Hi! I have a really stupid problem that I can't seem to fix. We have several Mac Pros here (early 2008). One of these had a Apple Raid Card (A1247 EMC 2156) and four HDDs in a raid. One day the mac pro just stopped working and after restarting it it had lost all harddrives. Now after many tries to get it to recognize the harddrives again I bought another raid card (same model) via eBay thinking the one we had micht be broken. I tried both cards in the broken down Mac Pro, the cards would be recognized but none of the disks or any other hdds I put in there are shown in either the raid manager or the disk utility software. If I start the mac without a raid card and with the iPass cable back on the motherboard the hdds are recognized. So I thought maybe the Mac Pro is the problem and installed the card in another Mac Pro, but there the same problem happens, again with either raid card. So regardless of what I use, with either raid card installed the mac won't show any hdds (even brand new ones) connected. I am not very well versed in the macs raid functionality, am I missing something? Shouldn't I just have to connect the raid card, plugin the hdds and then be able to use them? It's as if I had't connected the iPass cable, but I did... If anyone has any ideas of what I could do I'd be really grateful!
