Re: RAID 1 or 2??
At boot-up, there is usually a set key(s) that you need to press to get into the RAID utility. Usually, it's Ctrl+H. You can also look in device manger, and see if the other hard drive shows up- it is possible that it's not setup in a RAID, but more than likely it is, in a RAID 1- which is mirrored.
