View Full Version : [kubuntu] Optical drive non-responsive after killing kio

A couple days ago running Kubuntu 10.04 on a Dell Optiplex 780, while in the midst of changing CDs that I was ripping music from, I was alerted that the optical drive (DVD - R/W) was in use by another application. I searched around, found nothing using the drive and opted to halt the offending application, which if I remember correctly was audio-kio or something. I realize now that was probably a stupid move. The drive now doesn't respond in any way. The activity light flashes continuously. Curiously, it remains in this state whether I'm running Kubuntu or Windows.

examining the contents of /dev ....

It seems to me that my cdrom drive is no longer available as a device. The optical drive was never mounted by fstab, only hard disks and some SAMBA shares are in there.

Have I nuked my optical drive or what?? I've read on some other forums that checking the cables inside is a good idea, but I can't imagine they've come loose, as I've never had the case open. I'd greatly appreciate any direction you might be able to point me in to get this resolved...

Thanks for reading.

Does your BIOS still detect the cd drive? If not, your drive probably went bad.

Thanks for the reply. My BIOS did, recognize the drive though wasn't happy with it. What I did was shut down the machine with plug pulled for about 15 minutes. After starting up again, all was normal.
