Store and Go Verbatim memory stick - computer sees disk but not contents...

Have a 32 GB verbatim memory stick - the computer will recognise that a USB stick is there but does not show the contents. I've tried it on other computers/different USB ports- same result. Any suggestions??

There are lots of fake sticks out there (especially on eBay), so make sure the stick is good by testing it with H2testw, which I've been using for many years to test every flash card/drive/stick that I buy:

Here's what its output looks like when the drive is clean:

Test finished without errors.
You can now delete the test files *.h2w or verify them again.

H2testw is often referred to as the Gold Standard for finding fake flash drives. Regards, Joe

If you look at it with fdisk (DOS) does it show a recognizable partition?
