Applications that are built on ESENT and that run on a Windows Vista-based or Windows Server 2008-based computer may not work correctly after the reported physical sector size of the storage device changes

Storage devices have traditionally been based on 512-byte sectors. Recently, storage device vendors have begun to transition to storage devices with a sector size of 4,096 bytes (4 KB). These are known as “Advanced Format Disk” or “512e” devices. Although support for these storage devices that have various software and hardware components of a system is improving, support may remain inconsistent. The most common inconsistency is that support for accurate reporting of the physical sector size of these storage devices is inconsistent. Therefore, applications must handle scenarios where the reported physical sector size of the storage device they are operating on may change.
