Is there a secret incantation for destroying an EFI
partition on a USB memstick? After installing FreeBSD,
I would like to re-use a memstick, but
% gpart destroy da0
gpart: geom 'da0': Read-only file system
% gpart destroy -F da0
gpart: geom 'da0': Read-only file system
% gpart show da0
=> 40 60063664 da0 GPT (29G)
40 60063664 1 ms-basic-data (29G)
% gpart delete -i 1 da0
gpart: geom 'da0': Read-only file system
% dd if=/dev/zero of=/dev/da0 bs=1m
dd: /dev/da0: Read-only file system
