Oh yeh. Thing is, I think its the drivers that get screwed up. When I plug my mac in, XP shows many different drivers/devices for the one mac book. For example, under control panel's device manager the mac book pro shows up as an actual disk drive, as a general storage device, and as generic firewire device. And one of these devices (it varies) will show an error stating that "the device is already installed".
I'm lost on this one.
