Comment 3 for bug 220957

Not quite same here had no problem in Gutsy but with Hardy on 2 similar pc's both running 8.04 and patched up to date. When I insert a blank dvd or cd nothing happens. If I try and burn using Brasero for e.g. it reports "no disc" in drive.
fstab gives following for cd/dvd:
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0

other commands tried and their results:

1) with blank dvd in drive: sudo mount /dev/scd0 /media/cdrom0
mount: No medium found

2) with blank dvd in drive: sudo lshw -C disk
