I have a Clevo-based laptop akin to the Sager 9262 and one of my 3 hard drives just failed. I have 3 hard drives in RAID 0 and the drives are numbered 0, 1, and 2. The boot-up says the error is with hard drive 2, the last one on the list.

My question is, which of the three hard drives is hard drive 2? I need to know so I know which drive to return. No I can't ask tech support because they are on vaction this week

There is one hard drive under the battery, and two more stacked on top of each other in a bracket to the right (looking at the back, battery to the left). Which one is phisically hard drive 2?

Thanks in advance.
