I have a Power Mac G5 Dual 2.0ghz computer. I bought it as is and it wasn't working. I replaced the motherboard. It came without a Hard Drive. Now with it booting, I put in one of my used SATA hard drives and neither them would show up when I tried to install OSX. One was formatted in a linux file system, the other NTFS. One is a Maxtor, the other a Hitachi. My question to you is will these work with my G5? Or is there a compatibility issue? Is it because of their current file system or the brand of the hard drives or perhaps another issue. Thanks.
