Instead of '/dev/sdb1' you should use the 'UUID' or a 'lable' to refer
to that partition.

In the case of your brother, I would do:

$ blkid -s UUID -o export /dev/sdb1

 From the output of the above cmd, substitute '/dev/sdb1' by the all
UUID line.


You also might consider changing your mountpoint from using '/'..


To answer your other question:

'# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
