I have a HP Server with 4 x 1Tb SATA Drives with an Adaptec 2420SA Controller. There are a couple of issues. The server was powered down and only turned on now. It seems the Adaptec Controller has lost the two Arrays (ARRAY_0 was 10 GB and ARRAY_1 was 2.7Tb). To make matters worse, drive 4 is also clicking and fails to initialise. On the last power up, the Adaptec Controller no longer initialises. The client is wanting 2 folders on the second array i.e. photos and video. Can you assist?"
