Abstract:
A method for preventing cold temperature induced damage in a direct access storage device (DASD) comprising the steps of: measuring a temperature of the direct access storage device (DASD); comparing a predetermined minimum cold temperature with said measured temperature; and starting the direct access storage device (DASD) responsive to said measured temperature being greater than or equal to said predetermined minimum cold temperature; heating said direct access storage device (DASD) responsive to said measured temperature being less than said predetermined minimum cold temperature by applying a current to an actuator in said direct access storage device (DASD) and said applied current having an opposite direction as a normal current for moving a transducer head onto a disk surface; and identifying a predefined time interval, and disabling said applied current responsive to said identified predefined time interval.
