Abstract
Automated address mapping is achieved by a system and methodology which automatically reacts to changes in the disk configuration. Prior to utilizing the disk, disk configuration information is provided by the user resulting in a stored configuration table. This configuration table is then used to compute an address translation structure which can be later used to perform actual address mapping operations. Utilizing this address translation structure, in combination with appropriate formulas, address mapping from a logical block address, provided by the host computer, to a surface-track-sector address (STSA) is easily accomplished. By having the actual address translations dependent upon the configuration table, the system and method automatically reacts to changes in the disk configuration.
