Well, in that case, I'd write the fsck script in such a way, that either
aborts if the filesystem is mounted or that it waits until filesystem
got unmounted.

# Check out /dev/disk/by-id for this
jump_drive_id="ata-WDC_WD1002FAEX-00Y9A0_WD-WCAW32263803"
jump_drive_id_dev="/dev/disk/by-id/$jump_drive_id"

while mount | grep $( readlink -f "$jump_drive_id_dev" ); do
  # jump drive is still mounted
  # wait a bit
  sleep 42
  # or abort
  # exit 1
done
# jump drive is not mounted
fsck "$jump_drive_id_dev"
# Done
exit $?
# EOF


Or something like that…
