DVD-RW drive not reading discs


this is a noob question I'm sure but it's also hardware, so...

Installed Ubuntu 10.10 this morning from CD, downloaded all the latest updates. But when I put a CD or DVD in the drive, I can't access any of the data. Disk utility recognises that the drive is there, but it says "No medium detected".

Disk utility recognises it at /dev/sr0 so I added a line to fstab

/dev/sr0 /mnt/dvd udf,iso9660 user,noauto,exec 0 0

but made no difference. Any help/ideas would be much appreciated. Cheers

I had a similar problem when running Ubuntu 10.04 in the 64-bit version, one reason to turn to the 32-bit version.
Are you running the 32-bit version or the 64-bit?

This has been discussed many times at length, e.g.

Sometimes runnung hdparm -tT /dev/sr0 a few times with a prerecorded cd fools it into working for a while
