i have developed this procedure for mounting DVD-R that has multisession on it on older dvd-readers (or other that would not mount it)
situation:
-you have older dvd reader , for.ex on laptop
or on desktop computer
-presumably it is still functional (they built it well those days)
-you burn multissesion in two or three or 4 sessions
and when you insert it in laptop it only show first session
there is workaround! (on linux operating system only)
for UDF mutilsession DVD
=========================
Code: Select all
mount /dev/hdd /mnt/cdrom2 -s -t udf -o ro,user,noauto,exec,umask=0,session=0,lastblock=2135200
Code: Select all
dvd+rw-mediainfo /dev/hdd
it is about at the bottom of listing
for ISO multisession (in case of old device) DVD¨¨¨¨¨¨¨¨

===========================================
Code: Select all
# umount /dev/hdc
# mount /dev/hdc /mnt/cdrom2 -s -t iso9660 -o ro,user,sbsector=2111936
# umount /dev/hdc
# mount /dev/hdc /mnt/cdrom2 -s -t iso9660 -o ro,user,sbsector=2111936,unhide

cdrecord dev=0,1,0 -media-info
(but this is obsolite , is it scsi emulation ?
Code: Select all
sudo mount -t iso9660 -o ro,user,noauto,umask=0,sbsector=146042 /dev/scd0 /mnt/cdrom
this way is going to mount previous session , without last ?Disk type: DVD, HD-DVD or BD
