    • A method of converting a hybrid hard disk drive (HDD) to a normal HDD when a system is powered on depending on whether the total number of defective blocks in a non-volatile cache (NVC) exceeds a predetermined threshold. The method of converting a hard disk drive (HDD) from a hybrid HDD to a normal HDD where the HDD has a normal hard disk and a non-volatile cache includes the steps of determining whether a mode conversion flag is enabled during a power-on period. When the mode conversion flag is enabled, operating the HDD as a normal HDD. When the mode conversion flag is disabled, determining whether an operating mode of the HDD is a normal mode or a hybrid mode. When the operating mode of the HDD is in the normal mode, the HDD operates as a normal HDD. A determination is made when the HDD is in the hybrid mode as to whether the total number of defective blocks in the non-volatile cache is greater than a predetermined threshold. The HDD is operated as a hybrid HDD when the total number of defective blocks is not greater than the threshold. The mode conversion flag is enabled and the HDD is operated as a hybrid HDD when the total number of defective blocks is greater than the threshold.
    • 根据非易失性高速缓存(NVC)中的缺陷块的总数是否超过预定阈值,在系统通电时将混合硬盘驱动器(HDD)转换为普通HDD的方法。 将硬盘驱动器(HDD)从混合HDD转换为HDD具有普通硬盘和非易失性高速缓存的普通HDD的方法包括以下步骤:确定在上电期间是否启用模式转换标志 期。 当模式转换标志被使能时,将HDD作为普通HDD操作。 当模式转换标志被禁用时,确定HDD的操作模式是正常模式还是混合模式。 当HDD的操作模式处于正常模式时,HDD作为普通HDD操作。 当HDD处于混合模式时,确定非易失性高速缓存中的缺陷块的总数是否大于预定阈值。 当缺陷块的总数不大于阈值时,HDD作为混合HDD操作。 当缺陷块的总数大于阈值时,模式转换标志被使能并且HDD作为混合HDD操作。
