Strange multisession DVD+R behaviour after closing the disc
Hi,
I have written a multisession data DVD+R with Nero Burning ROM 6.3. Then I
haven't added any more session and I have closed the disc with Pinnacle
Instant CD/DVD 8 OEM. The content of this disc is accessible without any
problem under Windows 2000. Under Linux, when I try to mount the disc with
'mount /dev/writer /mnt/writer/', I get this error:
mount: block device /dev/writer is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/writer,
or too many mounted file systems
I (obviously) obtain the same error when i try to use it in my dvd-rom.
The strangest thing is that I can mount (and then access as usual) this disc
with 'mount -oloop /dev/writer /mnt/writer'
Have you got any idea about this behaviour? Is it possible to make the disc
'normally' (without '-oloop') mountable again?
Thanks in advance,
Mirco Lorenzoni
