my cruzer doesn't work

As far as I can tell…there has been no damage to my cruzer and I have only had it for about 1 year.  I plug it in, USP port and although the light flickers in it both the desk top (Windows) that I work on and my personal computer (Mac) do not provide an icon or recognize its presence. I have tried to take it back to Radio Shack and they cannot exchange it as there is no record because I purchased it in cash.

What’s wrong with my Cruzer, migro 2.0GB, U3 smart?

Any suggestions will be greatly appreciated

Same here. It work’s on Dells for me, but nothing on Mac.
