has released version 3.0 of DiskWarrior, a new version of the disk utility that adds native Mac OS X directory rebuilding for Mac OS X Extended disks, as well as disks running under earlier versions of the Mac operating system.
DiskWarrior fine-tunes your hard drive by ordering the directory structure efficiently and by defragmenting the disk contents. In addition to native Mac OS X directory support, version 3.0 offers increased performance, support for journaling, and a component that uses a drive’s built-in S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) technology to monitor drive hardware, according to Alsoft. The latter feature give you a chance to back up your data if the hardware is in danger of failing.
DiskWarrior 3.0 keeps the application’s ability to compare the existing directory with the rebuilt one, a feature that shows you which files and folders have been affected by directory damage before any changes have been made to your disks. The utility can also generate a graph showing the state of fragmentation of a disk’s directory.
The retail price for DiskWarrior 3.0 is US$79.95; upgrades from earlier versions are $39.95. Site licensing and volume purchase discounts are available.
DiskWarrior supports any Mac OS Standard (HFS) or Mac OS Extended (HFS Plus) disk. You’ll need a G3 or better Mac with at least 128MB of RAM to start up and run from the DiskWarrior CD. If you’re running a Power Mac that’s incapable of running Mac OS X, the DiskWarrior CD will start up an earlier version of the Mac operating system and let you run DiskWarrior 2.1, which is also included on the DiskWarrior CD. However, to install the DiskWarrior application, you need to be running Mac OS X 10.2.1 or later. DiskWarrior supports SCSI, IDE, FireWire, and USB devices and is compatible with any storage medium formatted as a Mac disk.
