Cannot mount CDROM DVD drives after upgrading to Ubuntu 10.04 LTS Lucid Lynx

[jorisbots]

As suggested, I have changed the boot order in BIOS to boot from hard drive first. Now CD is detected also if no CD was inserted during startup.

Thanks for that tip!

This worked form me to! I have two harddrives. After changing the order to HD1 - DVD - HD2 it worked. HD1 - HD2 - DVD did not work.

I don't know how it works, i'm a newbie. But after searching the web, i came across someone suggesting to disable the cd at bios. What I did was to change the boot order of my devices in bios to boot on HDD first then CD. After that upon login to ubuntu, bang, everything works perfect. The CD/DVD drive was back to normal... hope it helps. CHeers.

This fix worked for me as well. My CDROM drives stopped auto-mounting after the upgrade to 10.04.

My drive is still not being mounted.

Please help..

It worked at first and it seems an update ruined it or sth..

Thx

Having the same issue. changing boot order in BIOS had no effect whatsoever. Nothing will automount. USB driver, External hard driver or CD/DVD... have tried all manner of things suggested on various posts, yet to find a solution....peeeved

In my case this heps:
1. make link from /cdrom to /media
(sudo ln -s /cdrom/ /media/)
2. add line like this in /etc/fstab
(/dev/sr0 /media/cdrom udf,iso9660 user,noauto 0 0)
3. reboot your computer, rest ubuntu fix self

have exactly the same problem, tried all of the suggestions without luck. Also can't mount external usb DVD-ROM.

I am pretty sure I have used the drive to burn a CDR without a problem

Here is the error I get:

root@adrian-laptop:~# mount /dev/cdrom
mount: block device /dev/sr0 is write-protected, mounting read-only

       In some cases useful info is found in syslog - try

Here's the fstab:

here's the entry in the syslog for a single mount attempt:

I have been having the same problem as described above: Put a CD (or DVD) into the drive, the lights blink as expected, but /var/log/messages has no information about it, no mount line appears in /etc/fstab, hdparm knows nothing about /dev/sr0, all mount attempts fail.

I tried one of the suggestions above: Booting the machine with a blank disk in the drive. After that it worked as expected: I could put a disk with content in the drive and the system would find it.

Then I rebooted again, with no CD in the drive. After reboot, CD mounting still worked as it should. Will it continue to work? I don't know yet.

I think BarryDock is describing a different problem. If his mount attempt gets so far as to complain about the filesystem type it is getting further than my mount attempt did. If I put a blank CD into a properly-working drive and do
mount -t iso9660 /dev/sr0 /mnt/cdrom
Then I get exactly the error messages he quotes above.

Still haven't completely solved the problem, but the following seemed to have had a beneficial effect in my case:

1. From the Ubuntu menu bar I launched
System > Adminstration > MountManager

2. MountManager indicates my two CD/DVD drives as "sr0" and "sr1" respectively.

3. The entry "Mount point" was blank for both sr0 and sr1.

4. So I selected as mount points my exisiting directories "/media/cdrom0" and "/media/crdom1"

5. Rebooting Ubuntu then gives two error messages saying something about being unable to mount "/media/cdrom0" and "/media/cdrom1". Never mind. I enter "S" for skip twice.

6. Once Ubuntu has been completely booted, disks are automatically mounted upon inserting them in the drives, including when no disk was inserted during boot.

Any further help with this one?

It seems we are not the only ones struggling:

I may have a partial answer. I was getting similar problems with access to cd drives after an upgrade to Lucid.

Under Hardy, I would copy cds using cdrdao, with a command such as this:

$ sudo cdrdao copy --force --source-device /dev/<xxx> --device /dev/<xxx>

Where "xxx" stands for the letters and numbers that worked under Hardy.

With any attempt to access a cd drive, I was getting the "special device /dev/hdd does not exist" message.

Using System->Administration->DiskUtility, I could see that the system did recognize my drives under different device names. Using the new letters and numbers visible in DiscUtility makes the command work:

$ sudo cdrdao copy --force --source-device /dev/sr0 --device /dev/sr1

If you don't have DiskUtility, it's listed as gnome-disk-utility in Synaptic Package Manager. It's also known as "palimpsest."
