Title: Method and apparatus for preventing cold temperature induced damage in a disk drive

Abstract: A method and apparatus are provided for preventing cold temperature induced damage in a direct access storage device (DASD). A temperature of the direct access storage device (DASD) is measured and compared with a predetermined minimum cold temperature. The direct access storage device (DASD) is started responsive to the measured temperature being greater than or equal to the predetermined minimum cold temperature. A warning indication is provided to the user responsive to the measured temperature being less than the predetermined minimum cold temperature. A microcode routine is stored in a random access memory (RAM) in the DASD. The microcode routine is performed for heating the direct access storage device (DASD) responsive to the measured temperature being less than the predetermined minimum cold temperature.
