Well spotted! - Its just for storage as my system drive only has a few hundred gig left. I'm dual booting 64-bit versions of Win7 and Fedora 14. I know win 7 should be able to read and write, just not boot. If fedora can't then I'm sure it will get patched soon enough.
The drive you linked to looks good to me! - Excellent dabs and lambda-tek sell it in the UK!
Edit: Oops, no they don't! Listed on lots of sites but all of them have no stock!
