Terry wants to know if SpinRite will work to solve his USB drive issues. Leo says it could, with some limitations on USB drives. But since USB drives are so cheap, Leo doesn't recommend spending the money for SpinRite. It's expensive at $90. You can buy 20 drives for that. Leo throws them out when they fail. And those thumb drives use a cheap form of solid-state memory, and when it fails, it FAILS.
