    Diskwarrior and SSDs
    Given that Diskwarrior doesn't seem to be coming up with a new version which covers SSDs, is there anything similar on the market which will help those of us who think our directories need looking at and tidying up?

    Because Apple has been so stingy until recently about releasing the details concerning APFS, there really isn't a comparable utility like DiskWarrior. Have you read through the latest information from AlSoft?

    DiskWarrior has no problems working with SSD's as long as they are formatted HFS+:
    FAQ — ALSOFT

    As has been mentioned, Apple hasn't released the full specifications for APFS, so NO ONE has been able to create a comprehensive third party hard drive repair utility for recent Macs using APFS (SSD OR rotating disk hard drive).

    However, this may all be mostly moot. On a different discussion list for consultants it was noted that in recent years Apple's included Disk Utility/First Aid has become quite competent, and that very few folks ever need to resort to Disk Warrior anymore.

    And in those very few instances where First Aid has failed and Disk Warrior seems warranted, Disk Warrior may still not be the best choice. You see, Disk Warrior is now $120. For $120 (or less) you can usually purchase a brand new replacement hard drive and clone your backup onto it, which is a better option than using Disk Warrior, because even though Disk Warrior may repair your damaged hard drive, once it has become so damaged that Disk Warrior was necessary to repair it, that drive becomes suspect with regard to its reliability.

    I used to hear from folks all the time who needed and used Disk Warrior, and Disk Warrior pulled off a miraculous feat by resurrecting their hard drive. But those reports stopped years ago. I think that, at this point, Disk Warrior is an anachronism. Indeed, one of the very reasons for the existence of APFS is to ensure the integrity of your data more effectively than the outdated HFS+. APFS may sound the death kneel for Disk Warrior.

    Interesting, I too am of the opinion that Disk Utility First Aid has improved markedly of late. Shane run on Catalina it now effectively unmounts the Macintosh HD completely. The background goes blank and the desktop image disappears. Much like running from the Recovery partition. I am now wondering if there is any difference between the two methods. In the past the general opinion seemed to be for Disk Utility First Aid to be truly effective one needed to boot from Recovery and run it from there.

    After upgrading my Apple laptops to Catalina, I did TM backups to 4 EHD (duplicate), all seemed to work but took a LONG time (checked a few and still on +HFS, as expected w/ TM) - however, the 4 spinner HDs for CCC (Carbon Copy Cloner) were another question, i.e. conversion from +HFS to APFS was the the first step, then copying, verification, and cache updating - 2 HDs (one for each laptop) did fine BUT the process was LONG (like 3 hrs), not unexpected; however, 2 HDs 'failed' CCC attempt to convert to APFS - I was able to reformat each w/ Disk Utility, but before using the reformatted spinners, I tried my new 1TB Samsung SSD T5 - NO GO! The SSD could only be formatted to +HFS - went to the Samsung community and found a LOT of '*****ing' about this issue w/ their SSD T5s - I'm assuming that Samsung can/will/maybe come up w/ a firmware update to these SSDs so that APFS can be used - if/when Apple decides to revamp TM to run on their newer disc format, my Samsung SSDs will be useless for those purposes, I guess?

    I used to keep Disk Warrior around for those situations where DU couldn't fix a problem. It was first recommended to me by a friend when my wife was bitten by an issue where putting her clamshell iBook to sleep resulted in enough directory damage that DU couldn't fix things.

    Like most of you, I dropped DW quite some time ago. As others have mentioned, the drop in hard drive prices coupled with improvements in DU and other utilities rendered DW of little value. The final blow was when I updated one year and when the next update came out I realized I hadn't used DW once.

    Well, that's news to my Samsung T5 as it converted very easily to APFS using Disk Utility. As a matter of fact, I'm booting Catalina from it and it's fast and works well. How did you try converting it? Did you use Disk Utility?

    Fascinating. I suppose I saw running DiskWarrior every six months as preventive maintenance; I shall rethink that strategy, thanks.

    HMMM - that's odd Charlie - the manual indicates only +HFS (as an Apple option) and in Disk Utility, I was not offered APFS - did you apply a firmware upgrade? I left a post in the Samsung community and will await any replies (not w/ much hope) - also, we drove to the coast today for 5 days and will not return until Friday - the SSD T5 is at home - I'll do some more exploring when I get back. Thanks for the comment. In the meantime, I'll let the ocean soothe my woes - Dave

    No firmware update was applied to the Samsung T5. It came from the factory formatted to NTFS and I erased it with Disk Utility and then formatted it to APFS. No problem whatsoever.

    I also have a LaCie drive which I use for CCC backups but formatted that to HFS+ from the original NTFS. I don't understand why your Samsung T5 would not format to APFS, it should have.

    I also was not offered the APFS option. I solved it by clicking on View and selected Show All Devices. View is in the top left corner of Disk Utility.

    Ah, that explains it. Show All Devices shows the hardware, not just the volumes. So you need that view to get to where the hardware is formatted APFS.

    Hi Charlie & Others - well, I'm back home and looking at the Samsung T5 SSD again - found this discussion from the CCC people which solved my conversion of the SSD to APFS - first step was to select 'View All Devices' > Select the Samsung Device > Now able to pick APFS & GUID partition. Final pic shows my SSD renamed and formatted as APFS - SUCCESS! Thanks to Bombich. Dave
