I recently upgraded the hard drive in my xbox. When I'm uploading things to it, it seems to stumble on relatively small files around 4k in size. It breezes through the uploading of everything but takes 2-3 seconds to upload these small sizes, meaning that trying to upload something like xbox media center takes eons. Anyone got any ideas why this might be happening? At the same time as changing the xbox hdd, I also went from connecting the xbox to my via a 3com 3c90x pci card to now using my onboard intel pro 100 connection.
