Defragmenting A Disk; Copying Data In The Disk - Akai DPS12 Operator's Manual

Defragmenting a disk

Repeated recording and edit operations on the DPS12 fragments audio data written on the disk. If this fragmenta-
tion is significant, recording or playback may be interrupted. The DPS12 enables you to re-align the fragmented
audio data ("defragment") to solve this problem. Follow the steps below to defragment a disk.
You can check the busy meter in the MAIN screen to see how frequently a disk is accessed. If the meter
TIP :
often appears as shown below, defragment the disk as soon as possible.
NOTE : When you record and edit on the DPS12 repeatedly, an alarm message may appear, indicating that
there is not enough space on the disk, in actuality the hard disk has enough space available. This means that
the internal audio management table (an area where audio data is managed) on the DPS12 does not have
enough memory space. In this case, you can defragment the disk to reduce the used space in the audio
management table and regain available space on the disk.
1. While the DISK SETUP screen is displayed, move the cursor to the SCSI ID of the drive you wish to
defragment.

• When the alignment operation is performed, the UNDO data will be lost.
