my dvd-writer drive recently stopped reading disks. ive tried all sorts of different cd's and dvd's it dosnt read anything. its showing up in the device manager with no faults, ive removed the device and reinstalled windows drivers to no avail, i also have another dvd drive in the machine that works so i tried switching the ide cables around and the power connectors (although the power connectors seem fine as the drive opens/closes and the green light flashes trying to read stuff. when i put cds/dvds in it says please insert disk into drive... i also downloaded and tried a firmware update which said it installed fine but didnt solve my problem. the only thing i can think of that may have possibly destroyed the drive is using a cleaning cd in it. it was a wee while back but i cant actually remember if it was working after that. ive exhausted my ideas to fix it, think its just knackered? help appreciated
