I have a Western Digital USB hard drive which I typically leave connected to a Raspberry Pi. Today I noticed that the drive wasn't mounted anymore, and didn't see anything in the syslog to explain why. When I ran sudo mount /dev/sdc /media/pi/media-2/ to re-mount it, I got:
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.
And sudo fsck /dev/sdc gave
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
When I connect it to my laptop running Ubuntu 18.04, it mounts just fine and fsck returns:
fsck from util-linux 2.31.1
e2fsck 1.44.1 (24-Mar-2018)
media-2: clean, 1175/122093568 files, 422501325/488369920 blocks
On the pi, I tried connecting it to each of the USB ports and it didn't make any difference. Any idea why it works on one machine and not another?
