Each device object has a device type, which is stored in the DeviceType member of its DEVICE_OBJECT structure. The device type represents the type of underlying hardware for the driver.
Every kernel-mode driver that creates a device object must specify an appropriate device type value when calling IoCreateDevice. The IoCreateDevice routine uses the supplied device type to initialize the DeviceType member of the DEVICE_OBJECT structure.
The system defines the following device type values, listed in alphabetical order:
These constants are defined in Ntddk.h and Wdm.h. Check these files to see whether additional device types have been defined.

The FILE_DEVICE_DISK specification covers disk partitions and any object that appears as a disk.

Intermediate drivers usually specify device types that represent the underlying device. For example, the system-supplied fault-tolerant disk driver, ftdisk, creates device objects of type FILE_DEVICE_DISK; it does not define new device types for the mirror sets, stripe sets, and volume sets it manages.
FILE_DEVICE_XXX values in the range of 0 through 32767 are reserved for Microsoft. All driver writers must use these system-defined constants for devices belonging to the system-defined device types.

If a type of hardware does not match any of the defined types, specify a value of either FILE_DEVICE_UNKNOWN, or a value within the range of 32768 through 65535.
