Note: The “Startup Disk” of macOS Big Sur (11.0), macOS Catalina (10.15), macOS Mojave (10.14), and macOS 10.13 High Sierra with SSDs (Solid State Drives) cannot be rebuilt with DiskWarrior as they are automatically pre-loaded with Apple File System (APFS).
If that doesn't suit you, our users have ranked more than 100 alternatives to DiskWarrior and loads of them are available for Windows so hopefully you can find a suitable replacement. Other interesting Windows alternatives to DiskWarrior are Recuva (Freemium), Glary Utilities (Freemium), PhotoRec (Free, Open Source) and R-Studio (Paid). DiskWarrior is so advanced it can even recover your data from a failing drive. Just plug a new drive into your Mac and let DiskWarrior copy your good files from the failing hard drive to the new drive. Some bad blocks, bad sectors and media errors will not stop DiskWarrior. DiskWarrior diagnoses common file problems.
DiskWarrior 5.2 is NOT fully compatible with macOS 11.0 Big Sur. DiskWarrior Recovery Maker 1.4 is not compatible at all. Updates for full compatibility are coming soon. Please visit the DiskWarrior Compatibility with macOS 11 Big Sur page for more information.

DiskWarrior now ships on a flash drive instead of DVD. If you plan to rebuild the directory of your startup disk, you need to start up from another disk capable of starting up in Mac OS X 10.5.8 Leopard through macOS 10.15 Catalina, such as the DiskWarrior Recovery flash drive or your Mac's OS X Recovery (the Recovery HD). OS X Recovery is available in OS X 10.7 Lion and later.
Whether started from the DiskWarrior Recovery flash drive, OS X Recovery or another disk, DiskWarrior can run from the flash drive to eliminate all damage to any HFS (Mac OS Standard) and HFS Plus (Mac OS Extended) disk directories, including your normal startup disk.
Click here for step-by-step instructions on starting up from the DiskWarrior Recovery flash drive or OS X Recovery.
The DiskWarrior Recovery flash drive ships with the ability to start up any 64-Bit Intel Mac that currently starts up in Mac OS X 10.4 Tiger, 10.5 Leopard or 10.6 Snow Leopard. If you have a newer Intel Mac, you can use the included DiskWarrior Recovery Maker to update the DiskWarrior Recovery flash drive to start up your newer Mac.
