Ok, so I've got... well a pretty generic lite-on CD-ROM drive that was working quite well until this morning. Now my mobo can't detect it. Checked the jumper (it's IDE and set to master for its channel) and even switched channels. The HDD, unformatted for that matter, is recognized no matter where I put it, but the CD-ROM is just not working anymore.
For $30 to $35 can get a good DVD burner, e.g., Samsung or Lite_on, wouldn't waste my time on it. It's still under warranty, send ti back. I'd still get a DVD burner and if they send you a new one, you have a back up
