Hello everone, recently I installed suse 10.2 on my computer. Looks good! The only problem I have is the following:
Reading a dvd in my Plextor PX-712A does not work?
Starting my computer and booting with a DVD works, but when I insert the same dvd after starting the pc I cannot read this dvd. The effect with other dvd's.

/etc/mtab:
/dev/hda1 / ext3 rw,acl,user_xattr 0 0
proc /proc proc rw 0 0
sysfs /sys sysfs rw 0 0
debugfs /sys/kernel/debug debugfs rw 0 0
udev /dev tmpfs rw 0 0
devpts /dev/pts devpts rw,mode=0620,gid=5 0 0
/dev/hda6 /home ext3 rw,acl,user_xattr 0 0
securityfs /sys/kernel/security securityfs rw 0 0

/etc/fstab:
/dev/hda1 / ext3 acl,user_xattr 1 1
/dev/hda6 /home ext3 acl,user_xattr 1 2
/dev/hda5 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
/dev/fd0 /media/floppy auto noauto,user,sync 0 0

Both file's listed above have something to do with mounting?
The floppy drive is mentioned in fstab, but the cdrom drive not?
Has it something to do with drivers?
Who can help?
Thanks in advance.
greetings Ed

Hope the information below helps. Also make sure your user is part of the CDROM security group if they are not add them. I would get it working with your root users first and then get it working with your users to simplify things.

Most Linux distributions do not allow users to mount the CDROM drive for security reasons. Root access is usually required to do so. However, someone with root access can allow users to mount the CDROM using the /etc/fstab configuration file.

Example /etc/fstab without user privileges to mount the CDROM:


/dev/hda1 / ext2 defaults 1 1
/dev/hda5 swap swap defaults 0 0
/dev/fd0 /mnt/floppy ext2 noauto 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,ro 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0



Example /etc/fstab with user privileges to mount the CDROM:


/dev/hda1 / ext2 defaults 1 1
/dev/hda5 swap swap defaults 0 0
/dev/fd0 /mnt/floppy ext2 noauto 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,ro,users 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0


Notice the users tag in the fourth column of the line beginning with /dev/cdrom. This allows anyone in the users group to mount the CDROM using the iso9960 filesystem with the command mount /mnt/cdrom.
You can also add individual user names to the end of the fourth column to give them only certain users access.

Thanks for your reply. I will try your suggestions. But I have some further information.
Yesterday I found out that I can read the dvd when I first insert a cd and than the dvd?? Very strange to me. But maybe this helps?

Thank you for the suggestion, Rustylinux. Adding the cdrom group to a computer solved the problem I was having with it. Interestingly, only one of the two computers at our house running openSUSE 10.2 had this problem. The other accessed DVDs fine without needing this permission . . . and I thought that both were set up the same.
