I just bought a new backup disk, and I want to check it. It's mounted in
a USB dock.
Running the following gives an error:
root@martha:~# umount /dev/sdb1
root@martha:~# e2fsck -c -c -C 0 -f -F -k -p /dev/sdb1
/dev/sdb1 is in use.
e2fsck: Cannot continue, aborting.
What's causing this and how do I fix it? It's not MATE; I tried
rebooting to rescue mode, but that didn't help.

People sometimes recommend 'fuser' in cases like these in order to
identify processes that might be accessing the drive.
I mean, the message says '/dev/sdb1 is in use.' Perhaps it is indeed.
fuser -v -m /dev/sdb1
Worth a try, maybe, as no one else seems to have suggested it.
