Hi Kevin. If the drive doesn't spin down by itself (which you may be able to cause to happen by checking "put hard disks to sleep when possible" in the Enery Saver preference pane under OS X), just drag it to the trash to unmount it which will cause it to unmount and sleep. To remount it use the Disk Utility app. John On Nov 17, 2004, at 9:25 PM, Kevin Willis wrote: > I just started using the "sleep" mode on my G4 instead of shutting > down every night.
