SYMPTOMS

Consider the following scenario:

You insert a storage device into a Windows Embedded CE 6.0 R3-based device.

Note The storage device is formatted by using the Extended File Allocation Table (exFAT) file system or the Transaction-safe Extended File Allocation Table (TexFAT) file system.
You configure the delay time for the PNPUnloadDelay registry entry in the following path to a specific value:

HKLM\System\StorageManager

Note The delay time is the value of the registry entry.
You suspend and then resume the device.

In this scenario, the Exfat.dll file system driver is unloaded unexpectedly. After the specified time delay, the storage device is mounted with a different volume letter. Additionally, you cannot access the content of the storage device.
