This is my fstab file

dev/hda4 / ext3 defaults 1 1
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0

And this is the message i get when i tri to mount a CDrom


mount /dev/cdrom
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
or too many mounted file systems
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)

What does it mean?

P.S. I also have a DVD player. Why is not it in the fstab list?

a dvd drive is treated the same as a cd drive.
perhaps your cdrom device is no longer linked to /dev/cdrom.

you can try
mount /dev/hdc /mnt/cdrom
mount /dev/hdd /mnt/cdrom
mount /dev/hdb /mnt/cdrom
mount /dev/scd0 /mnt/cdrom

and whichever works is your cdrom drive
then whichever works,
ln -s /dev/cdrom /dev/hdc
you may have to rm /dev/cdrom first

post the out put here of these two commands
dmesg | grep CD (if it doesn't work try lowercase cd)
fdisk -l
show's what you REALLY have... /etc/fstab is not what you really have, more what you are going to use...

Since you are trying to mount the drive "manually" I guess your request refers to slackware but I think it should also be valid for RH distros.
According to your /etc/fstab devices /dev/fd0 and /dev/cdrom are mounted at boot with root permissions as indicated by "owner" option. As "owner" in this case is root you cannot mount/unmont them as normal user.
The simplest remedy is you change "owner" with "user" in order you can do such operations as normal user.
I'm a little confused by your question about "ide-scsi emulation"
Is your drive a CDRom or a CDwriter ? If it was a CDRom scsi emulation is not necessary at all and you can remove it from your /etc/lilo.conf file.
You can check what device is using scsi emulation by the command
cdrecord -scanbus (as root) that will return a list, if present, of devices using scsi emulation.
Also remenber to edit your /etc/group file including your logname into "disk" group in order you can use cdrom/dvd drive to listen music/play DVDs as well.
Slackware usually includes only one removable device per bus. You have to add additional devices manually to your /etc/fstab.

Spero che ciò sia stato di qualche aiuto
Ciao

normally you get a different message then..that;s why i'd like to see the out put of the kernel messages.. just to check what the cd drive is

I'm having the same problem as the original poster.

When trying to mount my cdrom drive I recieve the error:
wrong fs type, bad option, bad superblock on /dev/cdrom,
or too many mounted file systems

However, I know that my cdrom is linked to hdb so I'm using the command: mount -t iso9660 -r /dev/hdb /mnt/cdrom

My first inclination is that fstab has /mnt/cdrom already mounting /dev/cdrom but when I just try the mount command on its on, it doesn't show /dev/cdrom being mounted anywhere

Any ideas as to why I'm recieving this error?

I'm just taking a stab in the dark here, but you do have a cd in the drive when you are trying to mount it, right?

As a side note, if it's an audio cd, you don't have to mount it...it will work without mounting (and would give that message if you tried to)...you only need to mount data cds

Jeff

mount will autodetect the filesystem and stuff, so you can just try
mount /dev/hdb /mnt/cdrom
make sure the directory /mnt/cdrom exists
is your cdrom being set up as ide-scsi?
if it is, you need to be mounting as /dev/scd0 probably instead, and
that wont work if you don't have the ide-scsi and sg modules loaded.
you can check with lsmod
cdrecord -scanbus will check for set up scsi drives and emulated drives.

to solve this problem change the fstab entry
to:
btw: with
you can check where /dev/cdrom is really liked to

u mount the cdrom with this command

mount /mnt/cdrom

/dev/cdrom is only the rawdevices

MrP

gee mrpotatohead... you got more than potato in there... or we've got potatos in our eyes

Changing the fstab file to mount from /dev/hdb worked. Thanks guys.

Gonna go read on how fstab works now so I understand why this worked.

sorry to mash yer taters, but you can mount a device by referencing either
its device or its mount point in fstab.

so, with the following entry

/dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0

if fstab was set up correctly, and /dev/cdrom was symlinked correctly
mount /dev/cdrom
or
mount /mnt/cdrom
would work, as would a full specific mount command.

it probably work cos /dev/cdrom is not pointing to /dev/hdb
what does it say when you do this?
should be something like
if(not)
as root;
btw.. i advise you to change your cd to the second ide port (hdc/hdd)... cd roms slow down your hard disk on the same ide port... unless you're using scsi disks

Putting the CDrom drive on the first IDE port was the only way I could get the computer to boot from CD... for whatever reason *shrug*.
