I got an SATA HD for my 1.6 G5.... I installed it... took a couple times before the G5 recognized it. ( I had to change the jumper on the back). Now the disk is shown on the desktop... but i can't reformat it. It works, but I can't format it. The SATA ran in RAID 0... but I have no clue what that is. I open the HD on the desktop and it shows a bunch of Windows NT files, but I want them to be removed. Disk Utility isn't helping...can anyone help me??
