I have lost my optical drives!

After a complete system update via smart, I seem to have lost my optical drives in SuSE. The BIOS recognizes then, and I can boot from them, yet they have gone missing from my Fstab. Here's my current Fstab if it helps;

Quote:

/dev/sda6 / reiserfs acl,user_xattr 1 1
/dev/sda7 /home reiserfs defaults 1 2
/dev/sda1 /home/Windows/C ntfs ro,users,gid=users,umask=0
/dev/hdc5 /home/Windows/D ntfs ro,users,gid=users,umask=0
/dev/sda5 swap swap defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs noauto 0 0
debugfs /sys/kernel/debug debugfs noauto 0 0
usbfs /proc/bus/usb usbfs noauto 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0

Fdisk doesn't return anything better;

I have no idea what to do. Any ideas?

Shot in the dark:

$mount -t iso9660 /dev/cdrom /<mount-point>

I've never used Suse at all, but Redhat seemed to do the same thing to me once. I tried looking for the device file name for the cdrom and couldn't find any references to it anywhere. So, I went and dug around my old notes and came across the reference to /dev/cdrom. I tried it and it worked. Go Fish.

Is smart a bios update? Have you refreshed your bios setup already? like loading its default settings?

What does "dmesg | grep -i atapi" output?

Those are the drives, now how do I add them to fstab? Thanks a lot!

Use the editor of your choice (vi, vim, pico, nano) and issue as root in a terminal:

Code:

pico /etc/fstab

and then add these three lines:

Code:

/dev/cdrom       /mnt/cdrom       auto        noauto,users,ro  0   0
/dev/hda         /dvd             auto        noauto,users,ro  0   0
/dev/hdb         /cdrw            auto        noauto,users,ro  0   0

This will allow you to mount your drives as a normal user. However, you must create the mount points "dvd" and "cdrw" (or use ones previously created).

I also change owner to my regular user, and change mode to 755 by issuing:

Code:

chown mingdao.users /dvd
chmod 755 /dvd
chown mingdao.users /cdrw
chmod 755 /cdrw

After that, make sure you have the symlink to /mnt/cdrom by issuing:

Code:

mingdao@silas:~$ ls -lh /dev/cdrom
lrwxrwxrwx 1 root root 3 2006-09-30 13:19 /dev/cdrom -> hdc

Slackware creates that link for me and has these permissions:

Code:

mingdao@silas:~$ ls -alh /dev/hdc
brw-rw---- 1 root cdrom 22, 0 2006-09-30 13:19 /dev/hdc

Substitute your username for mingdao.

After it's all setup, you may need to run "xine-config" in a terminal, and if you use K3B you might need to run it's setup program again, also.

Zedd129,

Were you able to successfully add your drives?

You should post back to threads you start and tell what you
did to solve your problem. That way others who search and
find your thread will know the solution.
