General Description
1-4 C141-E237
(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 SAS primitive or the SCSI command, the host system can start and stop the spindle motor.
(18) Diagnosis
The HDDs have a diagnostic capability which checks internal controller functions and drive
operations to facilitate testing and repair.
(19) Low power consumption
By using highly integrated LSI components, the power consumption of the HDDs is very low, and
this enables the units to be used in wide range of environmental conditions.
(20) Low noise and low vibration
The noise level is low; approx. 3.5 Bels at Ready for the drive. This makes it ideal for office use.
(21) Microcode downloading
The HDDs implement the microcode download feature. This feature easily achieves maintenance
and function enhancement of the HDDs.
