Nope. It only goes to 2.72 TB, max. I can't remember the name off the top of my head, but the new file system goes much higher now. This is why people can't install 3 TB HDDs as a boot drive, especially with NTSF.
Also, the size of the hard drive allowed depends on the motherboard as well. Add in cards can solve this problem.
Just so others dont think any of this is true, here is the correct info:
The NTFS max volume size is not quite 256 TB.
The Max File size is not quite 16TB. (128GB under XP sp1's version of NTFS)
Max bootable size is 2.19TB under MBR (Master Boot Record) with conventional Bios motherboards
For drives greater than 2TB you can format NTFS using GPT volumes (GUID Partition Table) which are bootable with motherboards using UEFI bios's.
Add in cards will not solve the >3tb boot issue, its strictly a bios function/problem it may work via USB (I've never seen anyone test that)
UEFI is not planned to be compatible with Vista 32, or any version of XP that I am aware of.
