My laptop's DVD drive has suddenly stopped working. All I know is that its not getting power. Now, I don't know whether the drive has gone bad or is there some other reason.
Drive was running all right till 2 days ago. But, all of a sudden, I loaded a disc, after which Ubuntu stopped showing drive at all. Its not even getting power. I don't what has happened. Now, I am using emergency exit and a safety pin to eject drive.
However, on checking through
lshw, it shows drive. Also, 'disk' shows it under devices. It even displays its serial number. Moreover, when I checked through K3B; it shows DVD drive as well, but 'no medium present'.
If I keep drive ejected and then run K3B, it shows no optical device found and
lshw shows status of drive as open.
Now I am confused where and what exactly is the issue. I beleive drive is OK and Ubuntu is even recognising it however the drive has gone switched off or suspended (if those things are possible).
So, please help me, how can I know whats the issue and diagnose it.
