1. This post belongs in the xp forum.
2. Yes I have seen this before… xp and modern terabit drives are incompatible.
3. Imo the xp system is reading that as a 2 TB Raid 1 (Mirrored) drive in the MBR format… it could also be a hybrid drive with a ssd wafer but that is much less likely:
a. What is the make, model and brand of the drive?
b. Is it internal, nat or usb?
c. Motherboard bios settings?
If the motherboard can't support the drive internally then ime a nat setup is your best chance but honestly I'd recommend moving up to a w7 or even w8 system and just making the xp a virtual | dual boot… it's your system.
