I put a CD in the BenQ and did exactly what you suggested.


[nissanka@c83-250-90-204 nissanka]$ su root

[root@c83-250-90-204 nissanka]# mount /dev/hdc /mnt/cdrom
mount: block device /dev/hdc is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
or too many mounted file systems
[root@c83-250-90-204 nissanka]#
----------------------------------------------------------------------------------------------------------------------------

Here is the output of the other command

'[root@c83-250-90-204 nissanka]# ls -l /dev/cdrom
lr-xr-xr-x 1 root root 13 okt 13 13:15 /dev/cdrom -> cdroms/cdrom0
[root@c83-250-90-204 nissanka]# ls -l /dev/cdrom
-----------------------------------------------------------------------------------------------------------

I repeated the above without logging on as a root user. Please read the following:


[nissanka@c83-250-90-204 nissanka]$ ls -l /dev/cdrom
lr-xr-xr-x 1 root root 13 okt 13 13:15 /dev/cdrom -> cdroms/cdrom0
[nissanka@c83-250-90-204 nissanka]$

post the contents of please

Here it is.

By the way, those hda9, hda10 and hda11 belong to Linux.

Those hda2, hda5 are Windows XP partitions. Don't care about them. I am not interested in them.

Now I will leave for the gym and will be away for a few hours.

I deeply appreciate your help. Leave your messages. I will attend them as soon as possible.

I am in Europe. Are you based in the USA or in Europe?

What shall I do now? Please tell me.


I badly need your help.

cat /proc/cpuinfo

Thanks IOerror

My urgent requirement is to fix the problem. I can't mount the CDs. Please tell me how to solve the problem.


The following is the outpput:

A Celeron is IA32.

As for the CD, hmm, you say you can boot from it, so it obviously works?

What boot parameters are you using? If you're using ide-scsi (although that should be mentioned in dmesg I think), then /dev/cdrom should be pointing to a SCSI device such as /dev/sr0 (though it looks like you're using devfs, so it'll be something different).

Thanks Ioerror

I have already posted the message from 'dmesg' command. You could read it. I am clueless about the message from this 'dmseg' command.

Ok, try this. Put your CD in the samsung and just issue a Oh, and remember we are all volunteers, you don't have a right to recieve our help - it is a privalege. Most of us have lifes outside of LQ that need attending to every now and again, so bear that in mind when bumping your thread after only two hours

The Samsung gave the following:
[root@c83-250-90-204 nissanka]# mount /mnt/cdrom
mount: No medium found
[root@c83-250-90-204 nissanka]#

---------------------------------------------------------------------------------------
The BenQ gave the following:

[root@c83-250-90-204 nissanka]# mount /mnt/cdrom
/dev/hdd: Input/output error
mount: /dev/hdd: can't read superblock
[root@c83-250-90-204 nissanka]#

Oh, nevermind, I'm being silly.

Copy /etc/fstab to your home dir so you have a backup, then edit this line:
so that it reads
save it, then put your CD in the benQ drive and try /mnt/cdrom points to your BenQ drive, we'll worry about the samsung one later on

This is how it looks like.

I will edit it as you have suggested.

I edit it. Now it is as follows:

[root@c83-250-90-204 etc]# vi fstab
[root@c83-250-90-204 etc]# cat fstab
/dev/hda9 / ext2 defaults 1 1

It seems the CD has gone to hell. The following is the output.
