(14)Defective block slipping
A logical data block can be reallocated in a physical sequence by slipping the defective data block at formatting. This results in high speed contiguous data block processing without a revolution delay due to defective data block.
(15)High speed positioning
A rotary voice coil motor achieves fast positioning with high performance access control.
(16)Large capacity
A large capacity can be obtained from the HDDs 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.
(17)Start/Stop of spindle motor
Using the SCSI command, the host system can start and stop the spindle motor.
(18)Diagnosis
The HDD has a diagnostic capability which checks internal controller functions and HDD operations. Also, for early detection of and recovery from the errors on the disk, the HDD has a function for periodically implementing a full scan of the disk.
(19)Low power consumption
By using highly integrated LSI components, the power consumption of the HDD is very low, and this enables the unit to be used in wide range of environmental conditions.
(20)Low acoustic noise
The acoustic noise level is low; approx. 3.6 Bels at Idle. This makes it ideal for office use.
(21)Microcode downloading
The HDD implements the microcode download feature. This feature achieves easy maintainability of the HDD and function enhancing.
