Thanks for those examples, Stuart.
Unfortunately, dd doesn't want to work with this crappy CD:
# dd if=/dev/acd0t01 of=track1.cdr bs=2352
dd: /dev/acd0t01: Device not configured
0+0 records in
0+0 records out
0 bytes transferred in 0.000179 secs (0 bytes/sec)
Yet:
$ ls -l /dev/acd0t01
crw-r----- 1 root operator 0, 91 Nov 30 23:27 /dev/acd0t01
