Set CMOS hard drive setup to Auto-Detect with LBA mode enabled. 

New INT13 Extensions and LBA mode in BIOS and FAT32 or NTFS-based 
file systems are required to acheive full capacity. FAT32 file 
system can create single partitions and logical drives up to 2TB.

========================

Windows XP Service Pack 1 and Windows 2000 Service Pack 3 with 
48-bit LBA Address drivers are required for native support of
ATA (IDE) disc drives greater than 137GB.

Windows 98, Windows Millennium and Windows NT 4.x all have 137GB 
native limitations supporting ATA (IDE) disc drives. Third-party
device drivers may be available from motherboard or host adapter
manufacturers for these legacy Windows operating systems.

Already low-level formatted at the factory.
