  • Hard disk drive availability following transient vibration
    Patent number: 8495256
    Abstract: 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.
