Flash Drive isn't recognized on mac

[elit3nemesis]

I have a 4GB Sandisk U3 Titanium flash drive and it is not being recognized under disk utilities, but when I go under about this mac>more info> i see that it is under USB. I used to use it on a PC laptop. What must I do to restore it if not just able to run it on this macbook pro? Thanks.

Looks like mixed results. Certain features don't work.
