Code: find /lib -name "subfs" /sbin/modprobe -l \| grep subfs The reason for all of the various commands is basically just to get an idea of the "state of things" on your system (with regard to 'udev' and 'subfs'). Some of the commands are a bit redundant, but it's better than doing a "back and forth" - one command at a time - "O.K., now try this" - fourteen times (or whatever)... If you would like more [specific] information about what all this data tells me - let me know... I am thinking you may be missing a kernel module ('subfs', namely). Please see: Code: man submount If the 'find' command (above) yields [something like '/lib/modules///subfs.ko'], you have it. Otherwise, you probably don't... If you don't have it -- try changing these lines in your 'fstab' file: Code: /dev/hdc /media/dvdrecorder subfs noauto,fs=cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8 0 0 /dev/hdd /media/cdrecorder subfs noauto,fs=cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8 0 0 to: Code: /dev/hdc /media/dvdrecorder udf ro,user,noauto,unhide 0 0 /dev/hdd /media/cdrecorder iso9660 ro,user,noauto,unhide,utf8 0 0 With this, you will have to mount and unmount them manually: Code: mount /media/dvdrecorder mount /media/cdrecorder Code: umount /media/dvdrecorder umount /media/cdrecorder __________________ Linux 101 * Linux 102 * Computer 101 * Software 101 * - - Remember: amateurs built the ark... professionals built the Titanic

How could it just disapear? I thought only windoze played such games.

We don't know this, yet. But, I believe the commands at the top of my last post would give us a bit of worthwhile information...

You have to change your 'fstab' file before you try the commands at the bottom of my last post...

Or, you can try "explicit" commands:

Code:

mount -t udf -o ro,user,noauto,unhide /dev/hdc /media/dvdrecorder
mount -t iso9660 -o ro,user,noauto,unhide,utf8 /dev/hdd /media/cdrecorder

Please see:

Code:

man mount

If you don't have it -- try changing these lines in your 'fstab' file:

Code:

/dev/hdc /media/dvdrecorder subfs noauto,fs=cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8 0 0
/dev/hdd /media/cdrecorder subfs noauto,fs=cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8 0 0

to:

Code:

/dev/hdc /media/dvdrecorder udf ro,user,noauto,unhide 0 0
/dev/hdd /media/cdrecorder iso9660 ro,user,noauto,unhide,utf8 0 0

With this, you will have to mount and unmount them manually:

Code:

mount /media/dvdrecorder
mount /media/cdrecorder

Code:

umount /media/dvdrecorder
umount /media/cdrecorder

I came around here, in search of a solution to exactly the same problem. Everytime I update Suse, and I did that a lot from release 8.0 onwards, it appears that they have changed something in the removable disk mounting stuff. Without doing it properly, that is. The lines you gave here just did the trick!
I saw no hurah message from new2nix, so here it is from me.

Thanks a lot!

Because it didn't work for me.

I followed the instructions I was given, so that /etc/fstab now reads ;
/dev/hdc /media/dvdrecorder udf ro,user,noauto,unhide 0 0
/dev/hdd /media/cdrecorder subfs noauto,fs=cdfss,ro,procuid,nosuid,nodev,exec,iocha rset=utf8 0 0

Rebooted (months of reboots), and when running the mount command I was given I still get errors.

>mount /media/dvdrecorder
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

(Root or user. Same result.)

Also, nobody seems to understand that DVD's do play. I watch movies all the time. How is that working if the disk (dvd) isn't mounted? Or maybe I'm just not explaining it enough.

I was not able to view my cddirve, so after some research i appended the following lines to fstab.

Code:

/dev/hdc /media/dvdrecorder udf ro,user,noauto,unhide 0 0 
/dev/hdd /media/cdrecorder iso9660 ro,user,noauto,unhide,utf8 0 0

but then onwards i am not able to login to GNOME at all, even after I deleted those lines, I am still not able to login and getting return to the login Screen.

I am able to login throug "Root" and also able to login to my id from FVWM.

When I am trying to login from KDE, it is giving the following error message:
