Abstract: Apparatus and method for managing data in a hybrid data storage device. In some embodiments, the storage device has a hard disc drive (HDD) controller circuit coupled to non-volatile rotatable storage media and a solid state drive (SSD) controller circuit coupled to non-volatile solid state memory. A local volatile memory has separate HDD and SSD partitions respectively accessible by the HDD and SSD controller circuits. A top level controller circuit performs a cleaning operation to transfer a data set from the non-volatile solid state memory to the rotatable storage media by issuing a read command to the HDD controller circuit to retrieve the data set to the HDD partition, transferring the data set from the HDD partition to the SSD partition, and issuing a write command to the SSD controller circuit to write the data set from the SSD partition to the non-volatile solid state memory.

Abstract: A data storage area of a data storage device can be used to communicate information between the data storage device and an external device or software. In some examples, configuration data stored within the data storage area can be used to determine a subset of data to copy or move from a first data storage medium to a second data storage medium. The data storage area can be a unique partition and the data storage device can locate partition information to determine a location of the partition. The data storage device can then use the partition to store data for two-way communication between the data storage device and an external system, device, or software.

Abstract: A data storage device includes a solid state data storage medium, a set of related data blocks and a controller. The set of related data blocks are non-contiguously stored on the data storage medium and have an original write sequence. The controller, responsive to a defragmentation request, maps the physical block addresses of the set of related data blocks to contiguous logical block addresses in the original write sequence while maintaining the non-contiguous physical block addresses of the set of related data blocks on the data storage medium.
