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...
We may be using flash both for external storage
and internal storage.
Flash memory is problematic for secure data. Basically, its nearly
impossible to securely erase a file from flash based disks.
