Unable to add 2nd HDD

Hello,

I had a Maxtor One Touch that when I tried to access it through My Computer, was asking me if i wanted to Format the Drive. I was hesitant to do this because I didn't want to lose all of the data stored on it. I ended up taking the HDD out and trying to directly add it to my PC as an Internal Drive, as after all its just a Seagate HDD in the box.

I have connected the drive internally, but I am not able to get the BIOS to recognize the drive. I have double checked that the power/data cables work, and that the port is active and working. When I boot up my computer it says that drive is not recognized.

The drive itself seems to be humming, so I am assuming that it is spinning.

I believe that the factor settings for my primary drive is to be in Raid 0.

The only thing I can think of is that either the raid settings, or the maybe the drive controller is not active for that port? Either way, I cant seem to figure out how to fix that. How do I get the Bios to recognize my 2nd drive? All I am looking to do is be able to access the files on that drive. After that, setting it up as internal storage is all I would want it for.

I am running XP SP3. Any help would be appreciated.
