[Usb] input i/o error

[meki]

durante una copia mal riuscita ho dovuto forzatamente staccare il disco usb esterno alla linuxbox
da allora non riesco + a montarlo, ne a vederlo con gparted.  :-\

i mnessaggi in console con dmesg sono i seguenti

che dite? danno fisico e butto via tutto?
ci sono speranze?
se do  sudo /sbin/fdisk -l /dev/sdb
talvolta compare quxlhe info. altre rimane appeso. grazie!



ps: almeno con linux continuo a lavorare. win appena ci caccio il disco crasha explorer.exe!!! (rotfl)

Attacca il disco e lancia "sudo fsck /dev/sdb".

mauro@afrika:~$ sudo fsck /dev/sdb
[sudo] password for mauro: 
fsck 1.40.8 (13-Mar-2008)
e2fsck 1.40.8 (13-Mar-2008)
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sdb

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>

e2fsck -b 8193 /dev/sdb ? (yes) chiedo prima di far danno ... intanto ti ringrazio
la partizione è ntfs creata da gparted precedentemente

non ho resistito a non provarci ...

situazione disperata? ???
