after upgrading from 7.10 to 8.04 cdrom won't mount

[Mit]

Ok I've recently upgraded from 7.10 to 8.04, and been upgrading my debs on a daily bases. Hoping a fix would come in. Since the upgrade I haven't been able to mount my cdrom drives. when ever I issue the command mount /media/cdrom0 I get this error message:

mount: block device /dev/scd0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so

and when I run dmesg | tail I get:

[ 8610.000557] end_request: I/O error, dev sr0, sector 629592

Hi,

I got the same problem in my friend's laptop upgrading from 7.10 to 8.04. Also, my friend lost it's NTFS partition (it became in FAT32). After two days probing utilities from UBCD I got to restore the NTFS partition and see the files inside but he can't boot on windows anymore.

Some info:

Hi,

I'm having exactly the same problem. This is a serious bug, it makes my dvd drive completly useless!

My DVD driver doesn't read video DVDs, it reads Audio CDs with lot of noise in the sound and mouting data cd/dvd fails with this message.

**********************************************************
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so.
**********************************************************

I think this is a kernel related issue.

I'm attaching this files:
      uname -a > uname-a.log
      cat /proc/version_signature > version.log
      dmesg > dmesg.log
      sudo lspci -vvnn > lspci-vvnn.log

[AnGus (ozsolarwind)]

I've installed recent updates and the problem has 'gone away'.

[Rui Castro (rui.castro)]

Hi,

the most recent updates did nothing for me.
My cdrom drive is still completely broken.

[Tomás Vírseda García (kaskaras)]

Hi,

Finally, I downloaded another Ubuntu 8.04 iso image and I did a fresh install deleting all partitions and reinstalling again. Mostly, everything is working fine but sometimes when I boot the computer, the progress bar is stopped until I switch to a terminal. It keeps waiting for something related with the device (sorry, but I couldn't get those data from my friend laptop. I think to remember that is something related with the UDMA but not sure).

It only happens at the beginning. Once logged in everything is working fine.

Thanks ands regards

[Tomás Vírseda García (kaskaras)]

I think this is my last comment about this bug because with the next upgrades everything is OK. If more info is needed don't hesitate to contact me.

Thanks again and regards

[Rui Castro (rui.castro)]

Hi,

The last updates did nothing for me.
Audio CDs play with lots of noise and DVD Video mounts and shows only the audio_ts directory (no video_ts)
the dmesg output is a list of lines like these

Guess I'm finally getting around to joining this discussion. If anyone has this now working on their system, could you please share what you have in /etc/fstab in relation to your cd-rom(s)?

I am getting error like this in both Intrepid and Jaunty. (This taken from the Intrepid dmesg log)

Here's the cdrom lines from my fstab:

/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0
/dev/scd1 /media/cdrom1 udf,iso9660 user,noauto 0 0

Any suggestions are appreciated.

Update on CD issues.

Ok over New Years I installed 8.04 on a complete new machine at my parents place (this machine has never run linux before just windows). that happens to be the same make and computer that i have at home. a Dell Dimension 4700, both with factory defaults. after I finished the install I made sure I upgraded all the packages with the latest releases. and low and behold, the CDROM still wont allow me to rip and/or play Audio CDs. It's able to read the Track List in the audio player supplied with ubuntu, but that is it. Same as the issue on my machine I had originally upgrade from 7.10. I didn't try mounting any CDs since the Audio CD portion still wasn't working, thus I assumed that mounting didn't work either as before. I can try that the next time I'm at my parents place and report back.

.....Same problems for my system!
.......I found that by running- sudo mke2fs -j /dev/sdb1- in terminal will get my cd rom to work until the program finishes running.This problem has something to do with the inode tables I do believe.
