    1.18 +// Overview:
    1.19 +// Test application that uses the reference defragmantation driver to invoke
    1.20 +// the top-level defragmentation operations.
    1.21 +// API Information:
    1.22 +// RBusLogicalChannel
    1.23 +// Details:
    1.24 +// - Load and open the logical device driver ("D_DEFRAG_REF.LDD"). Verify
    1.25 +// results.
    1.26 +// - Request that the driver attempt to trigger various defragmentation
    1.27 +// operations. Verify that they complete successfully.
    1.28 +// Platforms/Drives/Compatibility:
    1.29 +// Hardware only. No defrag support on emulator.
    1.30 +// Assumptions/Requirement/Pre-requisites:
    1.31 +// Failures and causes:
