4.3.4.2 Custom SCSI Configurations
The Custom disk configuration mode supports non-standard SCSI configurations.
Custom settings are available under the Disk Configuration/Disk Mode menu.
To properly set up Custom mode, you must specify
• Tracks per disk
• Cluster Size
• Track Grouping
Tracks per D isk: This setting specifies the number of tracks recorded per disk; with
a range from 1 to 24.
Cluster Size: This item selects the desired disk data cluster - either 32 KB or 64
KB. Typically, 64 KB is suitable for most/all hard disk drives, while 32 KB cluster
size is more appropriate for slower devices, such as MO drives. Please consult the
drive manufacturer or Otari Corporation for guidelines.
Track Grouping: The Grouping preference enables you to specify which SCSI
devices are assigned to which tracks.
The Track Grouping configurations use letters (ABCDEF) for each disk drive (up to
six disk drives total) and assigns letters to SCSI ID’s 0,1,2,3,4,5 and 6.

Here is an example of how to set the “Tracks per Disk” and “Track Grouping” for a
setup using six MO drives, each capable of recording on four tracks per disk:
