Abstract:
A method that automatically adjusts a host protected area of a target hard disk drive relative to a master hard disk drive using a basic input/output system (BIOS), the method comprising the steps of:reading a Boot Engineering Extension Record (BEER) and Directory of Service from the target hard disk drive; verifying if there is a valid report geometry for the target hard disk drive; determining if the master hard disk drive and the target hard disk drive have a same size; calculating the size difference between the master and target hard disk drives; adding the size difference to the host protected area Start field in the BEER; retrieving a number of Service Entries from the BEER; adding the size difference to a Service Area Start field of all Service Entries updating a Reported Sectors/Device field of the BEER to the target hard disk drive size; calculating a checksum for the BEER and Service Entries; saving the calculated checksum to a checksum field; and writing the updated BEER and Service Entries to the target hard disk drive.
