I had 2 USB3 flash drives (1 Corsair and the other one Lexar) ruined. While plugged into USB2 ports on 2 different desktops, the screen blinked as the cable moved for for the Corsair and when I unplugged the Lexar out. Afterwards, many of the files and folders in the Corsair were corrupted. For the Lexar, none of the 4 computers I tried can read it using USB3 ports. They say format disk even when I plug it in USB3 ports. Any ideas on how I can get to read my Lexar? Thx. John
