在 Dell Insperion N4110 Corei3 上新安装了 22.04.2。当我从 live CD 运行 fsck 时，我得到：
ubuntu@lubuntu:~$ sudo fsck -f /dev/sdb
fsck from util-linux 2.37.2
e2fsck 1.46.5 (30-Dec-2021)
ext2fs_open2: Bad magic number in super-block
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 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>
Found a dos partition table in /dev/sdb
lubuntu@lubuntu:~$
Dos 分区可以去掉。我不需要它。建议的超级块也不起作用。
