See what disk management reports. Go to Start -> Control Panel -> Administrative Tools -> Computer Management -> Disk Management to see what is listed there for hard drives, and which letters they are under.

Then you may wish to shut down and do a cold boot to give you a chance to select the key to go look at your BIOS to see what is detected there.
