new dvd rom doesnt work?

Asked by walksponsored

I just took out my old dvd rom and put a new dvd burner in its place and now it doesn't read when i put anything in the drive? When i click on the "cd rom 1" icon in "computer" it says unable to mount volume: special device /dev/hdd does not exist, i do not know how to install this new piece of hardware onto my pc and it worked on my old windows pc immediately when i put it in the computer.

Can you please try the following:

1. Run the command sudo /etc/init.d/dbus restart
2. Log off.
3. Log back in and check your "Computer" icon to see if it picked up your new DVD burner.

If the above doesn't help, can you please paste the contents of your /etc/fstab file, as well as the output of the command(s):

grep -i dvd /var/log/dmesg
or
grep -i cd /var/log/dmesg

Try the first one at first, you should see something like this:
[ 5.859699] hda: PHILIPS DVD+/-RW DVD8631, ATAPI CD/DVD-ROM drive
[ 7.098814] hda: ATAPI 40X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache, UDMA(33)
which makes it clear that my DVD burner is in fact /dev/hda. Basically what I'd like to know is what device name has been assigned to your DVD burner.

Also, if you can tell me what IDE (or SATA) bus the DVD burner is hooked up to, that would be great. For example, is it a primary slave on the IDE bus?

Thanks!

hello all, I am having the same problem. Rouben, I took your advice and used the above commands in a terminal window, and still no luck. So i used the grep -i dvd /var/log/dmesg command and here are the results. P.S. The DVD drive is an LG Burner plugged into the SATA port on my mobo.

james@james-desktop:~ $ grep -i dvd /var/log/dmesg
[ 4.076000] hdb: CR-487ETE, ATAPI CD/DVD-ROM drive
[ 5.656000] scsi 1:0:0:0: CD-ROM HL-DT-ST DVDRAM GH20NS15 IL00 PQ: 0 ANSI: 5
[ 6.304000] sda:sr0: scsi3-mmc drive: 78x/78x writer dvd-ram cd/rw xa/form2 cdda tray

Hmmm that's weird, that looks just fine... Can you also post the
contents of your /etc/fstab file (you can do "cat /etc/fstab" on the
command line and paste the output here, or better yet on pastebin.com;
it's easier to read).

Check the pastebin again (my second post, I messed up my first one). Basically try changing the /dev/hda line that refers to your CD-ROM from /dev/hda to /dev/scd0. If that doesn't work, try /dev/sr0 (they should be the same file anyway). You may have to restart for the GUI to detect this change. Let me know how it goes.

Using pastebin in this thread was no useful for other user... with same problem.
Please also copy and paste your messages or solution here.

Thank you.

marcobra: I thought of doing that, but from my experience pasting things like config files (especially tab-based) on here messes them up and makes them hard to read. Pastebin, on the other hand makes it really easy to exchange files like that and even highlight things you want to focus on. I think Launchpad should have its own Pastebin instance, or include that functionality in the bug tracker and answer modules... maybe I'll suggest that to the Launchpad dev team. :)

James: sudo gedit /etc/fstab ought to bring up an editor with the file. Use it just like any other text editor... /etc/fstab is just a text file. :)
