DiskWarrior for macOS will recover your documents, photos, music and any other files when disaster strikes and you lose access to your files.

Features and Highlights

DiskWarrior gets you back up and running fast!
Perhaps you've tried to open a document and all that happens is a color wheel that spins and spins and spins… Or your Mac no longer starts up… Or your external hard disk no longer appears… Or your MP3s won't play... Or every time you look through your photos, your Mac crashes. These might indicate directory damage or even a pending drive failure.

DiskWarrior repairs disks no other utility program can repair
With a single click, the program reads the damaged directory and finds all salvageable files and folders and builds a new error-free, optimized directory for you to use.

DiskWarrior repairs those cryptic errors reported by Disk Utility
Messages from your Mac such as "Invalid node structure" and "Keys out of order" may seem mysterious or even scary but the program fixes these problems and many, many more.

DiskWarrior saves your hard-earned money
You can try other utilities but you'll probably end up needing the app to recover your data. You'll save money buying the tool first.

You can easily check if your missing documents and items have been recovered
The program's patented 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
The tool 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 monitors your drive's health
Using SMART technology, DiskWarrior for Mac can automatically test and alert you to impending drive malfunctions.

DiskWarrior is so advanced it can even recover your data from a failing drive.
Just plug a new drive into your Mac and let the app copy your good files from the failing hard drive to the new drive.

DiskWarrior diagnoses common file problems
File paths, permissions, invalid plists and other problems are tested to ensure your files can be found when you need them.

What's New in DiskWarrior?

Ships on a bootable flash drive to repair your startup disk
Flash drives start up much faster than DVDs and can be updated as needed.

64-Bit
Today's large disks can have large directories. Using the latest 64-bit technology allows the app to handle even the largest disks.

Includes the new DiskWarrior Recovery Maker
New Macs have new OS X startup requirements. The app Recovery Maker updates your Recovery flash drive with the latest OS X.

Runs from OS X Recovery (Recovery HD)
In an emergency, you no longer need a separate startup disk to run the app on your startup disk unless your startup disk has partition table damage.

Repairs partition table damage
Sometimes the damage is to the map that describes all your drive's partitions which makes all your partitions unavailable. The tool can repair standard Mac GUID partition tables when started from the DiskWarrior Recovery flash drive.

New architecture
Updated to use the newest OS X technologies while still supporting older PowerPC and Intel Macs that can no longer run the latest OS X.

Significantly faster
For many disks, directory rebuilding is twice as fast as the previous version.

Recovers more data from drives with hardware malfunctions
Recover your important files from most failing drives, possibly saving you thousands of dollars in professional recovery costs.

Detects and repairs more disk problems than ever
The best is even better.

New Directory Optimization Index
You can tell how efficient your directories are at a glance.

Repairs Time Machine backup disks
Drives containing Time Machine back ups can have enormous directories that were often too large for the app. The 64-bit memory addressing of Disk Warrior allows these drives to be repaired or recovered.
