This article describes a hotfix rollup that improves Windows Vista and Windows Server 2008 compatibility with Advanced Format disks. Advanced Format disks have a 4-KB physical sector size. This hotfix is only for Advanced Format disks that have a 4-KB physical sector size and that emulate a 512-byte interface for logical addressing.
Note: Advanced Format disks introduce a larger physical sector of 4 KB. However, these disks have a 512-byte interface for logical addressing to make initial versions more compatible with current computer systems. Therefore, these disks are known as “512-byte emulation disks” or as “512e.”
