Take a look at the screenshot below. You'll see that it's of my RAID 0 set-up and was benched tonight (Saturday). The problem is that they won't complete a full chkdsk and always gets stuck on 50%. Now obviously I'm thinking one of the drives is about to give up although the benches show that it's still giving great performance. So does anyone know what could be causing this? Is a drive about to fail or does the answer lie else where?
