Optical drive problem Mandriva 2008.0


Hi,

I have a problem with the cd/dvd drive on my recently installed Mandriva 2008.0

If I try to write data to it I get this message - "Could not start process Unable to create io-slave: klauncher said: Unknown protocol ''."

First noticed it when I was trying to do a backup through Mandriva control centre - the backup fails with: - "Error: Does not appear to be recordable media!"

Drive shows up in Konquerer and will read data OK, but not write. Works OK with other distros and livecds etc

Any ideas?

Thanks

Matthew

My first guess would be a permission problem. If you are trying (as user) to write to a directory forbidden to you, you will get write permission errors.

OK - thanks for the quick response.

How can I check that/change it?

First, I'm assuming the cd/dvd drive is cd-rw and dvd-rw capable (can read and write cd/dvd).

Second, you need to check your /etc/fstab for the cd/dvd writer mount parameters. It should look something like
Code:
/dev/dvdrecorder     /media/dvdrecorder   subfs      noauto,fs=cdfss,rw,procuid,nosuid,nodev,exec
Note the rw in the mount parameters. It yours reads ro, then it's mounted 'read only' and won't write.

There's also that issue of 'Does not appear to be recordable media'. The disk you are trying to write may be bad. Have you tried others?

OK

This from /etc/fstab:- /dev/cdrom /media/sr0 auto umask=0,user,iocharset=utf8,noauto,user_xattr,rw 0 0

I have tried several disks - and there is no problem wif I use a live cd like puppy etc.

Any other ideas?

Thanks

Hi all - just bumping myself up to the top again

Anyone any other ideas why this drive is not able to record?

It recognises that there is a blank media present, but will not record - however many different discs I try

Thanks....

I had some problems with my cd/dvd writer in the past in Mandriva, it was not detected correctly by the system, but after a simple reboot it worked by itself. I think the drive was not correctly detected from the beginning. You could also try to burn a cd with some other software, maybe it will work.
