    Hitachi E7K60, . . , . , .

    Dear Sir,

    Thank you for contacting our Hitachi Technical Support Center regarding
    your enquiry relating to the brief sound that emanates from our drives.

    We suspect that the occasional 'sound' you are hearing is the Idle Time
    Function that has been introduced on our latest drive designs as a
    reliability enhancement. You need not be alarmed by this,

    This "sound" is due to a brief but deliberate head arm movement every so
    often. This has been added to maximise the reliability of our disk drive
    products. This function is only invoked if an extended period of inactivity
    is detected, so has no impact on active performance. [It is bad to leave
    the heads hovering over the same data track unnecessarily].

    Even after a period of time of activity the Idle Time Function can be
    implemented as the Idle Time Function is a cumulative function.

    The level of sound emitted may vary from one drive to another and as such
    this should not give rise to concern or be considered an impending failure.

    Please be assured that this drive design is one of the quietest drives, at
    this data density, in the industry.

    We trust this information will be of use and help you to resolve your
    problem(s).

    Best regards

    Hitachi Technical Support Center
