sudden CD burner failure



I burned a CD using an iso image.
The CD worked.  It is mountable.
It's files are there.
Feeling paranoid, I tried to burn
another CD with the same image and
the same command.  cdrecord didn't
give me any complaints it hadn't
given me before, but the CD didn't work.
mount /dev/hdd
produced
/dev/hdd: Invalid argument
mount: /dev/hdd: can't read superblock

Some of my effort:
