Q: How do I enable 48-bit Logical Block Addressing Support for ATAPI Disk Drives in Windows XP?
A: This article describes the Windows XP 48-bit Logical Block Addressing (LBA) support for ATA Packet Interface (ATAPI) disk drives that can enable the capacity of your hard disk to exceed the current 137 gigabyte (GB) limit. This patch will also be included in WindowsXP SP1 which will be available in the future. http://support.microsoft.com/support/kb/articles/Q303/0/13.ASP
