I have an 3TB external disk and Windows XP 32 bit. It works as a USB 2 disk with its enclosure, but I want to use it as an internal SATA disk. I don't want to use it as a boot disk, only as a data disk. I understand that normally I need GPT (GUID partition table), and then I can't use Windows XP 32 bit anymore. I would prefer to avoid this. But what I did not understand by googling around is: can I partition the disk in 2 parts (so that each part is less than 2TB) with MBR and use it in Windows 32-bit? If yes, which tools do I need?

I've retagged this as the OS is important for the question. –  ChrisF Nov 9 '11 at 20:02

You could use Paragon GPT Loader ($19.95) which :

  • Allows the use of all disk space on a 2.2TB+ drive under Windows XP
  • Augments Windows XP by adding support for GPT disks

Or you could use the free GIGABYTE 3TB+ Unlock Utility to create two virtual drives on the disk : 2TB + 1TB, if your motherboard is on the supported list.

Or you could upgrade to a modern operating system to go with your modern hardware. :) Good solutions, though - I've never used that particular app, but Paragon is legit. –  Shinrai Nov 9 '11 at 20:57
    
Would pre-partitioning it into smaller partitions work? –  Moab Nov 9 '11 at 22:13

@Moab: Not without GPT. –  harrymc Nov 9 '11 at 22:18
    
@harrymc: "Not without GPT" is the answer to my question, so I accept it. So I will get Windows 7 64 bit. –  carlo.borreo Nov 9 '11 at 23:00
    
That is the best way to go. –  harrymc Nov 10 '11 at 6:19
