I have a hp Proliant DL360 G6
It has 4 hard drive slots and I have 2 Intel 80GB SSDs and 1 WD 160GB regular hard drive. I have tried the WD in all 4 slots and each time it detects it and boots right up into vmware so the slots arn't defective. But when I insert the 2 Intel SSDs the server doesn't see them on POST
