Popular and powerful disk utility.

Overview

DiskWarrior is the essential Mac disk utility.

Everything just disappeared after your Mac went haywire. All your work documents. The music you most enjoy. The movie of your kid's first steps. It's your life and it's gone. Don't panic! DiskWarrior will find your documents, photos, music and any other files when disaster strikes and things go missing.

Perhaps you've tried to open a document and all that happens is a color wheel that spins and spins and spins? Or when your Mac starts up, all you get is a blinking question mark? Or you were in the middle of editing a movie and now your external hard disk isn't on the desktop? Or your MP3s won't play... Or every time you look through your photos, your Mac crashes. DiskWarrior gets you back up and running fast!

  • DiskWarrior repairs disks no other utility program can repair: DiskWarrior can find your missing documents and files. Using a patent-pending, award-winning method of rebuilding directories.
  • Just one click finds everything that's missing or broken. With a single click, DiskWarrior finds all salvageable files and folders and builds a new error-free, optimized directory for you to use.
  • You can easily check if your missing documents and items have been recovered. DiskWarrior's preview feature lets you see how your disk will appear after it is repaired, but before any changes are made. You can even compare your disk in its damaged state to its repaired state.
  • DiskWarrior is incredibly safe to use. DiskWarrior verifies your repaired directory to ensure it is error free. It then uses a fail-safe method of replacing the damaged directory to ensure that interruptions such as power outages won't harm your data.

DiskWarrior has been the best, most essential disk utility for as long as I can remember. When everything else failed to help you - including Apple's own Disk Utility - and software was telling you that your only answer was to reinstall the OS...that's when DiskWarrior would simply fix everything. No problem. No biggie. There you go...all fixed. It was incredible, and indispensable. For the moment, until it can be updated to work with APFS, the application I loved so much is useless. Kaput. It has value only for the very small minority running earlier OSes. So - I just don't get it, guys...are you REALLY charging $120??? How can you justify that? I think you should be giving this version away - just to keep some users of old systems something to get them interested until you have the new version. And the big question: will we ever see a new version? Seriously guys - will there ever be a new version of DiskWarrior that can do with APFS what it did for HFS+?

Once the best disk utility repair app for Mac's.. Now a shadow of its former self, and has little use with the latest Catalina OS on Mac's. $120.00.. I don't think so.

Can anyone please confirm that the Alsoft website is dead? Does this mean that the company no longer exist and we have to say RIP to DiskWarrior?

From Alsoft.com: "The next major release of DiskWarrior will include the ability to rebuild APFS disks. Apple released a portion of the APFS format documentation in September of 2018 . Our developers are now waiting for the remaining portion of documentation to update DiskWarrior in order to safely rebuild Apple File System (APFS) disks."

So if I interpret to what you say , Apple has found a way to protect its users for others to corrupt the OS.? I guess this is the price us users had to pay

This shouldn't be a review. It's presumably supposed to be a reply to my comment?

In which case, no, users didn't have to pay this price, and neither did Alsoft, Coriolis or Micromat. I can't speak for the others, but I know Apple historically issued me a *special* developer certificate with some extra flags in it that let me do one or two things that normal developer certificate holders can't do. There's really no reason it couldn't have added facilities to SIP to allow non-Apple-signed binaries with a special flag in their signature to have similar access to Apple-signed software like Disk Utility. It just didn't do that.

There's also no good excuse for shipping APFS nearly a year before publishing any kind of documentation for it, and then presenting us with essentially a reformatted dump of a header file or two.

Nor is there any good excuse for keeping trustworthy utility vendors out of the App Store, particularly given that there are phoney disk utility products near the top of the paid chart half the time.

Your do right I stand corrected. But I spent good money for something that I can’t use now and again the customer is stuck in the middle.

People need to understand that the problems with disk utility software on newer macOS versions are caused by decisions made inside Apple, not least the decision to ship a new file system that is still, AFAIK, not properly documented. I used to run Coriolis Systems (now sadly gone), and it pains me to see that Alsoft is still stuck in the mess I was in before I decided to call it a day. Someone said Micromat has APFS support, but I think I’m right in saying that they just run Apple’s fsck tool in the APFS case (apologies to Micromat if I’ve misunderstood and they’re doing more than that). DiskWarrior clearly can’t do that - it’s entire reason for existing is that it was way better than anything that came with the machine. Anyway, while it’s reasonable to wish for a new version with APFS support and without all the problems cause by SIP, it’s really unfair to blame Alsoft for any of this. The blame lies with Apple, who don’t currently seem very keen on third party disk utilities, even from vendors who have proved themselves trustworthy over the years since Mac OS X first shipped.

Does anyone know when Alsoft are going to come out with a major update to DiskWarrior? Seems to me that it's now been so long that Mojave's been out with no new version of DW to work with it, that surely the company must be in trouble. Up until I upgraded to Mojave last year I'd always run DW about once a month and it never failed to keep my Mac in tiptop running order. I've now been without DW for so long that it's starting to look as if they're just never going to release DW 6. I'm regularly checking Alsoft's website, but it never changes, 5.2 being the latest version. They must be losing a great deal of revenue with Mac having been on Mojave for such a long time now, and a version of DW not to have been released that can rebuild it. I'm loathe to shell out for something like Techtool Pro, if I go and do so only to see a new DW come out the day after.

I would go with an alternative. If or when it does come out, it might not work as intended and their customer service will not help you and turn around and blame you.

felipey has no idea what he's talking about. DiskWarrior has been around a long time, and has saved a LOT of Mac users' rear ends. It is a fantastic product that is sorely missed right now. I appreciate Alastairh's replies and clarification here on the board. I do wish however, that we could have some regular feedback about timelines, progress, etc.
