoever to do with me, but WordPress. Understand. In relation to Stellar Data Recovery Professional, it does not repair disks; it recovers files from them. Checksums are not retroactively computed for files that were copied by earlier releases of OS X. Howard. a firmlink of /mnt and /private/mnt. Thus, probably the best approach is to keep on performing routine checks on APFSs health, but instead of at least once a month (as now Alsoft recommends about DiskWarrior for HFS+ disks), maybe once every six months or a year, or whatever, but sometimes; not never ever. The need for this reduced substantially with journalling, but it was a workaround rather than a full solution, and directory maintenance remained popular. They have yet to deliver. I do like the shared Volume feature, which makes disk management flexible. Sometimes, unexpected issues arise. HOWEVER, if this occurred IMMEDIATELY following an attempt to install Catalina chances are the install and accompanying restructuring of the drive went sideways and you will probably never get it to run correctly again without reinitializing the drive (APFS) and doing a clean reinstall of the OS. Howard. In other words, will it be faster to access a contiguous file as opposed to a file with 1,000 (or X) extents when no seeking is done? Techtool Pro can also repair Apple's new APFS file system, standard Mac OS Extended volumes, as well as MS-DOS (FAT32) and ExFAT formatted volumes. I wasn't clear enough, sorry. In addition to native Mac drive formats, Mac OS Extended and APFS, Techtool Pro supports testing and repair ofMS-DOS (FAT32) and ExFAT formatted volumes. You must log in or register to reply here. Checking and repairing a volume doesnt detect such data errors, neither can it fix them. Yes, weve covered this with respect to TM backups previously. As those errors dont appear to occur in APFS, because it has been designed to prevent them, what purpose could routine use of DiskWarrior for APFS serve which cant already be catered for by Disk Utility and the tool which it uses, fsck_apfs? We have been waiting for it since 2017 (almost four years ago!) That's good, as Big Sur is still not stable enough yet, even with V11.1 due to arrive soon. Howard. The vexing part has been the noted issue of the insistence that First Aid cant proceed because the disk is mounted (of course it is). In addition to comparing metadata (filename, filesize, timestamps) between source and destination to get certainty that this is the same file, it also does a checksum (hence needs a full read of all content on source and destination). * Formatting, mounting, un-mounting, and ejecting disks. Ugh.
In short, TechTool Pro can repair (not rebuild) APFS disks, and for the former it just uses fsck, as Disk Utility does. Sadly, it seems WP has joined the ranks of FB, Google, LinkedIn, etc., with its pernicious spying. To assess its success, I have surveyed all the storage accessed by my iMac Pro, looking for errors. Everything that I see here appears highly ethical, which is one of the reasons that I keep with WordPress and Automattic. If I could ask Rusty Little two questions (he has posted in this site before), they would be: i) are you sure that Alsoft will eventually release DiskWarrior 6 to rebuild the directory of APFS disks, or is that a guess that may or may not happen? But regardless if any of this is true or really spread miss information to smear america its just shows the lack of trust people have with Apple and all these sketchy data recovery apps that require you to be online to use them. I think the examples you are quoting are actually in the man page for synthetic.conf, which hasnt been updated for well over a year. All you're seeing here is a company that under big Tim has become more aggressive in hiding its code and limiting equipment service to its self. Theyve had three and a half years to get into gear. Very informative. Does DFA rebuild the corrupt directory? But sometimes beginners are luckier. HFS+, which APFS has all but replaced, was the successor to HFS, which in turn replaced the Macs original MFS in 1985. Similar? What you are seeing is the seeds of our efforts sprouting! So you do still think that you need to perform regular maintenance checks on the file system in current releases of APFS? When I checked It, I noticed several folders were missing. Yes, your hard disks shouldnt suffer with APFS. DiskWarrior resolves existing disk damage by rebuilding your HFS+ disk directory, doesn't work on APFS volumes yet. Because its primarily designed for use with SSDs, for which seek times and fragmentation arent a concern, what APFS does is to write changed metadata to a new location on disk, and only when that has been completed successfully is the original metadata released for re-use, a process known as copy-on-write. Thank you. Much as what happens with mutations, which may accumulate, leading to cancer. There are more than 100 snapshots, made by both Time Machine and Carbon Copy Cloner, and those disks have been running Catalina then Big Sur over the past year. Of course companies will go the direction most profitable, but im just saying that T$m Cr00k will and has openly ventured into illegal areas that have not yet been addressed by our US or international courts . Disk Warrior is much better and efficient repairing damaged disks than Disk Utility, because only the former rebuilds from scratch the directory of HFS+ disks. BTW, this system has an updated RX-580 and WiFi BLE card. i'm in need of something much sooner to repair the data on the disk for our customer, this is the error message I'm getting when trying to perform FSCK or first aid on the disk, "macbook first aid volume could not be verified completely". So when you want to create a root directory, lets say /mnt, you should not follow Apples example #2 and firmlink /mnt and /System/Volumes/Data/mnt, because it might lead to a severely impaired experience, but you have to use an already existing location, i.e. Thank you. You said its primarily designed for use with SSDs, for which seek times and fragmentation arent a concern. Some developers are clear about it in their web pages, like Prosoft Engineering: Drive Genius 5. Continuing to improve fsck_apfs and Disk Utility is unglamorous but vital for users, and there will always be scope for third-party alternatives, which Apple should encourage. The next major release of DiskWarrior (DiskWarrior 6.0) will include the ability to rebuild APFS disks. https://www.alsoft.com/DiskWarrior/mojav That is FALSE. Terms So in short, you dont believe a word of this article? File systems do incur errors, and excellent tools for the checking and repair of APFS are among the most important utilities in macOS. Just run it and check Activity Monitor to see which process is running. The movement is alive and well but it needs bodies behind it screaming at the local and regional politicians to alter the laws of the land. I had the drive plugged in my new MacBook and all of a sudden I got a message saying the drive kept disconnecting, which I thought was strange, since that didnt seem to be the case. New EU rules that could mark the end of 'throwaway culture' and e-waste will force tech companies including Apple and Samsung to make products that last longer and are easy to repair. He is a pro at it, for example, while with Jobs he was the one flying to China visiting child slave factories and arranging shipments of 3,4 quarter batches of devices to contain toxic cheap parts assembled by child slave factories., more cuts more profits and its true, Apple has been fined over and over and they dont mind paying the fines as Mr$ Crook has learned that paying the fines is also more profitable then recalls, paying class action law suites off etc cause Apple makes $350 million an hour from all this itself.
As the old saying goes, thats what backups are for, isnt it? Issues are reported using the following legend: ! I do not know the answer to both questions, but searching Internet for, DiskWarrior APFS The RX-580 also support hardware enabled media codecs. DiskWarrior 5.3 to rebuild the directory of HFS+ as native application on ARM-based Apple Silicon Macs was announced to be released soon on November 2020. First rolled out in a bold and daring move on 27 March 2017 to unsuspecting iOS users, weve been running it on our Macs since upgrading to High Sierra in September 2017. Greg Patt, @Greg Patt - It fixes disk corruption issues. While the post linked below does not mention rebuilding the directory of an APFS drive, it does say you can use Apples Disk Utility to repair them. Thus, they are completely different applications. DiskWarrior was a valuable tool for all Mac users prior to the introduction of journalling in HFS+. Thanks in advance! My Mac Pro 5,1 (the old tower) has several SSDs on them including a PCiE M2 system disk, but it also houses some large spinner (4, 6, & 10TB.) Those arent file system errors, and the subject of a whole series of articles here, on data integrity. After First Aid, which ran for a few minutes before quitting and telling me it failed, and recommending I backup the drive, it no longer mounts, and its name even has disappeared. First aid did report errors with it but didnt fail the process and in any case I had no problems with that partition. All you've seen is the dialog and proposed laws, nothing has been made the law of the land. That includes DiskWarrior (Alsoft), TechTool Pro (Micromat) and Drive Genius (Prosoft Engineering). Someone has some insider information? Although, you could still repair all your HFS+ formatted drives and that is something that wouldnt really be difficult even in an APFS formatted Mac. Howard. Thats why we are fighting hard for the Right to Repair. Without breaking the NDA that they have with Apple, of course. Search the Internet for horror stories about it. Our developers are now using this documentation to update DiskWarrior in order to safely rebuild Apple File System (APFS) disks. And lastly find all of your cloning apps and throw them all away! I think you should wait a until they come up with a newer version of their App, otherwise you will have to find other alternatives (which may be great, even perfect but not as perfect as DW). APFS Partitions corrupted Should anything go wrong while changing file system data, such as a crash or even worse a kernel panic, thats likely to leave the file system metadata with a mixture of the old and new, resulting in an error. If so, what error messages did you receive, if any? Alsoft should not do it!!! The onus is on those who feel such maintenance utilities are necessary to provide objective evidence of any shortcomings in APFS which they feel such maintenance might address. Howard. Thank you. Currently, no utility can rebuild the directory of APFS disks on Mac. This FSEvents behavior also occurs without firmlinks, namely when you modify, create or delete a file directly in the root of /System/Volumes/Data, possibly because FSEvents reports / instead, which is really not your current path. Dane Russell Fjelstad, Ali Sadykov I get no feedback at all from those who subscribed to emails, other than the total number. I tried reinstalling DiskWarrior, but the problem remains. You have not a shred of evidence that these are anything like the cumulative errors to which HFS+ is known to be prone, have you? I'd like to repair the data, because if I send her a new install of OS-X, then she moves her data over, we'll have the same issue again. Thanks.
The files recorded checksum is invalid. They need to run extra and as oneshot actions. Customers deserve the truth! Apple has recently released the APFS format documentation. Will that not happen with APFS? It would detect if source and destination dont match. File systems do incur errors, and excellent tools for the checking and repair of APFS are among the most important utilities in macOS. It doesnt tell you whether any file on your Mac is intact or corrupt. How it resolves the conflict, I do not know. I have a screenshot of the message from MailBlocker if you want to see it. But if you activate it you can set it to: Every time the task runs | Once a week | Once a month. JavaScript is disabled. Howard, are you using a mail tracker in emails? I do not know. (On my system, Finder actually managed to refresh a window in such a unique synthetically firmlinked path, but a developer whom I notified wasnt as lucky; tests with another file manager werent successful either.) https://www.prosofteng.com/drive-genius- TechTool Pro. Thanks. one thats already hard-firmlinked by default system rules, e.g. Disc Warrior 6.0 is *still* unavailable! It may not display this or other websites correctly.
No output is generated for matching checksums. Howard. Chances are that most checks will return no issue, but a few may identify issues that can then be fixed, preventing further damage. Youll want to create a bootable external drive to run it from or setup a BootWell drive. After all, thats how its intended to work, just like any other part of macOS. Apple addressed this by introducing journalling, in which the file system makes each change first in a record in its journal, then to the catalogue in the file system metadata. SO, THE CONCLUSION IS THAT SOME DEVELOPERS ARE NOT TELLING THE PLAIN TRUTH, BUT AT LEAST ONE IS. TechTool Pro web page is confusing about it and actually misleading if you do not read with extreme care, but Micromat explains it clearly in their knowledge base documentation and forum. One thing Ive often wondered about SSD-based filesystems is that although seeking as a result of fragmentation no longer happens, the number of extents (or whatever the filesystem calls them) will continue to increase. /bar instead of /System/Volumes/Data/barthe latter is the actual path, the former is just the firmlink, so when you modify, create or delete files in that *unique* synthetically linked root path, GUI file managers often (if not always) dont receive any correct path, so the contents of the current window or tab arent refreshed. If this was an HFS+ volume, I bet first aid couldve fixed it. I'f possible format the test drive HFS+ so you can then use the better tools. I understand your anger and frustration.
Looking forward to DiskWarrior 6 (hopefully, within three to six months, as they said in Twitter), which will rebuild the directory of APFS disks. https://www.dailymail.co.uk/sciencetech/ https://www.ecologique-solidaire.gouv.fr No Right to Repair here in the US is still not locked in and even the EU its not. You can check out the interesting article and comments at. Begin typing your search above and press return to search. IF I understand what Steve Gibson says about the new Spinrite 6.1 and the coming 7, it will detect degraded write (read?) with Google shows people reporting serious problems with APFS that Disk Utilitys First Aid cannot repair. That includes DiskWarrior (the best in the repair arsenal), TechTool Pro (second choice) and Drive Genius (third choice). As Apples fsck_apfs is written by the engineers that developed the file system, and they now have several years experience at repairing it in macOS, I suspect it will be a good while (years) before any third party tool is a match for it. Thank you. Pretty slack. Because they do arise. Howard. I appreciate the info and your expertise. I only wonder: i) if macOS will warn of issues when they arise in APFS (because sometimes they do arise, for whatever reason, including idiot user behavior! Howard. Catalina, together with the APFS file structure, has been a NIGHTMARE. If you dont like what it does, please unsubscribe to them and use the ample RSS feeds instead. Apple should not do that!!! The main one is Rusty Little (Project Manager). Why cant you leave it to the file system to tell you when theres a problem? APFS is proving to be a fine filesystem, but it (rather infamously) only checksums metadata, not file contents. Dane Russell Fjelstad. Thank you. @Tim I too would love if APFS would feature checksumming on file content not only metadata. Theyve had three and a half years to get into gear. It is good to have both and use them depending on the issue to address (repair disks or recover files). In any case, the fact is that some people are finding serious problems with APFS that Disk Utilitys First Aid cannot repair. Howard. The best is to repair disks, but if that is not possible, the second can help to recover files to other disk (the damaged disk will continue being damaged with such second approach). Normally it was sufficient to repeat the request, which was then successful. Once you get the drive fixed make a backup and then either run the defragment tool or reformat the drive and install a fresh OS onto it then recover your data from the backup (TimeMachine) being the better one. Apps including the Finder then should report that to the user thats not the job of macOS within an app. Carbon Copy Cloner (CCC) and also the command line version of TimeMachine (tmutil) have checksumming / comparison features. I expect it will be less needed than with HFS+, since APFS is more robust, but still will be a life-saver when issues arise with APFS. It's running the most up to date version of Mojave. now I cant use it. Without those cumulative minor errors, theres no evidence that APFS suffers from that problem. However, APFS does appear to have achieved its objective of eliminating the routine accumulation of file system errors to which HFS+ was prone. The problem may arise when you do not check it and eventually issues accumulate over months or years, reaching the point a a major problem. Dec 29, 2019 by We would need a scientific report with many cases and scenarios to reach appropriate conclusions. Id love to know what you think that might do with APFS on SSDs. Prior to its introduction, it was common for most crashes to result in at least minor damage to file system metadata, and many of us routinely rebuilt its directories after each crash, or as periodic maintenance, to prevent those accumulating until serious errors resulted. Among the problems with hard disk storage which HFS+ tried to address were seek times, fragmentation, and limited space. But you are not out of options! it's a 1 month old seagate firecuda 1 TB SSHD. I assume that you have run Disk Utility from an external drive, the restore partition (command-R boot) or an internet boot (command-option-R)? I think that copy-on-write for file system metadata is still an advantage to them in terms of reducing disk errors, so perhaps converting them wasnt a bad idea. Use TimeMachine to create a backup and then restore to a fresh drive to double check to see if the corruption is resolved.
This is efficient, but inherently prone to error. Again, that is like routine (whatever that means) humans health checks, even on young people, which are likely being healthy, but some of they will have things to cure. Journalling isnt a solution, as it doesnt prevent those errors from occurring, merely mitigates them when they do occur.

It does not happen with HFS+, and as said, many times DiskWarrior finds issues in HFS+ that macOS including Disk Utilitys First Aid do not see. Its impressive that your scan of several terabytes showed no errors, but if any bits within the files had gotten flipped, would you have any way to notice, until you opened the file and it looked funny? If the file system warns when there is a problem, that would be great and enough.

Just is case there is some issue, to fix it as soon as possible once it arises. Howard. It sounds like you need one of each ;-}, This is not a political blog and we really don't like slamming people no matter who they are. Howard. But says part of the truth in the small print: **Note:Optimization for APFS rotational drives is not yet possible with the current amount of APFS documentation provided by Apple, which currently provides insufficieant documentation for defragmenting a disk. So please let's not travel down this path. I wish First Aid would recommend I backup the drive before wrecking it. No utility can fully support APFS at the moment, both because APFS is itself a work-in-progress, and Apple has yet to release documentation for it for developers. For Big Sur, Apple advises users to check from the bottom up, starting with APFS volumes, then containers, and finally disks. Frank Kistner, 2022 iFixit Licensed under Creative Commons Privacy In the current version of Disk Utility, that isnt all necessary, as checking a container will normally result in each of its volumes also being checked, together with any snapshots. Sorry they are literally nothing whatsoever to do with me, but WordPress. Understand. In relation to Stellar Data Recovery Professional, it does not repair disks; it recovers files from them. Checksums are not retroactively computed for files that were copied by earlier releases of OS X. Howard. a firmlink of /mnt and /private/mnt. Thus, probably the best approach is to keep on performing routine checks on APFSs health, but instead of at least once a month (as now Alsoft recommends about DiskWarrior for HFS+ disks), maybe once every six months or a year, or whatever, but sometimes; not never ever. The need for this reduced substantially with journalling, but it was a workaround rather than a full solution, and directory maintenance remained popular. They have yet to deliver. I do like the shared Volume feature, which makes disk management flexible. Sometimes, unexpected issues arise. HOWEVER, if this occurred IMMEDIATELY following an attempt to install Catalina chances are the install and accompanying restructuring of the drive went sideways and you will probably never get it to run correctly again without reinitializing the drive (APFS) and doing a clean reinstall of the OS. Howard. In other words, will it be faster to access a contiguous file as opposed to a file with 1,000 (or X) extents when no seeking is done? Techtool Pro can also repair Apple's new APFS file system, standard Mac OS Extended volumes, as well as MS-DOS (FAT32) and ExFAT formatted volumes. I wasn't clear enough, sorry. In addition to native Mac drive formats, Mac OS Extended and APFS, Techtool Pro supports testing and repair ofMS-DOS (FAT32) and ExFAT formatted volumes. You must log in or register to reply here. Checking and repairing a volume doesnt detect such data errors, neither can it fix them. Yes, weve covered this with respect to TM backups previously. As those errors dont appear to occur in APFS, because it has been designed to prevent them, what purpose could routine use of DiskWarrior for APFS serve which cant already be catered for by Disk Utility and the tool which it uses, fsck_apfs? We have been waiting for it since 2017 (almost four years ago!) That's good, as Big Sur is still not stable enough yet, even with V11.1 due to arrive soon. Howard. The vexing part has been the noted issue of the insistence that First Aid cant proceed because the disk is mounted (of course it is). In addition to comparing metadata (filename, filesize, timestamps) between source and destination to get certainty that this is the same file, it also does a checksum (hence needs a full read of all content on source and destination). * Formatting, mounting, un-mounting, and ejecting disks. Ugh.
In short, TechTool Pro can repair (not rebuild) APFS disks, and for the former it just uses fsck, as Disk Utility does. Sadly, it seems WP has joined the ranks of FB, Google, LinkedIn, etc., with its pernicious spying. To assess its success, I have surveyed all the storage accessed by my iMac Pro, looking for errors. Everything that I see here appears highly ethical, which is one of the reasons that I keep with WordPress and Automattic. If I could ask Rusty Little two questions (he has posted in this site before), they would be: i) are you sure that Alsoft will eventually release DiskWarrior 6 to rebuild the directory of APFS disks, or is that a guess that may or may not happen? But regardless if any of this is true or really spread miss information to smear america its just shows the lack of trust people have with Apple and all these sketchy data recovery apps that require you to be online to use them. I think the examples you are quoting are actually in the man page for synthetic.conf, which hasnt been updated for well over a year. All you're seeing here is a company that under big Tim has become more aggressive in hiding its code and limiting equipment service to its self. Theyve had three and a half years to get into gear. Very informative. Does DFA rebuild the corrupt directory? But sometimes beginners are luckier. HFS+, which APFS has all but replaced, was the successor to HFS, which in turn replaced the Macs original MFS in 1985. Similar? What you are seeing is the seeds of our efforts sprouting! So you do still think that you need to perform regular maintenance checks on the file system in current releases of APFS? When I checked It, I noticed several folders were missing. Yes, your hard disks shouldnt suffer with APFS. DiskWarrior resolves existing disk damage by rebuilding your HFS+ disk directory, doesn't work on APFS volumes yet. Because its primarily designed for use with SSDs, for which seek times and fragmentation arent a concern, what APFS does is to write changed metadata to a new location on disk, and only when that has been completed successfully is the original metadata released for re-use, a process known as copy-on-write. Thank you. Much as what happens with mutations, which may accumulate, leading to cancer. There are more than 100 snapshots, made by both Time Machine and Carbon Copy Cloner, and those disks have been running Catalina then Big Sur over the past year. Of course companies will go the direction most profitable, but im just saying that T$m Cr00k will and has openly ventured into illegal areas that have not yet been addressed by our US or international courts . Disk Warrior is much better and efficient repairing damaged disks than Disk Utility, because only the former rebuilds from scratch the directory of HFS+ disks. BTW, this system has an updated RX-580 and WiFi BLE card. i'm in need of something much sooner to repair the data on the disk for our customer, this is the error message I'm getting when trying to perform FSCK or first aid on the disk, "macbook first aid volume could not be verified completely". So when you want to create a root directory, lets say /mnt, you should not follow Apples example #2 and firmlink /mnt and /System/Volumes/Data/mnt, because it might lead to a severely impaired experience, but you have to use an already existing location, i.e. Thank you. You said its primarily designed for use with SSDs, for which seek times and fragmentation arent a concern. Some developers are clear about it in their web pages, like Prosoft Engineering: Drive Genius 5. Continuing to improve fsck_apfs and Disk Utility is unglamorous but vital for users, and there will always be scope for third-party alternatives, which Apple should encourage. The next major release of DiskWarrior (DiskWarrior 6.0) will include the ability to rebuild APFS disks. https://www.alsoft.com/DiskWarrior/mojav That is FALSE. Terms So in short, you dont believe a word of this article? File systems do incur errors, and excellent tools for the checking and repair of APFS are among the most important utilities in macOS. Just run it and check Activity Monitor to see which process is running. The movement is alive and well but it needs bodies behind it screaming at the local and regional politicians to alter the laws of the land. I had the drive plugged in my new MacBook and all of a sudden I got a message saying the drive kept disconnecting, which I thought was strange, since that didnt seem to be the case. New EU rules that could mark the end of 'throwaway culture' and e-waste will force tech companies including Apple and Samsung to make products that last longer and are easy to repair. He is a pro at it, for example, while with Jobs he was the one flying to China visiting child slave factories and arranging shipments of 3,4 quarter batches of devices to contain toxic cheap parts assembled by child slave factories., more cuts more profits and its true, Apple has been fined over and over and they dont mind paying the fines as Mr$ Crook has learned that paying the fines is also more profitable then recalls, paying class action law suites off etc cause Apple makes $350 million an hour from all this itself.
As the old saying goes, thats what backups are for, isnt it? Issues are reported using the following legend: ! I do not know the answer to both questions, but searching Internet for, DiskWarrior APFS The RX-580 also support hardware enabled media codecs. DiskWarrior 5.3 to rebuild the directory of HFS+ as native application on ARM-based Apple Silicon Macs was announced to be released soon on November 2020. First rolled out in a bold and daring move on 27 March 2017 to unsuspecting iOS users, weve been running it on our Macs since upgrading to High Sierra in September 2017. Greg Patt, @Greg Patt - It fixes disk corruption issues. While the post linked below does not mention rebuilding the directory of an APFS drive, it does say you can use Apples Disk Utility to repair them. Thus, they are completely different applications. DiskWarrior was a valuable tool for all Mac users prior to the introduction of journalling in HFS+. Thanks in advance! My Mac Pro 5,1 (the old tower) has several SSDs on them including a PCiE M2 system disk, but it also houses some large spinner (4, 6, & 10TB.) Those arent file system errors, and the subject of a whole series of articles here, on data integrity. After First Aid, which ran for a few minutes before quitting and telling me it failed, and recommending I backup the drive, it no longer mounts, and its name even has disappeared. First aid did report errors with it but didnt fail the process and in any case I had no problems with that partition. All you've seen is the dialog and proposed laws, nothing has been made the law of the land. That includes DiskWarrior (Alsoft), TechTool Pro (Micromat) and Drive Genius (Prosoft Engineering). Someone has some insider information? Although, you could still repair all your HFS+ formatted drives and that is something that wouldnt really be difficult even in an APFS formatted Mac. Howard. Thats why we are fighting hard for the Right to Repair. Without breaking the NDA that they have with Apple, of course. Search the Internet for horror stories about it. Our developers are now using this documentation to update DiskWarrior in order to safely rebuild Apple File System (APFS) disks. And lastly find all of your cloning apps and throw them all away! I think you should wait a until they come up with a newer version of their App, otherwise you will have to find other alternatives (which may be great, even perfect but not as perfect as DW). APFS Partitions corrupted Should anything go wrong while changing file system data, such as a crash or even worse a kernel panic, thats likely to leave the file system metadata with a mixture of the old and new, resulting in an error. If so, what error messages did you receive, if any? Alsoft should not do it!!! The onus is on those who feel such maintenance utilities are necessary to provide objective evidence of any shortcomings in APFS which they feel such maintenance might address. Howard. Thank you. Currently, no utility can rebuild the directory of APFS disks on Mac. This FSEvents behavior also occurs without firmlinks, namely when you modify, create or delete a file directly in the root of /System/Volumes/Data, possibly because FSEvents reports / instead, which is really not your current path. Dane Russell Fjelstad, Ali Sadykov I get no feedback at all from those who subscribed to emails, other than the total number. I tried reinstalling DiskWarrior, but the problem remains. You have not a shred of evidence that these are anything like the cumulative errors to which HFS+ is known to be prone, have you? I'd like to repair the data, because if I send her a new install of OS-X, then she moves her data over, we'll have the same issue again. Thanks.
The files recorded checksum is invalid. They need to run extra and as oneshot actions. Customers deserve the truth! Apple has recently released the APFS format documentation. Will that not happen with APFS? It would detect if source and destination dont match. File systems do incur errors, and excellent tools for the checking and repair of APFS are among the most important utilities in macOS. It doesnt tell you whether any file on your Mac is intact or corrupt. How it resolves the conflict, I do not know. I have a screenshot of the message from MailBlocker if you want to see it. But if you activate it you can set it to: Every time the task runs | Once a week | Once a month. JavaScript is disabled. Howard, are you using a mail tracker in emails? I do not know. (On my system, Finder actually managed to refresh a window in such a unique synthetically firmlinked path, but a developer whom I notified wasnt as lucky; tests with another file manager werent successful either.) https://www.prosofteng.com/drive-genius- TechTool Pro. Thanks. one thats already hard-firmlinked by default system rules, e.g. Disc Warrior 6.0 is *still* unavailable! It may not display this or other websites correctly.
No output is generated for matching checksums. Howard. Chances are that most checks will return no issue, but a few may identify issues that can then be fixed, preventing further damage. Youll want to create a bootable external drive to run it from or setup a BootWell drive. After all, thats how its intended to work, just like any other part of macOS. Apple addressed this by introducing journalling, in which the file system makes each change first in a record in its journal, then to the catalogue in the file system metadata. SO, THE CONCLUSION IS THAT SOME DEVELOPERS ARE NOT TELLING THE PLAIN TRUTH, BUT AT LEAST ONE IS. TechTool Pro web page is confusing about it and actually misleading if you do not read with extreme care, but Micromat explains it clearly in their knowledge base documentation and forum. One thing Ive often wondered about SSD-based filesystems is that although seeking as a result of fragmentation no longer happens, the number of extents (or whatever the filesystem calls them) will continue to increase. /bar instead of /System/Volumes/Data/barthe latter is the actual path, the former is just the firmlink, so when you modify, create or delete files in that *unique* synthetically linked root path, GUI file managers often (if not always) dont receive any correct path, so the contents of the current window or tab arent refreshed. If this was an HFS+ volume, I bet first aid couldve fixed it. I'f possible format the test drive HFS+ so you can then use the better tools. I understand your anger and frustration.
Looking forward to DiskWarrior 6 (hopefully, within three to six months, as they said in Twitter), which will rebuild the directory of APFS disks. https://www.dailymail.co.uk/sciencetech/ https://www.ecologique-solidaire.gouv.fr No Right to Repair here in the US is still not locked in and even the EU its not. You can check out the interesting article and comments at. Begin typing your search above and press return to search. IF I understand what Steve Gibson says about the new Spinrite 6.1 and the coming 7, it will detect degraded write (read?) with Google shows people reporting serious problems with APFS that Disk Utilitys First Aid cannot repair. That includes DiskWarrior (the best in the repair arsenal), TechTool Pro (second choice) and Drive Genius (third choice). As Apples fsck_apfs is written by the engineers that developed the file system, and they now have several years experience at repairing it in macOS, I suspect it will be a good while (years) before any third party tool is a match for it. Thank you. Pretty slack. Because they do arise. Howard. I appreciate the info and your expertise. I only wonder: i) if macOS will warn of issues when they arise in APFS (because sometimes they do arise, for whatever reason, including idiot user behavior! Howard. Catalina, together with the APFS file structure, has been a NIGHTMARE. If you dont like what it does, please unsubscribe to them and use the ample RSS feeds instead. Apple should not do that!!! The main one is Rusty Little (Project Manager). Why cant you leave it to the file system to tell you when theres a problem? APFS is proving to be a fine filesystem, but it (rather infamously) only checksums metadata, not file contents. Dane Russell Fjelstad. Thank you. @Tim I too would love if APFS would feature checksumming on file content not only metadata. Theyve had three and a half years to get into gear. It is good to have both and use them depending on the issue to address (repair disks or recover files). In any case, the fact is that some people are finding serious problems with APFS that Disk Utilitys First Aid cannot repair. Howard. The best is to repair disks, but if that is not possible, the second can help to recover files to other disk (the damaged disk will continue being damaged with such second approach). Normally it was sufficient to repeat the request, which was then successful. Once you get the drive fixed make a backup and then either run the defragment tool or reformat the drive and install a fresh OS onto it then recover your data from the backup (TimeMachine) being the better one. Apps including the Finder then should report that to the user thats not the job of macOS within an app. Carbon Copy Cloner (CCC) and also the command line version of TimeMachine (tmutil) have checksumming / comparison features. I expect it will be less needed than with HFS+, since APFS is more robust, but still will be a life-saver when issues arise with APFS. It's running the most up to date version of Mojave. now I cant use it. Without those cumulative minor errors, theres no evidence that APFS suffers from that problem. However, APFS does appear to have achieved its objective of eliminating the routine accumulation of file system errors to which HFS+ was prone. The problem may arise when you do not check it and eventually issues accumulate over months or years, reaching the point a a major problem. Dec 29, 2019 by We would need a scientific report with many cases and scenarios to reach appropriate conclusions. Id love to know what you think that might do with APFS on SSDs. Prior to its introduction, it was common for most crashes to result in at least minor damage to file system metadata, and many of us routinely rebuilt its directories after each crash, or as periodic maintenance, to prevent those accumulating until serious errors resulted. Among the problems with hard disk storage which HFS+ tried to address were seek times, fragmentation, and limited space. But you are not out of options! it's a 1 month old seagate firecuda 1 TB SSHD. I assume that you have run Disk Utility from an external drive, the restore partition (command-R boot) or an internet boot (command-option-R)? I think that copy-on-write for file system metadata is still an advantage to them in terms of reducing disk errors, so perhaps converting them wasnt a bad idea. Use TimeMachine to create a backup and then restore to a fresh drive to double check to see if the corruption is resolved.
