what os are u using?

i had this similiar problem before. what i did was
start/control panel/system/hardware/device manager/dvd/cd-rom drives

i right clicked on cd drives and removed the drives under properties. then i rebooted and windows picked them up.

if you are using xp it is possible to do a system restore to a point where your drives worked properly.

hope this helps.
