DiskWarrior 4.4 for Mac

What is DiskWarrior?
DiskWarrior is the safest, most technologically advanced, most powerful utility to eliminate directory damage available for any computer.
DiskWarrior uses a different approach to disk directory repair than other programs.
DiskWarrior is not a disk repair program in the conventional sense. Instead of patching the original directory, it uses a patent-pending technology to quickly build a new replacement directory using data recovered from the original directory, thereby recovering files, folders and documents that you thought were lost and that no other program could recover.
How does DiskWarrior recover data no one else can?
At Alsoft, we know that the most important thing when you are attempting to repair your disks is getting your data back. That's why the first thing DiskWarrior does is scavenge your original directory to find all the file data it can. It then uses this data to build an entirely new replacement directory.
DiskWarrior is the only product that finds all of your data.
Its patent-pending method always results in a perfectly rebuilt directory without any errors and that contains all of your file and folder data.
Why Choose DiskWarrior?
DiskWarrior is a utility program designed from the ground up with a totally different approach to preventing and resolving directory damage which is the leading cause of Mac instability.

DiskWarrior resolves existing disk damage by rebuilding your disk directory using data recovered from the original directory, thereby recovering files and folders that you thought were lost. The directories DiskWarrior creates are also optimized for maximum directory performance.

DiskWarrior is not a disk repair program in the conventional sense. It does not attempt to solve all of the possible problems that can occur with a disk. It specializes in eliminating directory errors - the most common problems Mac OS users have with their disks.

DiskWarrior rebuilds your disk directories making them error-free, eliminating any problems the errors would have caused, and recovering lost files.

It fixes any problem with master directory blocks and alternate master directory blocks (HFS), volume headers and alternate volume headers (HFS Plus), volume bitmaps, catalog trees, and extents trees.

This approach has a significant advantage that the others overlook. Other products attempt to repair your directory one step at a time, ignoring the big picture of what is truly wrong with your directory, and risking file information that could be saved. Too often, they will incorrectly begin to "repair" your directory, and then give up when they realize that they have modified the directory to an irreparable state. At Alsoft, we know that the most important thing when you are attempting to repair your disks is getting your data back. That's why the first thing DiskWarrior checks is your directory data, and that's what it uses to create a replacement directory. DiskWarrior continues its rebuild operations unless no directory data can be found.

Directory damage isn't the only threat to your data. A physical hardware malfunction can cause intermittent loss of access to any data on the drive. If the malfunction is serious enough, the only way to retrieve the data on the drive is through an expensive data recovery service. DiskWarrior can be configured to automatically check drives for possible drive malfunction, giving you the chance to back up your data before a drive completely fails. The hardware monitoring can also be run manually if you suspect a drive malfunction.

Alsoft has been making disk utilities for the Mac over 20 years. Our disk optimization utilities have always chosen the safety and security of your data over anything else, and have been able to detect and report directory errors no other program can (the others obviously couldn't fix the problems they couldn't even find). That knowledge has been put into DiskWarrior to give you the only tool that can eliminate all directory problems and recover lost files and folders! And, as an added bonus, the directory DiskWarrior creates is optimized for maximum speed when accessing your files!

Requirements

DiskWarrior 4 supports any locally connected Mac OS Standard (HFS) or Mac OS Extended (HFS Plus) disk including RAID volumes, journaled disks, case-sensitive disks, FileVaults, Time Machine backups and iPods.
Startup Requirements
DiskWarrior now ships on DVD instead of CD. Starting up from the DiskWarrior DVD requires a G4 867 MHz Mac or better (such as a G5 or Intel Mac) with DVD drive and a minimum 512MB RAM. The computer must also have the latest firmware updates installed. Click here to learn how to repair the directory of a disk in a Mac model that cannot be started from the DiskWarrior DVD.
Installation Requirements
To install, you must be started from Mac OS X 10.3.9 through 10.7 with at least 512 MB RAM. DiskWarrior 4 version 4.4 is completely compatible with Mac OS X 10.7 Lion. Alsoft recommends that you don't run DiskWarrior 4 version 4.0 while started from Mac OS X 10.5 Leopard, 10.6 Snow Leopard or 10.7 Lion. Alsoft also recommends that you don't run DiskWarrior 4 version 4.1 while started from 10.6 Snow Leopard or 10.7 Lion. Instead, you should download the free DiskWarrior 4 version 4.4 Disc Update. This free updater allows you to create a new startup disc containing DiskWarrior 4 version 4.4.
Additional Requirements
If you plan to rebuild the directory on your startup disk, you need to start up from another disk capable of starting up in Mac OS X 10.3.9 through 10.7, such as the DiskWarrior DVD. DiskWarrior cannot be run while started up from the Apple Mac OS X install DVD.

If you plan to rebuild a disk that is encrypted with FileVault 2, you'll need to run DiskWarrior while started from Mac OS X 10.7. Alternatively, you can decrypt the disk then run DiskWarrior.

If you want or need to run DiskWarrior 4 version 4.4 from Mac OS X 10.4 or earlier, there are two features of DiskWarrior that are not available for a Mac OS X 10.5 through 10.7 startup disk. First, you cannot repair the permissions of a Mac OS X 10.5 through 10.7 startup disk. Second, you cannot rebuild a FileVault that was created under Mac OS X 10.5 through 10.7. You will be able to rebuild a FileVault that was created on a Mac OS X 10.4 startup disk that was later upgraded to Mac OS X 10.5 through 10.7. Your DiskWarrior DVD may start up in Mac OS X 10.4 and would therefore have these features disabled for a Mac OS X 10.5 through 10.7 startup disk. See the DiskWarrior manual for additional procedures to rebuild the startup disk.

If you want or need to run DiskWarrior from Mac OS X 10.6 through 10.7, there is a feature of DiskWarrior that is not available for a Mac OS X 10.5 or earlier startup disk. Specifically, you cannot repair the permissions of a Mac OS X 10.5 or earlier startup disk. Your DiskWarrior disc may start up in Mac OS X 10.6 and would therefore have this feature disabled for a Mac OS X 10.5 or earlier startup disk. See the DiskWarrior manual for additional procedures to rebuild the startup disk.

While started from the DiskWarrior DVD, you cannot repair the permissions of a Mac OS X 10.5 through 10.7 startup disk.

If you wish to enable DiskWarrior's automatic hardware monitoring, you will need to install the DiskWarrior application on your Mac OS computer. To install the DiskWarrior application see the install requirements above. Installing DiskWarrior is not required to run the application from the DiskWarrior DVD to rebuild a disk directory.
