(10)Error recovery

The IDD can try to recover from errors in SCSI bus 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 IDD.

(11)Automatic alternate block reassignment

If a defective data block is detected during read, the IDD can automatically reassign its alternate data block.

(12)Programmable data block length

Data can be accessed in fixed-block length units. The data block length is programmable, and can at initializing with a multiple of two for LC/LP and four for MC/MP within the range of 512 to 528 bytes.

(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.

(15)Large capacity

A large capacity can be obtained from 3.5-inch 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.
