What's new in DiskWarrior?
DiskWarrior 5 is now the one utility program that solves all of the common problems you'll likely encounter on your Mac. Just look at these new features:

64-Bit
Today's large disks can have large directories. Using the latest 64-bit technology allows DiskWarrior 5 to handle even the largest disks.

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.

Includes the new DiskWarrior Recovery Maker
New Macs have new OS X startup requirements. DiskWarrior Recovery Maker updates your DiskWarrior 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 DiskWarrior 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. DiskWarrior 5 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 DiskWarrior 4. The 64-bit memory addressing of DiskWarrior 5 allows these drives to be repaired or recovered.

Plus a lot more
Purchase a new copy or upgrade now from older versions of DiskWarrior.

Please note that to install DiskWarrior 5, your Mac must start up in OS X 10.5.8 or later. This is a change from DiskWarrior 4 which supported installation on older versions of OS X. Please read the system requirements for DiskWarrior 5.
