/dev/hdc    /media/cdrom0  udf,iso9660 user,noauto,ro   0   0
/dev/dvd    /dvd           udf,iso9660 user,noauto,ro   0   0
/dev/cdrom  /cdrom         udf,iso9660 user,noauto,ro   0   0

/dvd and /cdrom are symbolic links to /media/cdrom0. I would eliminate 
the /dev/hdc line completely and make /dvd and /cdrom proper 
directories, but that breaks synaptic.

Not as far as I can tell - that was the first thing I looked for.

No. The message disappears when there is a CD or DVD in the drive.

No. It starts during bootup, as soon as the ide interfaces are probed 
and hdc is found. Here is an excerpt from the logs.

The nuisance error message is

hdc: error code: 0x70  sense_key: 0x02  asc: 0x30  ascq: 0x00

I also have Debian Etch installed on the machine. The error messages 
start at a similar place but are slightly different, as follows.

ATAPI device hdc:
  Error: Not ready -- (Sense key=0x02)
  Incompatible medium installed -- (asc=0x30, ascq=0x00)
  The failed "Read Cd/Dvd Capacity" packet command was:
  "25 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 "

I also have Libranet3.0 installed on the machine. The error messages 
are identical to those of Debian Etch but start a bit later in the 
boot sequence, but still well before booting is complete.

The simplest thing to do would be to leave a music CD permanently in 
the drive but this offends my sense of what should be the correct 
operation of the machine.

Any suggestions would be much appreciated.
