Hey everyone, I've got a quick question and figured the scene would be the best place to have it answered. After all most of the members here know more about anything and everything than any other forum...so, hats off to you

Anyways, I've got an old server with a database on an old 20GB WD Hard Drive. It runs a POS system and its data is incredibly important. So, knowing that WD's love to burn out and it could happen at any time, I want to add another HD and set up a RAID 1 array. I've got two identical disks and a RAID card, but have never build an array from this point. I have always defined the array formatted and then built it up form there.

So my question is, where should I go from here? What is the best and easiest way to go from one disk to two in RAID 1?

Thanks!!
