Careful, 'Disklabel' below is a synonym for 'Partition table' (of type 
'dos' in this particular case).

Fortunately `e2label` is smart enough to recognize your drive is 
partitioned and leave it alone[1], otherwise you might be in serious 
trouble now.

What do you actually want to achieve?


[1] as far as I know it's possible to format a drive directly, without 
any partition table, but this is generally not recommended and should be 
avoided.

Kind regards,
Andrei
