You said that

I plugged it back in and re started the PC, the BIOS couldn't detect the floppy drive.

I'm guessing that the Bios is detecting everything else. Flip the cable and see if that works. If you did fry the drive, the cost of floppy drives these days are pretty cheap, you should not be out much money. You maybe able to talk a freind into giving you a floppy drive out of an old unit to test to see if that's all it is. If it still doesn't work, I would say the trouble is in the board. If that is the case, I would take it to a pro and have it tested. Peace.
