Ciao a tutti, volevo chiedervi una mano: da quando ho installato Ubuntu 9.10 ho alcuni problemi con il lettore DVD [un DVD-RW LG, interfaccia IDE]: ogni volta che inserisco un DVD mi viene restituito questo errore:
mount: tipo fs errato, opzione non valida, superblocco su /dev/sr0 danneggiato,
codepage o programma ausiliario mancante, o altro errore
In alcuni casi si possono trovare informazioni utili in syslog. Provare
ad esempio 'dmesg | tail'.
Ecco il mio /etc/fstab:
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# / was on /dev/sda1 during installation
UUID=b18777cc-525a-4841-a113-78bf92ee0d4c / ext4 errors=remount-ro 0 1
# /media/backup/ was on /dev/sda4 during installation
UUID=DC8A7F978A7F6D40 /media/backup/ ntfs defaults,nls=utf8,umask=007,gid=46 0 0
# swap was on /dev/sda5 during installation

/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
/dev/scd1 /media/cdrom1 udf,iso9660 user,noauto,exec,utf8 0 0
Seguendo il consiglio e digitando dmesg | tail ottengo questo output:
[ 2999.455008] sr 8:0:0:0: [sr0] Add. Sense: Illegal mode for this track
[ 2999.455024] end_request: I/O error, dev sr0, sector 135436

Non capisco... ho fatto alcune prove, cambiando in fstab /dev/scd0 con /dev/sr0, o mettendo il simbolo commento davanti alla stringa per ignorarla [ho visto il mio problema anche in molti altri utenti Linux] ma non cambia nulla, potete aiutarmi?
