sudo fsck.ext4 -b 102400000 -B 4096 /dev/sdc1
e2fsck 1.42 (29-Nov-2011)
fsck.ext4: Bad magic number in super-block while trying to open /dev/sdc1
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>
为什么它显示 ext2 文件系统，该死。
这是 mount 命令的输出
sudo mount /dev/sdc1 /media/k
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try

答案1
看起来你正在格式化整个磁盘，而不仅仅是分区：/dev/sdc代表整个驱动器，而/dev/sdc1是其第一个分区。您应该格式化并安装分区，而不是驱动器。
要解决问题，请尝试以下操作：
fdisk使用（或类似 的 GUI ）对其进行重新分区gparted。您应该重新创建 GPT/分区表- 格式化第一的分割 (
/dev/sdc1) 为ext4 - 现在尝试
mount
如果不起作用，请发布以下命令的输出：
fdisk -l /dev/sdc
fsck /dev/sdc1
答案2
为了对其他人有所帮助，我在安装有 Ubuntu 的单板计算机上连接了 2 个（！）磁盘，也遇到了类似的情况。
我无法看到某些文件：
$ ls -l /mnt/somewhere/stuff
ls: reading directory /mnt/somewhere/stuff: Input/output error
我无法再次挂载文件系统：
$ umount /dev/sdb
$ mount /dev/sdb /mnt/somewhere
mount: /dev/sdb: can't read superblock
我无法解决这个问题：
$ fsck /dev/sdb
Attempt to read block from filesystem resulted in short read while trying to open /dev/sdb
Could this be a zero-length partition?
我没有发现任何 SMART 系统错误：
$ smartctl -t short /dev/sdb
$ smartctl -a /dev/sdb
# 1 Short offline Completed without error 00% 6446
最后，这是我们供电的一个硬件错误USB 集线器。不知道能不能在这里说出品牌。
简而言之，不要相信你的 USB 集线器，即使它是最近才出现的问题。告诉你的朋友。这是一个非常严重的问题，会影响使用单板计算机（例如带有 Ubuntu 或其他发行版的 RaspberryPI）的人，而无法使用本机适当的电源。
在这种情况下，我的解决方案是：购买另一个 USB 集线器，并且无论如何购买另一台带有原生电源的单板计算机作为长期计划。
我很好奇这些硬件问题在 Ubuntu 上发生的频率。我无法测试其他操作系统，因此不能 100% 确定这是硬件问题。
