+// 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:
+// 
+//
