mounting: audio vs data cd's

[Debian User <jensenb@charter.net>]

Greetings fellow Debian users!

I can mount/unmount my cdrom with data cd's using mount /cdrom.  The fstab is:

/dev/hda2       /               ext2    defaults,errors=remount-ro      01
/dev/hda1       none            swap    sw                              00
proc            /proc           proc    defaults                        00
/dev/fd0        /floppy         auto    defaults,user,noauto            00
/dev/hdc        /cdrom          iso9660 defaults,ro,user,noauto         00
/dev/hda3       /win            ext2    defaults,ro,user,noauto         01

When I put an audio cd in and mount it shows:

mount: wrong fs type, bad option, bad superblock on /dev/hdc,
       or too many mounted file systems

I have ata/ide/mfm/rll support and ide/ata-2, ide/atapi cdrom compiled in the 2.4.0-test7 kernel.

Anyone have any ideas why a data cd comes up fine but an audio cd balks?

Pondering,

Bill
