Hey, you've probably come across the problem before, and yes i have found the solution but i cannot do it because both my dvd-rom and cd-rw drive will not open, help!
that hole is for emergency or non-powered ejection of the disk from the rom drive. all desktop rom drives have that hole & it won't hurt the drive.
...And most laptop drives as well. The drives used to come with something that looked like a bent paperclip just for this. Becides, if you can't get the disk out, then the drive is already broken!
