General Description

(12)Error recovery

The HDD can try to recover from errors in Fibre Channel Loop or the disk drive using its powerful retry processing. If a recoverable data check occurs, error-free data can be transferred to the initiator after being corrected in the data buffer. The initiator software is released from the complicated error recover processing by these error recovery functions of the HDD.

(13)Automatic alternate block reassignment

If a defective data block is detected during read or write the HDD can automatically reassign its alternate data block.

(14)Programmable data block length

Data can be accessed in fixed-block length units. The data block length is programmable, and can be specified at initializing with a multiple of four within the range of 512 to 528 bytes.

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).

(15)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.

(16)High speed positioning

A rotary voice coil motor achieves fast positioning with high performance access control.

(17)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.

(18)Start/Stop of spindle motor

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