Hm...Martin, this is a laptop. No cabling problems. I think I may have
had a CD in there instead of a DVD; both were brand new, "blank" media.
I can put in a DVD I've burned or a commercial movie, any CD I've put
anything on or a mass-produced music CD - and all is fine. It's the new,
"blank" media that won't work.

This drive not only worked fine under Windows, it worked fine under
Gutsy! At least as far as reading blank CD-ROMS and burning whatever I
wanted to them. I had not tried to burn or read DVDs yet.

Here's a thing: I ran dmesg | tail with a CD I'd put artwork on in the
drive. Still got the same I/O errors, just lost the UDF-fs errors. Yet
the CD is reading beautifully.

After the CD, I put the blank CD and the same DVD from before in and
got:

[EMAIL PROTECTED]:~$ dmesg | tail
[212982.279995] end_request: I/O error, dev sr0, sector 324

[212983.239757] end_request: I/O error, dev sr0, sector 344

Note the lack of UDF-fs again? But those errors were there the first
time I ran the command on this same blank media!

Anything else I should try?
