Abstract
The present invention may be embodied in a cache control method for caching disk data in a disk drive configured to receive commands for both streaming and non-streaming data from a host. A lossy state record is provided for memory segments in a cache memory. The lossy state record allows hosts commands to be mixed for streaming and non-streaming data without flushing of cache data for a command mode change.
