      Forum software upgrade   10/29/17

      So you may have noticed the forum software has upgraded !!!
      A few things that have changed. We no longer have community blogs (was never really used) We no longer have a portal page.
      We can discuss this, and decide whether it is needed (It costs money) See this thread: Here

Laptop dvd drives won't mount [solved]

Recommended Posts

I have an HP Omnibook vt6200 with several drive modules: a cdrw drive, a single-layer dvd, and a double-layer dvdrw. I managed to install Mandriva Powerpack 2008 on it with the dvd drive in the slot, but since then I cannot get Mandriva to recognize either of my dvd drives. The laptop powers the dvd drives and spins discs, but they won't mount. The cdrw seems to work fine. Any suggestions?

If it's DVD's then install the libdvdcss packages to read movie DVD's. If they are just data DVD's then they should mount fine normally. Otherwise, please post the results from an:




so we can see your hardware installed and go from there, as well as:


dmesg | grep -i cd

I assume that the CDRW is the "main" drive in the OmniBook?


My experience is that the main drive is the one that the OS will link the mountable directories to. What I mean is that the CDRW is likely found at /dev/hda or /dev/hdc whereas the DVD drives follows as /dev/hdd or /dev/hde. Most automount utilities or applications will mount the "premier" drive to the /dev/dvd or /dev/cdrom devices. This means that everytime you want to access these devices the PC will almost always go directly to your CDRW.


You can modify your /etc/fstab file to point the mount point to your desired optical drive, or you can point the "generic" device name to the device you want. This can be done by something like:


umount /dev/dvd (unmounts old device)

ln -sf /dev/hdd /dev/dvd (links your desired dvd device to the generic dvd device link)



Hope this helps.

There are absolutely no fstab entries needed for removable devices anymore... hal will take care of all of them (under /media). Only legacy/ancient applications and a few emulators (like wine) will need these entries.

Whenever you insert a medium, blank or not, the DE notification daemon will popup a warning, and you can pick your action (normally mounting the medium). Since audioCD's are not mountable, you can only mount them using a virtual filesystem, but for all other disk types (coasters excluded) mounting just by having hal running and its rules not screwed is entirely possible.

When you say you have three drive modules you mean hot-swappable ones, which mount in the same laptop bay?

These are with the DVD module installed in the laptop. I installed the latest version of openSUSE, and this read the drives without problems. I would prefer to get Mandriva working though. I am running Mandriva Powerpack 2008.0.

It looks like the DVD drive is /dev/hdc. So what you could do is put a CD/DVD in the drive, and then you could do:


mkdir /mnt/cdrom
mount /dev/hdc /mnt/cdrom


and then take a look in /mnt/cdrom to see if any files are listed. If so, then it's mountable OK, and it's just not auto-mounting properly.

Many thanks to the advice so far, but since I had nothing really invested in the Powerpack installation I downloaded and installed Mandriva Spring 2008.1. All drives seem to work now. So my problem is solved, but I do wonder about my Powerpack 2008.0 version. I have it running on several machines with no problems. Anyway, thanks again all.
