For some reason, my USB stick is no longer read on Windows machines. They say it must be formatted. It is formatted as FAT32 and my Mac can read and write to it fine. I seem to recall this happening around when Snow Leopard was released - instead of deleting all the data, I'd usually just re-format it. Is Snow Leopard's partitioning and formatting for FAT32 changed..? This is really irritating as it pretty much renders my USB drive useless. As I said, works fine on my Mac (haven't been able to try any other Macs). What can I do?
