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??

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

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:
http://www.softpedia.com/get/System/System-Miscellaneous/H2testw.shtml

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.
Writing speed: 40.1 MByte/s
Reading speed: 76.6 MByte/s
H2testw v1.4

Here's its output when it finds a problem (this was a 4GB card with some bad memory):

The media is likely to be defective.
3.8 GByte OK (8093404 sectors)
146 KByte DATA LOST (292 sectors)

Here's an example of another bad one (this was a fake 32GB card):

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