Second, no G4 was shipped with more than one drive installed unless it was a "BUILD TO ORDER" purchase. Third, use Disk Utility to erase and format the drives. That will restore the available capacity of the drive to the original "new" capacity. Of course, you WILL lose any data that is on the drive when you do this. Fourth, you should make sure that your drives do not have a bridge installed on the drive size limiter pins. That will limit the space available for use (according to the PC tech here in the office). I have never seen a size limiter bridge on a drive in a Mac chassis, so I can't verify the truth of his statement.
