Sandisk II HCSD firmware prob or not ??

Hi

I have just purchased a 8GB Sandisk II HCSD and it wont work on my pc, it keeps throwing out an I/O device error ? . Could this be something to do with my driver/firmware ? As iv tried it on a Dell laptop running Vista with no probs??IM a little unsure on what to do next as iv up dated my drivers with no luck.

Please can anyone help??? :cry:
