Can't read DVDs/CDs in Mandriva 2006


Hello,

i recently updated from Madrake 10.1 to Mandriva 2006.

Now i have a big problem: My DVD-ROM drive can't read DVDs or CDs anymore.
Everytime i put a DVD in, the disk icon appears on the desktop (just like usual). When i click on it, i get an error, something like
"burn:/// could not be displayed"
(had to translate it myself, so might be not 100% correct.)

When i put a CD in, sometimes the same happens. Sometimes it works all fine, and sometimes the whole Madriva crashes, so i only can press the reset button.

I already tried unplugging it, boot up without it, shut down, plug it on again and let mandriva reconfigure it. But did not help.

Whats wrong? Something with the mount parameters maybe?

It could possibly be a problem with the mount parameters. Being used to slackware with manual mounting, I don't know the exact method, but attmept to shut off the automout and then try the following:

mount -t iso9660 /dev/hdb /mnt/cdrom (substitute hdb with whatever ide channel its on [a-d, usually a is your hard drive])

If that works then possibly the automount is wonky...

Thanks for the input.
I will try that out as soon as my neighbor gets home from vacations (it is his pc which has the problem) and report back.

So, referring to the hd* thingy:

Does it work like that?:

a = Primary Master
b = Primary Slave
c = Secondary Master
d = Secondary Slave

Or is this totally wrong?

no, that's correct. You may also just have a link as /dev/cdrom or /dev/dvd, but if you look at it (ls -lag /dev/cdrom) it usually is just a symlink to /dev/hdb.

Post what's in your /etc/fstab and the output of the mount command when you have a CD or DVD in there.

Ok, i wasnt able to try the manual mount yet, but here is the fstab file, maybe it helps:

# This file is edited by fstab-sync - see 'man fstab-sync' for details
/dev/hda1 / ext3 defaults 1 1 none /dev/pts devpts mode=0620 0 0 /dev/hda6 /home ext3 defaults 1 2 /dev/hdc /mnt/cdrom auto umask=0,user,iocharset=iso8859-15,sync,unhide,codepage=850,ro,users 0 0 none /mnt/floppy supermount dev=/dev/fd0,fs=ext2:vfat,--,umask=0,iocharset=iso8859-15,sync,codepage=850 0 0 none /proc proc defaults 0 0 /dev/hda5 swap swap defaults 0 0


I am also a bit worried about the error message

">>burn:///<< could not be displayed"

I dont have a writer, only a DVD-Rom.

Thanks,
rag

Hi,

i finally used your hints.
The status is the following:

-I disabled Supermount.

-Now CDs work just fine! I put them in, the CD icon appears on the desktop and when i click on the icon a new window opens where i can browse the cd.

-When i put a DVD in, the DVD icon appears on the desktop. When i click on it, the following error appears: "There is no default action linked with this storage location" (or something like that, had to translate it myself). When i access the DVD with the File Explorer or via console, it works fine and i can even play the DVD movie if i manually open the vob files. So there seems to be no action linked with the icon on the desktop right?

So there is one matter left: How can I assign an action to the icon on the desktop? (for example it should start the Totem Video player)

Thanks alot!

How did you update? Did you choose that option at the start of the install?

I have tried this kind of update several times 8 to 9, 9 to 10 and recently 2005 to 2006.

I have always had serious problems afterwards and strongly recommend choosing the option 'new install'. If you are worried about losing data - don't. During the install you will get an option 'Which Partitions to Format?'.

If you only choose the root partition where the system is installed and NOT the home partition, all your data and settings including bookmarks, emails etc will still be there.

Yes i chose that option at the beginning of the installation.

Thats pretty interesting.
But what about all the settings i configured in all my tools? Like the default font size of OpenOffice Writer, or my custom display settings, my modified settings in the file explorer and so on?
They'll get lost dont they?

So far after many changes of Mandrake/Mandriva distro I have never lost data or settings (so long as I choose the same softwares - ie if you have Firefox and reload Firefox it will keep your bookmarks).

Also it keeps my Look'n'Feel settings, everything! Just don't ask it to reformat your home partition.

If there is any data that is particularly valuable to you you should be backing that up onto cd's or dvd's anyway.

My hard disk died recently and I thought I had lost everything including thousands of novels in text format I had collected over some years. But I found that most of my stuff was in fact backed-up. Always back-up.

I just tried it in VmWare. It works fine the way you told me.

Everything is the same, the look and feel, the settings in OpenOffice, everything!

I will do it this way. Hopefully that fixes my problem.

Thanks alot.

If you select 'show hidden files' you can see all these in your home directory.
