Look for the manual for your RAID system. It may be a file on a CD of utilities that came with your computer or mobo, if you are using the RAID capabilities of the mobo disk controllers. If you can't find it, see if you can determine exactly which mobo chip type you have for the disk controllers, and check the website of your computer maker (or mobo maker), or, if necessary, the website of the chip maker.
