What about wipefs?
"wipefs allows to erase filesystem or raid signatures (magic strings)
from the device to make the filesystem invisible for libblkid. wipefs
does not erase the whole filesystem or any other data from the device.
When used without options -a or -o, it lists all visible filesystems and
offsets of their signatures."
