Pentax WG-3 Quick Manual page 10

• When using an SD Memory Card with a slow recording speed,
recording may stop while recording a movie even if there is adequate
space in the memory, or image capture or playback may take a long
time.
• Please note that deleting data, or formatting the SD Memory Cards or
the built-in memory does not completely erase the original data.
Deleted files can sometimes be recovered using commercially
available software. It is user's responsibility to ensure the privacy of
such data.
