Getting my USB drive mounted in Vista

[irishgrizzly]

I'm trying to transfer files between my mac and a friends laptop. It's a new Dell running Vista SP2. I have the drive formatted to FAT, but I'm not getting any drive in vista. I heard that windows has trouble seeing over 32gigs (or is that working with files that are over 32 gigs?), so I partitioned the drive in half (it's 40gig), still doesn't see it. Any ideas?

thanks

It's a 2.5inch powered by USB. I've attached the extra power cable to my desktop in case it need to draw more power.
