Cannot uninstall programs due to harddrive failure

[Rocco360]

I'm new to this thread thing so bare with me. I own 2 500 gig Seagate hard drives and recently the secondary hard drive has died. Well I think its died since windows doesn't even recognize it. Anyway On that hard drive i kept my video games a photos and such so I lost all of them and I'm replacing it but whenever i try to install my games to the original hard drive for example a program for games called Steam it says "Error 1327.Invalid Drive:L\". So yeah ofcourse it says that because it cant regognize the hard drive but there seems to be no way to get the remenints of all the games off the main drive. I have tried to delete the games through the registry by following the microsoft instructions but the games still show up in the Add/Remove Programs application. Now i seem to be stuck so any help would be greatly appreciated.
