Based on those efforts dezzie I agree it’s something wrong with the USB drive. A dirty/oxidized contact, a bent contact, which may or may not be fixable. If fixable great, if not return the drive, either to where you bought it or to SanDisk would be my suggestion.
I ordered two from Amazon, and they both performaed the same. Skipping thruout. Evewn if it is USB 3.0, it is supposed to be backwards compatible. I have a Lexar 64gb USB 3.0 that works fine.
