[tech] Self-Erasing Flash Drives Destroy Court Evidence … ‘For decades, investigators have worked with tape, floppy drives and hard drives that continue to store huge amounts of information even when the files they’re contained in are marked for deletion. Even wiping the disks isn’t always enough to permanently erase the contents. SSDs, by contrast, store data in blocks or pages of NAND-based transistor chips that must be electronically erased before they can be reused. As a result, most SSDs have firmware that automatically carries out “self healing” or “garbage collection” procedures that can permanently erase or alter files that have been marked for deletion.’
