General Description
1-4 C141-E219
Error rate increase
1. The drive format at factory shipment is generally 512 bytes.
2. The recoverable Error of the drive might increase when the format would
be modified from 512 bytes to the following values:
516 bytes, 520 bytes, 524 bytes, 528 bytes.
3. The recoverable Error referred here is sense data (1-13-xx).
(13) 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.
(14) High speed positioning
A rotary voice coil motor achieves fast positioning with high performance access control.
(15) Large capacity
A large capacity can be obtained from the HDD 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 SAS primitive or the SCSI command, the host system can start and stop the spindle motor.
(17) Diagnosis
The HDD 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 HDD 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. 2.9 Bels at Ready for the drive. This makes it ideal for office use.
