Abstract
Methods and arrangements to handle non-queued commands for data storage devices, such as Parallel and Serial ATA hard drives, are disclosed. Embodiments may comprise a host and/or a data storage device. The host and data storage device may form, e.g., a handheld device such as an MP3 player, a cellular phone, or the like. The storage device may comprise a new method of responding to a non-queued command while the storage device may be processing a queue of commands. In many embodiments, the method involves processing queued commands until the drive receives a non-queued command that requires immediate processing by the drive. In many of these embodiments, the drive will respond in a new manner to process the non-queued command, the end result having no or minimal impact on host system operation.
