USB equivalent of degaussing

Hi,

Buy a large steel magnet and use it to smash the stick into really small pieces 😉

If a hard drive is degaussed, then the chance of recovering data is near enough to impossible.

Does anybody know what the equivalent to degaussing is on USB sticks? A technique which can be used to delete data on USB sticks that can almost certainly near be recovered?
Because USB's are electrical, as opposed to magnetic.

Thanks

Some form of BFH technology would be best.

When I search for BFH technology I get results about hip replacement.
What does it stand for?

Thanks

Maybe something about a hammer????
Think BFG from DOOM…… wink

I think BFH is probably Big $%^#ing Hammer in this case )

I was going for the slightly more subtle approach………. wink

Mechanical destruction of the electronics in the USB stick.

What is wrong with just overwritting every sector. The only slight proviso is if there are old sectors that have been reallocated with a wear leveling routine on the chip.

If the chip has apparently died, then yes a sledge hammer

With a chip it is not possible to read it slightly off track so data is lost when overwritten - or is there something I am missing?

In reality, with wear levelling, could you honestly stand up and say "this drive is wiped?" with conviction? The truth is, you do not know. How can you know?

You don't have access to the sectors which have been re-mapped. Obviously, neither does anyone else for that matter. The only way to access the remapped area's, is by writing enough data to the drive, enough times such that they come into play again, at which point they are overwritten, leaving the question, is this a remapped sector? It really is a case of "don't know".

I dare say a piece of software could be created which wipes so many times that re-mapped blocks "must" be overwritten, would you trust it though?

Use a hammer. It's conclusive, less time consuming and much more fun/satisfying…
