Formatting a SCSI disk

About formatting a SCSI disk:

You will format a SCSI disk in the “Disk Format?” menu in Setup mode.

During formatting, the D-160 automatically checks the performance of the connected SCSI device, selects and displays an appropriate format type from TYPE 0 - TYPE 2 (TYPE 2 is selected as a default setting). The user can manually select the desired type.

<Notes on real time recording and playback>

Logically, you can perform real time recording/playback if your case is described under the <Possible> category in the table shown on the above. However, the sound might skip, depending on the condition of the connected SCSI drive disk.

The D-160 performs experimental reading and writing at two points on the disk to measure the performance of the connected SCSI device, and based on the results, such as the response time of the disk, it will determine the format type (TYPE 0-2). Therefore, for parts of the disk other than the two measured points, you do not know if the disk will maintain adequate speed to realize real time recording/playback.

It might be possible that the sound skips during real time recording or playback within the untested parts. Measuring two points for performance can indicate tell whether or not the disk is reliable, but this is only an “index.” Fostex will not guarantee the operation of the SCSI disk.
