Watch out for external USB2 drives. If you create a 3GB or larger file, you may not be able to transfer it via USB2. I had a 3.9GB video file and could not transfer it over to my PC. This being an IDE drive, I yanked the drive out of the enclosure, hooked it up via regular IDE, and when XP started, it checked the drive for errors. No errors were found and I could then copy the file from the formerly USB2.0 drive now IDE just fine.
