[Mount] abilitazioni dischi fissi

[vincenzo_piccinno]

ho un disco fisso con due partizioni sdb1 ed sdb5, mi capita  che il sistema mi impedisca di salvarci file in quanto li riconosce come proprietà dell'utente root.
per maggiore dettaglio posto un po di comandi:
vincenzo@vincenzo-desktop:~$ sudo nano /etc/fstab

se do i comandi umount e mount succede questo:

vincenzo@vincenzo-desktop:~$ sudo umount -a
umount: /var/run: device is busy.
        (In some cases useful info about processes that use
        the device is found by lsof(8) or fuser(1))
umount: /dev/shm: device is busy.
        (In some cases useful info about processes that use
        the device is found by lsof(8) or fuser(1))
umount: /dev: device is busy.
        (In some cases useful info about processes that use
        the device is found by lsof(8) or fuser(1))
umount: /: device is busy.
        (In some cases useful info about processes that use
        the device is found by lsof(8) or fuser(1))
vincenzo@vincenzo-desktop:~$ sudo mount -a
vincenzo@vincenzo-desktop:~$ ^C
vincenzo@vincenzo-desktop:~$

[steblar]

beh intanto
umount -a tenta di "espellere" tutte le partizioni montate, e tipo /var/run sono in uso quindi non te lo permette. Per i file hai controllato se i permessi sono giusti ?

[vincenzo_piccinno]

i permessi di tutte le cartelle ed i file contenuti sono gli stessi:
solo root può creare e modificare i file in quanto proprieterio delle cartelle A1 ed A5. Le condizioni si applicano a tutto quello che c'è sotto.
Siccome non sono stato io a creare queste condizioni, e sono l'unico in casa che amministra il sistema, può essere che abbia subito un attacco esterno?

[steblar]

controlla che le partizioni non vadano su in read-only

[vincenzo_piccinno]

ho appena finito di installare il nuovo sistema 11.10 e non riesco ad accedere alla partizione del disco dati.
ho un disco dati da 200 Gb diviso in due partizioni, una riesco a montarla, l'altra no e purtroppo ci sono lì tutti i dati.
il disco sembra in buono stato.
