Storage

A simple cross-platform tool for flashing OS images to SD cards and USB drives with validation built in.

Steve Gibson's legendary hard-drive maintenance and data recovery utility from GRC. Boots from its own media and works down at the magnetic surface to test, refresh, and often recover sectors that the OS has given up on — the kind of tool you hope you never need until you really, really do.

Quickly spot-check any USB mass storage drive for fraudulent deliberately missing storage. Fraudulent USB/SD storage being sold through trusted marketplaces has exploded and using/trusting a bad drive can have immediate horrible consequences. Use this utility to CYA!
