Okay, I once had a My Books Essentials 3TB USB2.0 external drive that worked fine with Windows XP 32 bit. The drive went foul after a few years.
I bought a My Passbook 2TB USB drive (observing the 2TB limit) and I cannot assign a drive letter but it does show up in Disk Management as Healthy GPT.
What do I need to do to get this drive to work with XP?
