[mdlug] Unable to mount a dvd on a drive which was used to write it.

[R KANNAN]

Hi

I am having problem mounting a dvd created by the same drive. It never
gets mounted using the drive on which it was burnt.

The fstab entry for the drive says

/dev/sr1     /media/bd   auto       ro,noauto,user,exec   0 0

After I run the mount comand, I cannot see the contents of the drive
under /media/dvd

But the /etc/mtab entry for the drive says..

[/dev/sr0 /media/dvd iso9660 ro,nosuid,nodev,user=kannan 0 0

though k3b seems to recognize the drive and seems to burn fine.

dmesg gives the following

I can mount the dvd fine using another drive on the same box.

Any ideas.

TIA for any help.
