I just got an firewire 800 external hard drive enclosure and put a 250 hard drive in it. I formated it with partition magic to fat 32 so that I get one big 150 Gb drive that's able to be read by my powerbook and the windows xp machine. I'm just wondering if I can connect the drive to the 2 computers at the same time?? Whenever I plug the drive to my powerbook first, then plug anohter cable to the firewire port on the drive to the windows xp machine, the windows xp will say that it found an unknown device and want a drive for that, and it can't read the drive. Only when the drive is connected to either of the computer ONLY, the computer will be able to read it and write it... so do you guys know if there's a way to fix this? Thanks
