We are running on a eMAC G4 1Ghz OS v10.2.8.
From the Diskwarrior website under Mac OS X Compatibility it states the program PlusOptimizer , "will optimize Mac OS X Extended disks while running under Mac OS 9.x." You can check for yourself here:
However, underneath that paragraph, it states, "PlusOptimizer cannot optimize any disks shared with Mac OS X while running under Classic. PlusOptimizer will not optimize UFS disks."
Does "Classic" mean booting up in OS 9? If so, then how can I use PlusOptimizer to optimize my harddrive that contains both OS X and OS 9?
