From: Richard M. Kriss Subject: [G4] Re: Add 2nd HD to G4 Quicksilver Ray, [is a 200 GB that only formats to 128 on my G4. I don't need the extra space but it is there if I need it in the future.] Like the others have said just run the Disk Utility and format the drive. I use Carbon Copy Cloaner as a backup program and clone my Primary HD (the Seagate) to my BackUp HD (a Western Digital). Works great Richard... I've got a G4 733 QS I'm going to need to upgrade my hard drive pretty soon also. The old school way of formating a hard disk used to be partioning the drive into recognizable chunks like drive 1 would be 128 GB & drive 2 would be 72 GB. Does that not work anymore ?
