(15)Large capacity

A large capacity can be obtained from 3.5 type disk drives by dividing all cylinders into several partitions and changing the recording density on each partition (constant density recording). The disk subsystem with large capacity can be constructed in the good space efficiency.

(16)Start/Stop of spindle motor

Using the SCSI command, the host system can start and stop the spindle motor.

(17)Diagnosis

The IDD has a diagnostic capability which checks internal controller functions and drive operations to facilitate testing and repair.

(18)Low power consumption

By using highly integrated LSI components, the power consumption of the IDD is very low, and this enables the unit to be used in wide range of environmental conditions.

(19)Low noise and low vibration

The noise level is low; approx. 3.5 Bels Ready for the drive. This makes it ideal for office use.

(20)Microcode downloading

The IDD implements the microcode download feature. This feature achieves easy maintainability of the IDD and function enhancing.
