    15 // Overview:
       
    16 // Test application that uses the reference defragmantation driver to invoke
       
    17 // the top-level defragmentation operations.
       
    18 // API Information:
       
    19 // RBusLogicalChannel
       
    20 // Details:
       
    21 // - Load and open the logical device driver ("D_DEFRAG_REF.LDD"). Verify
       
    22 // results.
       
    23 // - Request that the driver attempt to trigger various defragmentation
       
    24 // operations. Verify that they complete successfully.
       
    25 // Platforms/Drives/Compatibility:
       
    26 // Hardware only. No defrag support on emulator.
       
    27 // Assumptions/Requirement/Pre-requisites:
       
    28 // Failures and causes:
