DiskWarrior 2.0 -- Alsoft has introduced DiskWarrior 2.0, the latest version of its data recovery and directory optimization tool. In addition to its lauded directory optimization, fully functional preview feature, and near-magical CD-ROM that can start up a wide range of Mac systems (see "Fighting Corruption with Alsoft's DiskWarrior" in TidBITS-486), DiskWarrior 2.0 adds DiskShield, a new feature that checks the validity of any directory information being written to or read from your disks. In theory, DiskShield could prevent directory damage from occurring in the first place and alert you to potential problems before they grow into catastrophes. DiskWarrior 2.0 also includes the capability to graph fragmentation in disk directories so you can get an idea how much an optimized directory might help. DiskWarrior still lacks traditional disk optimization and brute-force data recovery offered by other disk recovery products, but the DiskWarrior CD ships with Alsoft's PlusOptimizer, a disk defragmenter that can be used on Mac OS Extended Format (HFS Plus) volumes. DiskWarrior 2.0 is $70 plus shipping; currently the download-only version remains at 1.1. Upgrades from previous versions of DiskWarrior are $30 plus shipping. [GD]
