Abstract
Systems and methods suitable for assisting data storage on a solid-state mass storage device by furthering interaction between a host and the solid-state mass storage device. The method includes providing data in a target block from a solid-state mass storage device to a host computer system, analyzing the data to identify valid and invalid data of the data in the target block with the host computer system, removing the invalid data, reformatting the valid data into a new data structure with the host computer system, writing the new data structure to the mass storage device, and marking the data in the target block as invalid.
