Abstract
A disk drive has on-board soft error recovery procedures for recovering data following a soft error, and the capability to selectively disable or limit this feature. Preferably, a set of data storage devices are used to store heterogeneous data, i.e., to store some alphanumeric data, and some multimedia data. If a disk drive is selected for storage of multimedia data, the soft error recovery is disabled, and soft errors are simply transmitted to the host system as data. If each disk surface may be independently allocated to data of different types, soft error recovery may be independently disabled for each disk surface.
