Sorry didn't get back sooner, been really busy last couple days.
I ordered the PC from Dell back in March of 2010. I may have requested Raid setup but never bought the second HD as I may not have wanted to pay Dell's price. I really don't remember what happened or how I ended up with a single HD setup as a RAID but that was the case. Only one HD in the box when new.
Ideally, I would like to be able to connect the bad drive to my current setup which is a single drive set to SATA and attempt to retrieve some of my old pics, music and docs. I know I failed miserably at maintaining a proper back up, especially since I have a nice 500G portable drive that was bought just for this purpose even before I bought this PC!
As I said in my OP, my BIOS won't allow both a RAID drive and a SATA drive active within the system. I can only boot to my SATA HD so what are my options as far as connecting/reading the old HD?
