Having trouble re-installing Vista

I first installed Vista last year with 2 500GB SATA hard drives in Raid 0. Set the IDE controller to RAID mode in the BIOS. Configured the RAID hard drives as a Raid 0 in the config. Installed the RAID drivers from the mobo during the Vista install procedure and the volume appeared in the list ready to install Vista onto, everything went as it was supposed to.

On sunday however, one of the hard drives died on me and now I am attempting to re-install Vista on the hard drive that is still working. I removed the hard drives from the raid array in the config, set the IDE controller back to IDE mode, made sure the hard drive was in IDE channel 0 as the master and that it was detected fine by the BIOS. However, when I run the vista installer, the list of places to install it to was empty.

Thinking it might still have some remnants of the RAID on it that might be causing a problem, I put the hard drive in my friend's Vista machine and did a full format on it, and tested that it could be read from/written too fine and it could. The hard drive works fine in another computer, so I'm pretty sure there is no fault with it. It can even be seen within the Vista installer if I go to the repair tools section and brows the drives there, for some reason I just can't get it to show up on the list of possible destinations for the vista installation.

Can anyone suggest a possible cause and/or solution to my problem.

Mobo is a DFI Lanparty X48 btw.
