mounting a cdrom drive

johnvillegas · 03-10-2006, 06:25 PM

I tried to mount my cdrom drive, but I got a message saying that the cdrom type is not supported by my kernel. What am I doing wrong? What should I do?

Can you post the results of 'lspci' and the exact error you receive?

It may come down to the dreaded (Insert ominous music clip here) KERNEL RECONFIG! (Dun dun dun).

The following message is the error message I get when I try to mount the cd-rom drive:

bash-2.05b# mount /cd
mount: can't find /cd in /etc/fstab or /etc/mtab

OK....I see

Try (as root or su)

Code:

mkdir /cd
mount /dev/hdc /cd #Change /dev/hdc to your cdrom device
# Am assuming /dev/hdc due to this being a laptop...

It seems you have no /cd directory on your HDD.

(Note: Don't type in the '#' comments. They are just there to help you.

#mount /dev/cdrom

will also work. No need to specify the destination as its specified in /etc/fstab ( by default ).
It will mount on the default directory ( /mnt/cdrom )

Also, what is the output from

Code:

cdrecord -scanbus

Lastly, do you have a data CD in the drive? Note that you can't mount an empty drive or an audio CD

johnvillegas:
As 'ruudra' said, slackware by default puts an entry in /etc/fstab for your cdrom device, and creates a symlink to it named /dev/cdrom. Hence, typing the following command should mound the CD drive:

Code:

mount /dev/cdrom

there is no command like this
the command is "mount /mnt/cdrom "(hope u have a fstab entry pointing towards /mnt/cdrom)

edit the fstab like this for user to mount cd(supposing ur device is /dev/hdc-if u have a link like /dev/cdrom, then use that, instead of /dev/hdc)
/dev/hdc /mnt/cdrom auto noauto,user,ro 0 0

----comments----
or if he want to mount it to /cd, much problems ahead
as cwwilson said "mount /dev/hdc /cd" u wil get error emssage, u need to type file system type, the command is "mount -t iso9660 /dev/hdc /cd"(after creating dir)

if he want to use the command "mount /cd" edit the fstab
like
"/dev/cdrom /cd auto noauto,user,ro 0 0"
i think at this point, he dont need any "/" before cd tht is "mount cd" will work

if u want to try command by rudra "#mount /dev/cdrom" u must need a simlink in dev dir pointing to cdrom device (here we assigned as /dev/hdc)in general slack will create a link in default(for security reasons) and use tht in fstab. here we are directly calling the cd device, i hope best choise is mount to the mount point

but if u have 2 cd devices u haev to manually create link and edit the fstab entry, slack wont show the 2nd cd device

(hope u have a link /dev/cdrom exists, if u want to know the device try "ls -al /dev/cdrom", or check the out put of "dmesg |more" or "dmesg |grep CD")

You are right. I just got off of driving in my job for 16hrs...I was a little tired. Forgot to do the '-t iso9660' part. My biggist apologies

me too made many mistake when i post first reply(#8) "mixed both fstab entry and mount command" but i soon editted,(before someone pointing) this was too simple and we do this all the time (mounting ), and i took it for granted

evenif i am not 100%sure i wil post teh replys, thinkig others in this forum wil correct it
