How Do I Fix This Cdrom Error

[cchester]

Hi,

Yesterday I was using my cdrom just fine I was installing a program with Cedega. Now I just did a couple of fixes I had asked about and restarted and now I get this error when I put a CD in.

Here it is:

file:///home/chris/Cd Rom Error.jpg

Just in case it doesn't show the picture it says the following:

Unable to enter file:///media/cdrom0. You don't have access rights to this location.

I didn't change anything so I don't know why it is coming up with this error.

Thanks for any help on this.

Re: How Do I Fix This Cdrom Error

Possible problems:
You aren't a member of the cdrom group.
The fstab line doesn't include the option "user".
The directory's permissions are something like rw-r----- (0640).

Re: How Do I Fix This Cdrom Error

Hi,

I checked and I am a member of the cdrom group.

Also under Disk and Filesystems it is set for any user to mount and unmount.

How to I check or edit the fstab?

Thanks for anymore help.

Here is my mtab:

Also my Fstab:

/dev/sdb1 /media/sdb1 ntfs nls=iso8859-1,umask=000,uid=0,gid=0,auto,ro,users 0 0


Hope this helps from what I can see it looks like the two for some reason don't match as far as the cdrom goes. I could be wrong.

Hope this helps in trying to fix my issue.

Re: How Do I Fix This Cdrom Error

Hmm...
Try changing the "users" options for the CD drive (line 12 in your fstab) to "user". I don't know if it makes a difference, but apparently the option is "user", not "users".

Re: How Do I Fix This Cdrom Error

but apparently the option is "user", not "users"

Both are valid (but slightly different in effect).

@cchester:

What does ls -l /media result in (both with and without a disk "mounted")?

Re: How Do I Fix This Cdrom Error

Hi,

Here is what it said with no cdrom in drive after running ls -l /media.

lrwxrwxrwx 1 root root 6 2007-06-04 06:25 cdrom -> cdrom0
drwxr-xr-x 2 root root 4096 2007-06-04 06:25 cdrom0
lrwxrwxrwx 1 root root 7 2007-06-04 06:25 floppy -> floppy0
drwxr-xr-x 2 root root 4096 2007-06-04 06:25 floppy0
drwxrwxrwx 1 root root 28672 2007-06-11 03:13 hda1
drwxr-xr-x 2 root root 4096 2007-06-06 16:40 hdb1
drwxrwxrwx 1 root root 53248 2007-06-11 03:11 sda1
dr-xr-xr-x 1 root root 61440 2007-06-11 03:11 sdb1
drwxr-xr-x 2 root root 4096 2007-06-06 16:39 sdc1

Here is what it said with a cdrom in the drive after running ls -1 /media.

lrwxrwxrwx 1 root root 6 2007-06-04 06:25 cdrom -> cdrom0
drwx------ 6 400 401 4096 2005-10-13 21:24 cdrom0
lrwxrwxrwx 1 root root 7 2007-06-04 06:25 floppy -> floppy0
drwxr-xr-x 2 root root 4096 2007-06-04 06:25 floppy0
drwxrwxrwx 1 root root 28672 2007-06-11 03:13 hda1
drwxr-xr-x 2 root root 4096 2007-06-06 16:40 hdb1
drwxrwxrwx 1 root root 53248 2007-06-11 03:11 sda1
dr-xr-xr-x 1 root root 61440 2007-06-11 03:11 sdb1
drwxr-xr-x 2 root root 4096 2007-06-06 16:39 sdc1

Looks pretty much the same to me with a few differences but nothing to me that would explain anything.

I am a little of a noob still in some aspects of Linux though.

Thanks for anymore help.

Re: How Do I Fix This Cdrom Error

Looks pretty much the same

No way! - While

drwxr-xr-x  root root  [...]  cdrom0

means that all user are allowed to access the empty folder,

drwx------  400 401  [...]  cdrom0

means that only root is allowed to access the mounted disk

-if at all ... I'm still trying to get the idea behind [UID =] 400 / [GID =] 401

Re: How Do I Fix This Cdrom Error

Hi,

OK so then what should I do to fix this then. That is if I can. I am wanting to burn some things and install some things and I can't. I really need my drive back.

Is my only solution to reinstall?

Or can I copy my files that I don't want to loose to my NTFS data drive that I have or will that mess it up.

I have the drivers installed for it I believe since I can mount them and see them.

Thanks for anymore help.

Re: How Do I Fix This Cdrom Error

what should I do to fix this

Good question - my "best guess" for now:
try to re-set the mount point while in use

sudo chown root:root /media/cdrom0
sudo chmod 777 /media/cdrom0

[cchester]

Re: How Do I Fix This Cdrom Error

Hi,

Ok I tried what you said and this is what I got.

sudo chown root:root /media/cdrom0
chown: changing ownership of `/media/cdrom0': Read-only file system

sudo chmod 777 /media/cdrom0
chmod: changing permissions of `/media/cdrom0': Read-only file system

Don't know if it did anything or not by the replys.

I tried to click on the drive to access the cd and got the same error still.

Ejected and reloaded and still same error.

Thanks for the help. Anymore thoughts?

Re: How Do I Fix This Cdrom Error

Anymore thoughts?

- Try a different disk & try to access it as root (e.g. via [Alt][F2] kdesu konqueror);
- Post the system's feedback to the following commands: groups & ls -al /dev/hd*.

"Plan B":

change the according record in /etc/fstab to

/dev/hdd  /media/cdrom0  udf,iso9660  noauto,users  0  0

- then retry (read: remount) ...

[cchester]

Re: How Do I Fix This Cdrom Error

Hi,

I tried Post the system's feedback to the following commands: groups & ls -al /dev/hd*

This is what I got :

brw-rw---- 1 root disk 3, 0 2007-06-11 18:27 /dev/hda
brw-rw---- 1 root disk 3, 1 2007-06-11 22:27 /dev/hda1
brw-rw---- 1 root disk 3, 64 2007-06-11 18:27 /dev/hdb
brw-rw---- 1 root disk 3, 65 2007-06-11 22:27 /dev/hdb1
brw-rw---- 1 root disk 22, 0 2007-06-11 18:27 /dev/hdc
brw-rw---- 1 root disk 22, 1 2007-06-11 22:28 /dev/hdc1
brw-rw---- 1 root disk 22, 2 2007-06-11 18:27 /dev/hdc2
brw-rw---- 1 root disk 22, 5 2007-06-11 18:27 /dev/hdc5
brw-rw---- 1 root cdrom 22, 64 2007-06-11 18:27 /dev/hdd

Oh by the way when I did Try a different disk & try to access it as root (e.g. via [Alt][F2] kdesu konqueror) I got a blank konqueror window so I did the command in a terminal window.

Plan B I did change the according record in /etc/fstab to /dev/hdd /media/cdrom0 udf,iso9660 noauto,users 0 0.

I get the same error I will reboot and see if it changes anything and post back.

Oh here is my new fstab:

Re: How Do I Fix This Cdrom Error

Hi,

Nope restarting my computer did nothing either.

This is nuts. I don't know how this changed and it seems like it can't be fixed.

The only thing I can think of is I had installed Wine installed one program then this problem started I uninstalled Wine just in case but it did nothing to help either. Wine couldn't have done anything could it?

Do I need to change my /etc/mtab. Are they supposed to match?

Any more thoughts?

Thanks for any more help.
