Would it be possible to program a Digispark to erase/reformate a USB flash drive or is this too complicated an operation for such a small device? The reason is so that I can use a flash drive to transfer data to an untrusted machine and then wipe it without putting it in one of my own machines and then reuse it this way ad infinitum.

 

Should be doable.
