摘要： A disc drive typically contains at least one disc which is divided into sectors. The method of eliminating reassignments involves copying data stored at one sector (referred to as a moving sector) to another sector (referred to as a moving spare), and assigning the logical address associated with the moving sector to the moving spare. The elimination process is repeated until the reassignments are eliminated. Verification of the data copied is conducted to ensure data integrity. Furthermore, the elimination process is preferably executed only when the disc drive is in an idle mode. Records are kept and updated as the process is carried out so that the process can be continued even if interrupted.

摘要： A method to improve drive read performance in a disc drive includes powering-up a disk drive, reading reassigned sectors data from a reassign spare pool, and storing the reassigned sectors data in a reassigned cache segment. This method also includes initiating a read request, detecting a reassigned sector within the read request, and determining whether the requested sector can be located in the reassignment cache. If the reassigned sectors are found in the cache, then the method includes transferring the reassigned sector data from the reassignment cache to the read buffer or directly to the requesting host computer. If the reassigned sectors are not found in the cache, then the method includes seeking to the reassignment spare pool to fetch as much reassigned sectors data as the reassignment cache can hold. In another embodiment, the reassigned sectors data stored in a reassignment cache segment is located in a buffer.
摘要翻译：一种提高磁盘驱动器的驱动器读取性能的方法包括加电磁盘驱动器，从重新分配的备用存储池读取重新分配的扇区数据，以及将重新分配的扇区数据存储在重新分配的高速缓存段中。该方法还包括启动读取请求，检测读取请求内的重新分配的扇区，以及确定所请求的扇区是否可以位于重新分配高速缓存中。如果在缓存中找到重新分配的扇区，则该方法包括将重新分配的扇区数据从重新分配缓存传送到读取缓冲器或直接传送到请求主机计算机。如果在高速缓存中没有找到重新分配的扇区，则该方法包括寻求重新分配备用池以在重新分配缓存可以保持时获取尽可能多的重新分配的扇区数据。在另一个实施例中，存储在重新分配高速缓存段中的重新分配的扇区数据位于缓冲器中。
