10.13.1 Auto Reassign Function The sectors that show some errors may be reallocated automatically when specific conditions are met. The spare tracks for reallocation are located at regular intervals from Cylinder 0. The conditions for auto-reallocation are described below. Non-recovered write errors When a write operation can not be completed after the Error Recovery Procedure (ERP) is fully carried out, the sector(s) are reallocated to the spare location. An error is reported to the host system only when the write cache is disabled and the auto reallocation fails. If the number of available spare sectors reaches 16 sectors, the write cache function will be disabled automatically. Non-recovered read errors When a read operation fails after a defined ERP is fully carried out, a hard error is reported to the host system. This location is registered internally as a candidate for the reallocation. When a registered location is specified as a target of a write operation, a sequence of media verifications is performed automatically. When the result of this verification meets the criteria, this sector is reallocated. Recovered read errors When a read operation for a sector fails once and then is recovered at the specific ERP step, this sector of data is reallocated automatically. A media verification sequence may be run prior to the relocation according to the predefined conditions. Travelstar 5K100 (Serial ATA) Hard Disk Drive Specification 68
