Hopefully someone else has had this problem, I haven't been able to find any posts about it. i have a 24" iMac, 2.33 Core2Duo runninng 10.5.4 and Windows xp (sp3) under boot camp. I also access the boot camp partition via Fusion, but haven't had any issues there so far. My problem is that I have 2 external drives connected to my computer. One firewire 400, one usb2. If I have either (or both) of them connected to my computer when starting up in windows, windows won't start. It just hangs on the Windows XP screen (black background with progress bar at the bottom) until I reboot the machine with the drives unplugged. Both drives are formatted HFS+ and in Windows I have software that allows these drives to be accessed. (Not Macdrive, but something just like that). No matter what I've tried, Windows just won't start if an external drive is connected. I've asked a handful of people who know Windows really well, and everyone is stumped. Has anyone else had this problem? Or even if not, anyone have any ideas how to fix it? It's really a pain to keep having to unplug these drives every time I boot into Windows via boot camp. thanks for any help!
