摘要

PURPOSE: An operation method of a hard disk drive and devices performing the same are provided to increase read performance by reading the data without success of a disk.;CONSTITUTION: An HDD(Hard Disk Drive) receives a writing command DRM from a receiving command(10). The HDD receives a write command from the host(S10). The HDD detects defect of a sector of detected data. The HDD reallocates the detected sector to a spared sector(S30). The HAD writes the data in the spare sector.(S40).;COPYRIGHT KIPO 2013;[Reference numerals] (S10) Receiving a writing command; (S20) Detecting defect in a sector in which data is written; (S30) Allocating a sector to a spare sector again; (S40) Storing data in a buffer
