Somewhat later, I was out of town and had an urgent need for a USB drive. In my traveling toolkit, I had a PHICOOL USB drive with an alleged 128GB and USB A, USB C, and Lightning connectors.
Now my SOP is to run ValiDrive on new USB drives. Again, this drive was FAKE only having 32GB of capacity and was ridiculously slow.
Run ValiDrive on EVERY USB drive that you buy, even on memory cards.
