somebody please help me. my compaqs hp 300n dvd drive doesn't read or write dvds. i have no idea as to what the problem might be. i have downloaded the firmware update from hp. but nothing. it couldn't play dvds for a while now. i did a system restore back to factory default awhile ago and it breifly played. but i have too many files on the computer now to do it again. since i cant play or burn dvd's i cant back up the system. i do know that my brother switched the dvd drive with the cd rom drive but then switched it back. this could be the problem but i do not know. please help me to solve this problem. this is the family computer so i can't do too much.
