I have a powermac G5 dual 2.3 from 2005. I just bought a Western Digital 1 TB drive and tried to get it running in the second drive slot of my powermac. I've narrowed it down to this: -The drive just isn't compatible with mac -It needs to be pre formatted on a different computer It's not my sata connector or power connector because I connected another hard drive to the mac in that slot and it works fine. Also, I plugged the drive itself into a pc and it asked me if I wanted to format it for FAT32 or NTFS. So it's not the drive. I plugged it back into the mac and looked in disk utility and nothing showed up. I decided maybe it would show up if I formatted it for FAT32. It didn't. What should I do?
