Caviar Green 3 TB drive in Windows XP, recognizes only 800 GB

A great guy that posts here fzabkar sent me a PM with a couple of links that might help I’ll paste it in

I am aware of two ways in which other HDD manufacturers circumvent the 2TiB limit of Windows XP.

Seagate uses DiscWizard, an OEM version of Acronis Disk Director, to emulate two physical drives, 2TB plus   http://www.zdnet.co.uk/reviews/storage-peripherals
