If card has only 1 partition: format in camera.
Otherwise, use same tool you used to multi-partition it to delete patitions, then format with camera or XP
example with aefdisk:
first determine device number of your card:
"aefdisk32 [card-device-no] /show" using 1, 2, etc as card-device-no
once you're sure you got the right device number (look at the size!), do
"aefdisk32 [card-device-no] /delall"
and your card will again be totally blank.
hope that helps,
