I am buying a used Powermac, G5 Dual 2GHz. It already has a SATA 320GB HD in it but I want to use my SATA 160GB from my dead iMac. The only questions I have are: 1. Is there anything special I need to do installing the second SATA drive? Does the drive need to be set to Slave or Cable Select? 2. Because the 160GB (going to use for storing musc) drive has OS X Tger installed, will it be a problem when booting once I install both drives? The 320GB drive has Leopard (This will be my primary drive). Will it boot to Leopard and let me use disk utility for format the 160GB drive? Any info greatly appreciated!
