By the way, does somebody knows about the flash memory?
Is zeroing a whole usb key enough to make the data unrecoverable?
No, wear-leveling (done at the memory controller level) will dynamically
re-map addresses on the actual flash chip to ensure a relatively
consistent number of write cycles across the entire drive.
The only way to completely "wipe" a flash disk is with a hammer.
