Bad Power Mac G4 Hard Drives -- Apple has revealed that some Power Mac G4s (Digital Audio - those released in January of 2001) contain defective 40 GB and 60 GB hard drives that can damage files, cause data loss, and potentially prevent the computer from starting up. Only a limited number of machines sold in the U.S. and Canada are affected, so if you have a Power Mac G4 (Digital Audio) with a 40 GB or 60 GB hard drive, read the Tech Info Library's instructions on how to determine whether your Mac has a bad drive. If so, Apple will replace the drive under warranty. [ACE]
Single Time Machine Backups
Tired of Time Machine running all the time? You can turn it off in the Time Machine preference pane, but still initiate a single backup by choosing Back Up Now from Time Machine's menu bar icon. Of course, your backup is much less likely to be up to date, but Time Machine won't be taking any resources while you're trying to work.
