Thanks for the help on this one guys, I really know nothing about setting up Raid. It will probably be best just to buy a new HDD and do a clean install. I don't have installation discs for that machine just the backup CDs it created and I know that those won't work on anything other than an HP machine .... I've tried using them.
So I will just get a new HDD and do it the easy way.
When I return from TX next spring I plan on putting both 5970s into that machine but 750W isn't enough to do it now and I'm running out of time. When that is finally done then I will have the 2 old servers that I can drop 6970s into
