can't mount a dvd on a cd burner/dvd rom drive

dr_zayus69 · 12-01-2004, 09:25 PM

i have a combo cd burner/dvd rom drive. I tried to mount a dvd in it but it said no meda found. Is there a way to configure to be able to read both cds and dvds? Im guessing it involves fstab.

I also have a CD-RW/DVD Combo drive and I just have a normal fstab entry for it.
/dev/cdrom /cd0 iso9660 noauto,user,ro 0 0

i haven't edited the fstab before, is there a good tutorial about doing so? i don't want to mess with it and possibly screw it up.

first thing post your fstab, maybe you need to fix only one thing...

it's very easy to edit that file, there is nothing really complex in it, follow these steps as root:

1. make a new folder like /mnt/dvd or /mount/dvd or /dvd, depending on your system. it doesn't really matter by what name and where you create it. now i'll assume you created /mount/dvd just to make things clear.
2. with a text editor (like kedit or gedit) open /etc/fstab, it will look something like

Code:

/dev/hda5        swap             swap        defaults         0   0
/dev/hda6        /                reiserfs    defaults         1   1
/dev/hda7        /home            reiserfs    defaults         1   2
/dev/hda2        /win             vfat        auto,gid=100,uid=500,rw         1   0
/dev/hdc         /mnt/cdrom       iso9660     noauto,user,rw   0   0
/dev/fd0         /mnt/floppy      auto        noauto,owner     0   0
/dev/sda1        /mnt/camera      vfat        noauto,user,rw   0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0

3. add at the end of the file this line:

Code:

/dev/hdc     /mount/dvd     iso9660     noauto,user,ro     0     0

4. save the file and just type (also as user) mount /dev/hdc to mount your dvd!

note that if you want to write your dvds then you'll have to write rw instead of ro in your fstab

this is my fstab

LABEL=/ / ext3 defaults 1 1
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
/dev/hda6 swap swap defaults 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/cdrom1 /mnt/cdrom1 udf,iso9660 noauto,owner,kudzu,ro 0 0

when you are creating the /mnt/dvd folder then editing the fstab to reference it is that creating a symbolic link or am i mistaken?

thats not creating a symlink, you are just telling the mount command where to mount the filesystem.

Your /dev/cdrom is most likely a symlink to a block device. If you type ls -l /dev/cdrom you will see what device is your cdrom:

Code:

ls -l /dev/dvd

lrwxrwxrwx  1 root root 3 2004-07-07 00:27 /dev/dvd -> hdb

Try changing your fstab entry to auto or just iso9660, e.g.

/dev/cdrom /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0
or
/dev/cdrom /mnt/cdrom auto noauto,owner,kudzu,ro 0 0

lrwxrwxrwx 1 root root 10 Oct 16 00:12 /dev/dvd -> /dev/cdrom

that is what i get when i do ls -l /dev/dvd
