Flash memory is problematic for secure data. Basically, its nearly
impossible to securely erase a file from flash based disks.
I don't know how that can be true. I can understand deleting doesn't work
but is it true a simple dd if=/dev/zero of=/dev/sdx onto the flash card
doesn't fill it with zeros? And even if it doesn't, how hard is a flash
card to destroy? Hard disks are tough as nails but flash memory can be
snapped in two with your hands or a pair of pliers and burned...
AFAIK, the "accepted" method involves a thermite grenade. :)

Political correctness is a doctrine, fostered by a delusional, illogical
minority, and rabidly promoted by an unscrupulous mainstream media, which
holds forth the proposition that it is entirely possible to pick up a turd
by the clean end.
