Executing the Defrag Procedure on an AW2816 Hard Drive
After frequent recording and editing, audio data saved or recorded to the AW2816's internal hard disk will gradually become scattered or ''fragmented'' across multiple locations on the disk. The result can be slower access speeds as the AW2816 must search through different parts of the fragmented disk for the audio data that belongs to a particular audio file. If this becomes severe, the access speed during playback may be slowed enough to cause ''skips'' in the sound, or it may be impossible to create a new song even when there appears to be sufficient free space.
The Defrag function solves the problem of fragmentation. When Defrag is executed, the audio data on the internal hard disk will be transferred to a vacant area, and will be rearranged so that the data for each song is located in a continuous area on the disk.

NOTE: The Defrag operation normally requires approximately one hour per GB of disk space, depending on the arrangement of data on the hard disk and on the song structure. In some cases, processing may end before the displayed time.
WARNING 1: It is possible that while Defrag is being executed, a read/write error will occur on the hard disk, damaging the audio data without the possibility of recovery. To avoid the potential loss of important Song data, it is recommended that the data residing on the hard disk be saved to another location before performing this procedure.
WARNING 2: The AW2816 should never be turned off while Defrag is in progress. If the power is turned off while the Defrag operation is being performed, the internal hard disk and/or the data may be damaged severely and irrecoverably. Before beginning this procedure, make sure that the power cable is secured and there is no chance that it will be accidentally unplugged from the outlet. Also, do not perform this operation if there is any possibility of power failure due to lightning or power line irregularities.
