That comes back with 'No such file or directory'.  However:
 
   ls -l /dev/cdrom*
 
on this machine comes back with:
 
  lrwxrwxrwx   1  root  root     8 Jan  4 12:33  /dev/cdrom -> /dev/hdc
 
Which at least tells me the device that is available here, but there is no
difference when I put a disc in the hole.   I also tried the technique on a
machine with two DVD drives, but this was quite confusing because it indicated
that the cdrom was hdd, but the TC Mount Tool thought that the CD was in hdc!
 
The TC Mount Tool may well give sufficient clues though because it seems to be
able to work out what drives the machine has and also the volume names of each
disc in each drive.  Maybe the source code for this will let us into the secret.
