Hello, Yesterday I got a MacPro early 2008 (2x3.0) that has an Apple Raid Card installed. With it came three HDD's setup as mirrored RAID. Not knowing enough about the RAID, and not having the need for it, I just removed the 3 drives and installed my own 4 drives that had lived in another MacPro. The drive with the OS-X and another drive showed up on the screen, but the other two did not. I put them in different bays and ejected the second working one, but these two never showed up on the screen. Then I put them in an external dock, and they showed up right away. So something in regard to the RAID card is causing this. Is it the card itself that prevents 4 internal drives from working at the same time? I'd much rather change the setup than remove the card if that's possible. If not, then how easy is it to remove the card? Another question, does anyone know if Apple will diagnose a problem on an out-of-warranty desktop for free? Thanks a lot!
