// Description:

// e32test\defrag\t_defrag_ref.cpp

// Overview:

// Test application that uses the reference defragmantation driver to invoke

// the top-level defragmentation operations.

// API Information:

// RBusLogicalChannel

// Details:

// - Load and open the logical device driver ("D_DEFRAG_REF.LDD"). Verify

// results.

// - Request that the driver attempt to trigger various defragmentation

// operations. Verify that they complete successfully.

// Platforms/Drives/Compatibility:

// Hardware only. No defrag support on emulator.

// Assumptions/Requirement/Pre-requisites:

// Failures and causes:

// Base Port information:

//
