Ok we are having a problem with our Hard Drives that are part of a RAID. We are connected to a G4 Tower, running OS 10.4.11. We have 4 120GB Hard Drives in set up in a RAID. Now all of the sudden the mac won't mount the RAID. I open Disk Utility and it only sees 2 of the 120GB hard drives, and says they are offline (I'm guessing because it needs the other 2 drives in the RAID). The way it's hooked up inside is that 2 hard drives are connected to one part of the mother board, and the other 2 to another part of the mother board. Through problem solving I figured out which 2 were being seen and which 2 were not being seen. So I took the 2 that were not being seen and used the power connecters and connecting ribbon from the drive that was being seen and plugged it into the mother board slot that was being seen. Doing this the Mac still did not detect the 2 bad drives. We plugged the 2 good drives into the mother board slot that wasn't seeing the 2 other drives, and it did see the 2 good drives. To me this says, it isn't the mother board slot, it isn't the ribbon, and it isn't the power connector. However, if the drives were bad wouldn't the Mac be able to at least see them, and just give an error that they cannot read them? Anyone have any suggestions?
