I have been having this problem since I got a new system a few months ago. My NEC ND-3500AG drive seems to lock after I have used it. For example I would burn a few dvd’s etc then when I close the drive empty the light sticks on and when I try to eject nothing happens for about 1 minute then it finally ejects.
This never happens with a dvd/cd in the drive and if I leave it alone the light just stays on until I shut down. It doesn’t affect anything else in windows or my other drive or running any programs. Sometimes when I have been using the drive and I reboot windows, the dvd light sticks on and windows loading hangs on a black screen until I press the eject button on my drive. Again this only happens when the drive is empty.
Apart from this problem, the drive works perfectly. It has burned all dvd’s I have tried with no problem at all and plays everything ok too.
Any help on this would be much appreciated.
