Public bug reported:
Hi,
Today I try to mount an UDF CD-ROM make with Windows on Ubuntu, I get an error.
I try with Debian Lenny, and the CD-ROM can be mounted, so it's not my CD-ROM
that it's bad.
I made an image with Debian and k3b, see attachment. You can mount this
file on Debian Lenny with this command : mount -oloop,ro -tudf,iso9660,
crapscd.img /tmp/foo
This is the output of dmesg when mounting on Debian Lenny :
[396711.873751] UDF-fs: Filesystem marked read-only because writing to
pseudooverwrite partition is not implemented.
[396711.873809] UDF-fs INFO UDF: Mounting volume 'UDF Volume', timestamp
2009/08/24 17:39 (1078)
Now I try to mount on Ubuntu Hardy :
[ 4270.885661] UDF-fs: No fileset found
[ 4270.886529] ISOFS: Unable to identify CD-ROM format.
I can mount this image with Ubuntu Jaunty, but the original CD-ROM can't be
mounted on Ubuntu Jaunty (dmesg output) :
(mounting image)
$mount -oloop,ro -tudf,iso9660, crapscd.img /tmp/foo

And it's the same CD-Drive that read perfectly this CD-ROM under Debian Lenny
or Mircrosoft Windows XP, so it's not my drive that it's bad but something with
the Ubuntu kernel or something else.
