    if i put slackware's packages cd etc  during boot time it mounts it with no problem

    if i were to put in a music cd it would say it cant mount ( dont know the format etc..

    things are worse if co cd is put  during boot ... it says  hdd: tray open .. atleast 25 times and finally  tells me about a bread failure etc..
  i am using bare.i images of slackware
    what is the above problem..
    can i avoid such a embarassing situation??

ISO9660 is the standard. From there you have "extensions". The one we use is rock ridge, which has device special files, unix modes, owner and group, etc. There are others...

A music cd DOES NOT have an iso9660 format... no filesystem, just digital secuential data accessed by "seconds from the start" with a small index at the beginning...

Other formats could be a photo cd, etc.

So, the only cd format you can mount are iso9660. And the only way to get rid of the annoying messages is to disable them from kernel, but you will lose other disk VERY IMPORTANT error as disk or controller failures.

In my linux box, I've added the noauto keyword to /etc/fstab

/dev/hdd   /mnt/cdrom   iso9660 user,noauto,ro       0 0

This causes that the cd won't auto mount at boot, and ANY user is able to mount it with:

% mount /mnt/cdrom

Your mount point may be different...

And yes: you surely have a double ide controller and you will have:

first controller     master       hda
first controller     slave        hdb
second controller    master       hdc
second controller    slave        hdd

Good luck,
