Automounting CD/DVD combo drive

ErrorBound · 05-23-2006, 08:09 PM

I'm using Kubuntu 5.10 and having issues with a CD/DVD combo drive. After a few hours of googling for a solution, here I am. I can insert a CD and it will mount no problem to /media/cdrom0. If I insert a DVD, Konqueror tries to open /media/cdrom0, but says an error occurred while loading media:/hda, the file or folder does not exist. I can view the files on the DVD by mounting manually (# mount /dev/hda /mnt/dvd). I must manually mount and unmount in order to use a DVD, but not a CD. Is there a way to have both discs automatically mount to the same directory? (preferably /mnt/dvd)

Thanks for any help.

The drive is a Samsung TS-H55U CD/DVD writer.

a dvd should automount to /media/cdrom0 as well.
I take it this CD/DVD drive is in the primary master ide slot? (/dev/hda)

Is this for any dvd or only particular ones?

I think we need to look at /etc/fstab and dmesg | tail (right after dvd media inserted and error message obtained), the exact error message would be nice too.

Thing is, udev should be just getting the command "mount /dev/hda /media/cdrom0" executed when media is inserted. The error seems to be reasonable, /hda certainly dosn't exist.

So the puzzle is: why does udev try to execute "mount /hda (etc)" when a dvd is inserted but get it right when a CD is inserted? Could there be a typo in a config file?

Right.

No this is for any dvd I have tried, both original and ones I have burned myself.

Here is dmesg | tail:

...looking at the fstab I just posted, I notice that there are two entries for /dev/hda. I have tried commenting out one at a time and trying again, but get the same error. Konqueror opens up and tries fo find media:/hda, with the message

Code:

An error occurred while loading media:/hda:
The file or folder media:/hda does not exist.

Simon Bridge · 05-24-2006, 05:37 PM

Well, that last /dev/hda line should be erased. (Keep the /media/cdrom0 line - it is the correct one.) Then reboot. (fstab is read at boot.)

I'm guessing you only got this error after you edited /etc/fstab to include that last line?

ErrorBound · 05-24-2006, 07:13 PM

No, I've always been getting this error. That last line was added by the KDE disk configuration utility when I tried to configure it that way.

Simon Bridge · 05-25-2006, 01:22 AM

OK - the most common cause of this is a typo in /etc/fstab ... however, considering this was happening from scratch, it seems more like a hal/udev type thing.

Looking around, I've found your exact issue in a different context:
