While I don't have any idea how harddisks work internaly thise days,
I've no problem to loose 4k or even 16k if it improves anything.
But I would still like to get it to the beginning of the
partition/drive/device.
Mainly to be able to do
less -f $DEVICE
to figure out what it's all about. I do this more often than not and
hate it if all i get back is just binary garbage.
Everyfile should tell me what is is for/from in plain text.
