Am un ssd care a crapat, mai are partitia si datele dar nu pot sa le accesez.
Am incercat diverse metode, dar n-am reusit.
Cum pot sa o corectez? Nu vrea sa rescrie superblock.

Pai da, dar...

e2fsck: Invalid argument while trying to open /dev/sdc
/dev/sdc:
The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
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>
or
e2fsck -b 32768 <device>

nu stiu care sunt superblock-urile de backup
Cele 2 de mai sus nu sunt bune
