what do you mean molex connection?
here's some test that i did. i initially thought some software issues might be triggering it so i indeed try to disconnect the IDE cable but still the problem was persistent, it keeps opening the tray and closes it afterwards and its doing that very often and it wakes me up when I am sleeping.
do you think its my power supply? if it is so, then shouldnt it affect my harddrive as well? my harddrives seems to be working just fine.
but just to add some background, i used to have Liteon 24x burner and i also had quite a few problems after using it for like 2 months, but it isnt as bad as the one on this benq dvd writer, my liteon wont let my cd tray open, as soon as i hit the eject button, it closes right away so I had to be quick, but thats the only problem, that liteon drive doesnt open by itself and it ejects when I hit the eject button.
