CD Drive not being picked up or mounted.

[Ulairi]

Hi,

Bit of a linux novice, used it off and on for a while. Decided to go back to it using suse 10.3. I didn't post on that board because I didn't think it was release specific although I could be wrong.

Since installing it a few days ago I have been unable to access my cd drive at all. I have spent quite a while looking around and have seen similar issues but nothing that corresponds directly or fixes that seem to work.

Here is my /etc/fstab

/dev/disk/by-id/scsi-SATA_IC25N030ATCS04-_CSL309DJJ2P3GA-part1 /                    ext3       acl,user_xattr        1 1

Alot of people seem to list dmesg | tail but mine seems to list nothing pertaining to cddrives only wlan. In my dmesg the only thing I could find relating to my cd drive is

I have also looked through my /dev/ folder and can't seem to find anything linking to my cd-rom.

Any help or advice any one has will be gratefully received.

I haven't used SuSE for a while, but I hope mounting it manually would still work.
In terminal, try:

mkdir /media/cdrom
mount /dev/cdrom /media/cdrom

#or

mount /dev/cdrom0 /media/cdrom


#or

mount /dev/hdb /media/cdrom

[ganeshlinux]

firs use the lsmod command and check whether the cdrom has been detected.....

Thanks for the replies

firs use the lsmod command and check whether the cdrom has been detected.....

I tried to read through it but didn't find anything suggesting that my CD drive had been detected, but then most of it looked like gibberish to me

To Pavio I tried the first method you mentioned just while typing this, I was sure I tried it earlier buy clearly not I seem to now be able to access my cd by navigating to /media/cdrom. Does this then mean that to have it fully functioning under linux I should just add /dev/hdb /media/cdrom udf,iso9660 user,noauto 0 0 to my /etc/fstab and is there anything else I need to change? Thanks alot btw for you suggestion.

Also what I linked from my dmesg is where my boot seems to stall for quite a while. Is this still a problem as by bootup seems to take ages.

Thanks.

Does this then mean that to have it fully functioning under linux I should just add /dev/hdb /media/cdrom udf,iso9660 user,noauto 0 0 to my /etc/fstab ?

Yes, that should be all you need to do.

Sometimes, it may be not /dev/hdb. To find out which /dev/... to use in /etc/fstab, mount CD manually (mount /dev/cdrom /media/cdrom), and then type:

mount

in the output, look for line which represents mounted CD. If it shows:

/dev/hdb on /media/cdrom type iso9660 (ro)

then use /dev/hdb in the /etc/fstab.

Thanks so much, put an end to my first headache of the re-linuxing
