Storage Manager Architecture (Windows CE 5.0)

Send Feedback

The following illustration shows the storage architecture for the Microsoft® Windows® CE operating system (OS).

When the Storage Manager receives a Plug and Play (PnP) identifier unload notification from a block driver, the notification forces unmounts of the partition driver and of any file systems. During this period, the mount points move into a suspended state and requested I/O access to the mount points fail with ERROR_DEVICE_NOT_AVAILABLE. When the Storage Manager receives a load notification, it examines the block device to see if it is identical to the previously unmounted device. If it is identical, the block device remounts under the previous mount points.
