    摘要: A data storage device that includes a magnetic storage device and a non-magnetic nonvolatile storage device that measures a hit rate of read/write commands that result in accesses to the non-magnetic nonvolatile storage device, and adjusts a length of a time period, such as an idle time, based on the hit rate. The duration of the time period can be set each time the magnetic storage device is accessed. Upon expiration of the time period, if the magnetic storage device has not yet been accessed, the magnetic storage device is changed from a higher power consumption state to a lower power consumption state.

    摘要: An apparatus, system, and method for automatic unthreading and storage of storage media helps prevent damage to the media, which can otherwise occur when the storage media is left threaded in a storage media drive over an extended period or under adverse conditions. A sensing device may generate a signal or a detector may receive a signal indicating that a predetermined period of time has lapsed or that some other criteria has been met indicating that the storage media should be removed from the storage media drive. An unthread module in the storage media drive receives the signal and automatically unthreads and stores the storage media. A location on the storage media can be marked by the unthread module prior to unthreading such that the media may be returned to the location upon rethreading.

    摘要: A power-saving method adapted in a hard disk in a computer system having a CPU and a memory module is provided. The power-saving method comprises the following steps. A data-to-be-written is transferred from the memory module through the CPU to the hard disk filter. A determining module is provided to determine whether a data access frequency of the computer system exceeds a threshold value. When the data access frequency exceeds the threshold value, the determining module further determines whether a request-queuing time exceeds an idle-mode activation time. When the request-queuing time exceeds the idle-mode activation time interval, the data-to-be-written is stored in a temporary storage location by the hard disk filter. When a condition of the computer system is satisfied, the data-to-be-written is written to the hard disk to extend the duration of an idle-mode of the hard disk. A power-saving operating system is disclosed herein as well.
