mount: input/output error?
 

hi there:

i have been trying to mount my cdrom but for somereason i could not get it to work. in my /etc/fstab, i have

/dev/cdroms/cdrom0 /mnt/cdrom auto noauto,user 0 0

and when i try

mount /dev/cdroms/cdrom0

i got
/dev/cdroms/cdrom0: Input/output error

can anyone help?

many thanks

ps, i have got the feeling that the cd drive driver might not have been installed configured properly. is there any command to see if its on the system?

Are you sure that /dev/cdroms/cdrom0 is the proper device?

(Also, Fedora usually configures the CDRom properly in fstab)

As far as mounting is concerned, try "mount -a" Or try this:
"mount -t iso9660 /dev/cdroms/cdrom0 /mnt/cdrom"

thanks for your reply!

oops, forgot to say that i am trying out Gentoo, so this is for Gentoo.

i set up my fstab according to this:

http://www.gentoo.org/doc/en/handboo...?part=1&chap=8

and

mount -t iso9660 /dev/cdroms/cdrom0 /mnt/cdrom

i got

mount: block device /dev/cdroms/cdrom0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/cdroms/cdrom0, or too many mounted file systems

mount -a

does not give me anything.....


cheers

I thought of testing out the command that I gave you. So I put in a blank CD in my drive and I got the same error that you got!!

Then I put in a proper CD and mounted, and it worked

So you aren't using a blank CD to test this out, right? Also, I'll explain what this command does:

Here, the "-t" specifies the filesystem type. It can be anything from vfat to ext3 to iso9660. CDs use iso9660 mostly. Instead you can also specify "auto" So the command will be
The error you got: "wrong fs type" was concerning the filesystem. Try using "auto". And don't use a blank CD, since it has no filesystem created on it. Also, if you post your /etc/fstab here, it will help.

thanks for you reply!

i have also tried


and i got

and its not blank cd, i use a audio cd to test.

my fstab looks like this


/dev/hda1 /boot ext2 defaults,noatime 1 2
/dev/hda2 none swap sw 0 0
/dev/hda3 / ext3 noatime 0 1
/dev/cdroms/cdrom0 /mnt/cdrom auto noauto,user 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs nodev,nosuid,noexec 0 0

This is the line in my fstab concerning the cdrom:

Change the /dev/scd0 to your device, /dev/cdroms/cdrom0 and try if it works. Remember to make a backup.
