FIX: A USB storage device that does not contain the MBR and is formatted as NTFS cannot be mounted on a Windows Embedded Compact 7-based device

Symptoms

Consider the following scenario:

  • You have a Windows Embedded Compact 7-based device that is installed with a customized file system driver for the New Technology File System (NTFS).

  • You have a USB storage device that does not contain the master boot record (MBR). Additionally, the USB storage device is formatted as NTFS.

  • You start the device and attach the USB storage device.


In this scenario, you find that the system cannot mount the USB storage device and recognizes it as unformatted.
