Alsoft's DiskWarrior Combats Directory Damage -- The folks at Alsoft, makers of DiskExpress Pro and PlusOptimizer, have released DiskWarrior, a new disk repair utility with a unique approach to recovering data. DiskWarrior focuses exclusively on directory data, pulling out as much information as possible and then creating a new, optimized directory, which the user can preview before saving changes. DiskWarrior won't be able to repair corrupted or damaged files (and doesn't seem to offer other traditional file-based features, like an "undelete" option), nor would it be able to help if a disk's directory is very badly damaged. Nonetheless, it might be useful for recovering missing folders or files or nipping subtle directory problems before they blossom into catastrophes. DiskWarrior costs $70, and supports HFS and HFS Plus volumes on IDE, SCSI, and USB devices. DiskWarrior requires a 68020 processor or better (including PowerPC), at least 16 MB of RAM, and System 7.1 or higher. [GD]
Syslogd Overwhelming Your Computer?
If your Leopard (Mac OS X 10.5) system is unexpectedly sluggish, logging might be the culprit. Run Activity Monitor (Applications/Utilities/ folder), and click the CPU column twice to get it to show most to least activity. If syslogd is at the top of the list, there's a fix. Syslogd tracks informational messages produced by software and writes them to the asl.db, a file in your Unix /var/log/ directory. It's a known problem that syslogd can run amok. There's a fix: deleting the asl.db file.
Launch Terminal (from the same Utilities folder), and enter these commands exactly as written, entering your administrative password when prompted:
sudo launchctl stop com.apple.syslogd
sudo rm /var/log/asl.db
sudo launchctl start com.apple.syslogd
Your system should settle down to normal. For more information, follow the link.
