I have a custom built server that is running a RAID 5 and RAID 1 split backplane. The OS is Win2003 and it is running an Adaptec SCSI RAID card. One of the drives recently failed and I went to install the new drive and rebuild the array using the adaptec manager (not in the OS) and it will not recognize the new drive. when i put the old drive back in it recognizes it but shows that it cannot rebuild it. i have tried 3 different drives and none of them show up so I figure that I am doing something wrong. Anybody know what I might need to do to get the new drive to show up? All drives are in bays and are hot swapable so all their jumpers are the same and I can't find any difference from the new drive and the old busted drive in terms of jumper settings etc. What am I not seeing/doing?
