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]
Improve Apple Services with AirPort Base Stations
You can make iChat file transfers, iDisk, and Back to My Mac work better by turning on a setting with Apple AirPort base stations released starting in 2003. Launch AirPort Utility, select your base station, click Manual Setup, choose the Internet view, and click the NAT tab. Check the Enable NAT Port Mapping Protocol (NAT-PMP) box, and click Update. NAT-PMP lets your Mac OS X computer give Apple information to connect back into a network that's otherwise unreachable from the rest of the Internet. This speeds updates and makes connections work better for services run by Apple.
