I just built a comp tonight and installed WinXP Pro (no SP1 or SP2) so the install only recognized 128GB of my 400GB Seagate SATA drive. After setting up the OS and installing a myriad of updates including SP1 and SP2 windows is still not recognizing the drive as 400GB. what do i need to do? I thought post installation of the SP's the drive would be fully recognized.
