(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,
(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
(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
(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.
