我有一个 Western Digital USB 硬盘驱动器，通常将其连接到 Raspberry Pi。今天我注意到驱动器不再安装，并且在系统日志中没有看到任何解释原因的内容。当我跑去sudo mount /dev/sdc /media/pi/media-2/重新安装它时，我得到：
mount: wrong fs type, bad option, bad superblock on /dev/sdc,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
并sudo fsck /dev/sdc给了
fsck from util-linux 2.29.2
e2fsck 1.43.4 (31-Jan-2017)
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/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>
Found a gpt partition table in /dev/sdc
当我将它连接到运行 Ubuntu 18.04 的笔记本电脑时，它安装得很好并fsck返回：
fsck from util-linux 2.31.1
e2fsck 1.44.1 (24-Mar-2018)
media-2: clean, 1175/122093568 files, 422501325/488369920 blocks
在 pi 上，我尝试将其连接到每个 USB 端口，但没有任何区别。知道为什么它在一台机器上运行而不是在另一台机器上运行吗？
