I have a new external firewire hard drive set up. It was once an internal IDE hard drive, but I put it in an enclosure to be more portable. The problem is that Windows XP will not recognize it at all. No drive letter, not present in the device manager, nothing. I connected it to my PowerBook and it works flawlessly. I've already reinstalled the Firewire controller on the PC and tried all 3 FW ports to no avail. I've swapped cables twice (though the original cable works perfectly on the PowerBook). I've scanned for new hardware and it finds nothing. Any ideas? It's a FAT32 volume with just 4 gigs of data on it. I tried reformatting it on the Mac, and again, it still works in the PowerBook but does nothing on the PC. It had originally been a Windows file drop drive (FAT32).
