EXECUTING METHOD FOR ERROR RECOVERY PROCEDURE

摘要

PROBLEM TO BE SOLVED: To provide a method/device which can assure execution of an ERP (error recovery procedure) up to its last step regardless of the time needed up to the time-out of an instruction and can more surely recover an error. SOLUTION: A disk device carries out an ERP up to its last step or until an error is recovered with no interruption when a reset instruction is received during execution of the ERP. In another mode, the disk device stops execution of the ERP and also holds the number K of the step whose execution is over right before reception of a reset instruction when this instruction is received during execution of the ERP. Then the disk device successively carries out the ERP from the (K+1)th error recovery step when a retry instruction is received.
