    • A method and computer program product for sending a data request from a host bus adapter logic processor to a hard disk drive, setting a standard time out period for receiving a reply from the hard disk drive, sensing vibration in the hard disk drive, sending a vibration alert signal from the hard disk drive to the host bus adapter logic processor in response to the sensed vibration exceeding a predetermined amount of vibration, and, in response to receiving the vibration alert signal from the hard disk drive, the host bus adapter logic processor establishing an extended time out period for receiving the reply. The rotational vibration sensor used by the hard disk drive for repositioning the read/write head may also be used to sense the vibration and form the basis for the vibration alert signal, such as a vibration error code. By extending the time out period during high vibration events, the hard disk drive can ride out the event without being tagged as having failed. Accordingly, the hard disk drive can then be available for use following the high vibration event.
    • 一种用于将数据请求从主机总线适配器逻辑处理器发送到硬盘驱动器的方法和计算机程序产品,设置用于从硬盘驱动器接收回复的标准超时周期,感测硬盘驱动器中的振动,发送 响应于感测到的振动超过预定量的振动,从硬盘驱动器到主机总线适配器逻辑处理器的振动警报信号,并且响应于从硬盘驱动器接收到振动警报信号,主机总线适配器逻辑处理器 建立收到答复的延长期限。 用于重新定位读/写头的硬盘驱动器使用的旋转振动传感器也可以用于感测振动并形成诸如振动错误代码的振动警报信号的基础。 通过在高振动事件期间延长超时周期,硬盘驱动器可以摆脱事件而不被标记为失败。 因此,硬盘驱动器随后可以在高振动事件之后使用。
