Well I know spyware cannot corrupt systems; only bog their performance down. And Virus eat away system resources or even completely shut a system down. But a virus made to show that a CD burner is not working.... what would be the point of that?

Maybe the FBI sent it to you in retalliation to the piracy thing. I dunno...

All I know is... without a "Drive Missing Virus" the only way the internal drive could be missing is Drivers or firmware updates.

And being a computer science study, You don't actually have to delete the drivers yourself. There could've been a third party application that came in conflict with the drivers themselves and either overwrote them or just completely got rid of them.

Your best bet is to just re-install it with the CD it came with and with the drivers.
