My dell inspiron N5050 's dvd drive is not working properly.after inserting the dvd in the drive,formating process is starting and the disk is showing zero memory although i know it can't erase any information from a cd.
Does it boot from a bootable CD/DVD? If that works, then a driver may be the issue; otherwise the drive is defective and there isn't much that you can do other than replace it (or clean it if it's dirty, but I've rarely seen that issue).
