Well I never - it certainly *does* erase data from a floppy disc.  I
didn't know that - it seems the disc gets filled with F6s (1111 0110),
aside from the bits which are filled with 0s and the other bits that
hold useful information about the disc.  I still don't know about HDDs,
though (I've just tried erasing a floppy and looking at it with a disc
editor; I'm not so keen on trying the same game with a HD volume).

Indeed; hence the use of Burn and its friends for to over-write a file
if you're worried about people recovering data you've deleted.
