CDROMs read/write no problem.
Just to confirm: it's a hardware problem and I should call Dell?
First, check to see if anything is mounted in /media/cdrom (or equivalent optical drive). Also, make sure you're trying multiple media types (retail dvd, burned dvd image and data dvd). It could be an issue with the fs type on the dvd.
If it's detecting in bios then boot w/f12, select 'boot to utility partition' or 'diagnostic partition' (if you haven't blown the partitions away completely the diag partition is there; if not then use the 'drivers and utilities' disk, which may also be labeled as 'resource disc': the diags are on there). Once you get in to the Dell 32bit diags go to 'Custom Test' then highlight your optical drive and run all tests (without a disc in there; if you had to use the resource cd method make sure you take that disc out of the drive before starting or it will throw an error). If you're not getting any errors then it's not the drive itself.
If you didn't get any messages then get back to linux and drop a disc in. Make it a retail dvd, whether or not you can play it, and force the mount type:
mount /dev/<your dvd drive> ./dvd -t iso9660
See if that will mount it and make it readable. Too late at night, can't think of anything else. Good luck, post your results.
