e2fsck sagt folgendes
Code: Alles auswählen
root@buster:~# e2fsck -v -n /dev/sdb
e2fsck 1.44.5 (15-Dec-2018)
ext2fs_open2: Bad magic number in super-block
e2fsck: Superblock invalid, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/sdb
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>
/dev/sdb contains a iso9660 file system labelled 'WTLIB14X'
root@buster:~# e2fsck -b /dev/sdb
Invalid non-numeric argument to -b ("/dev/sdb")
