Its just when I mount the cd it always says its busy if there is something in the dvd drive. and I can see the contents of the dvd through the cdrom. I was told I have a symlink problem. Any help is appreciated.

You can see this content of your DVD from the /mnt/cdrom directory ,i don't remember now can you check the content of your fstab
/dev/dvd /mnt/cdrom , if it like this so cdrom directory supposed to read the dvd device ,one other idea go to /dev/ and see if something like
cdrom -> dvd (symlink) .
try also to unmount the dvd and the cdrom and after mount your cdrom when there is no dvd inside the dvd rom (your dvd is RW).

tell me about any news

hope this help

If I am at the command line, i type mount /dev/cdrom, it mounts the dvd. If i then type mount dvd it says its already mounted. Here is fstab: Code: /dev/hda1 swap swap defaults 0 0 /dev/hda2 / reiserfs defaults 1 1 /dev/hda3 /usr reiserfs defaults 1 2 /dev/hda4 /home reiserfs defaults 1 2 /dev/dvd /mnt/dvd auto noauto,users,ro 0 0 /dev/cdrom /mnt/cdrom auto noauto,users,rw 0 0 /dev/sda1 /mnt/flash vfat noauto,users,rw,exec,umask=000 0 0 /dev/fd0 /mnt/floppy auto noauto,owner 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 proc /proc proc defaults 0 0 if I go to /dev/ i dont see anything that says symlink or anything, but if i click on the properties of dvd, and cdrom, they both point to /dev/hdc

Every combination not working. --------EDIT-------------------------------------------------------------------------------------------------------------------- Problem solved on another forum, here is the link: http://www.linuxquestions.org/questi...91#post2645991 Thanks aloiv for your help.

I did notice however that if I clicked on properties of both of them in Konqueror they both said they pointed to /hdc. I had to reboot before the new symlinks worked. I did NOT reboot after i edited the fstab. Maybe that was my problem. I will try it to se if it works, I would like to know as well.

You were right aloiv, all i needed to do was edit fstab. No reboot required.

I think the problem was that I had bad symlinks to start with, and all I needed to do was remove them, then edit the fstab.

Here is what fstab looks like now:

Code:

/dev/hda1        swap             swap        defaults         0   0
/dev/hda2        /                reiserfs    defaults         1   1
/dev/hda3        /usr             reiserfs    defaults         1   2
/dev/hda4        /home            reiserfs    defaults         1   2
/dev/hdc      /mnt/dvd         auto        noauto,users,ro  0   0
/dev/hdd    /mnt/cdrom       auto        noauto,users,rw  0   0
/dev/sda1        /mnt/flash       vfat        noauto,users,rw,exec,umask=000  0   0
/dev/fd0         /mnt/floppy      auto        noauto,owner     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0
