 // 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:

 //
