Abstract
Examples include a data storage device controller with one or more electronic processors configured to receive a write command that includes host data to be written to a memory, and service the write command by controlling the memory to write the host data to a primary update block of the memory and a secondary update block of the memory. The one or more electronic processors perform a first targeted enhanced post-write read (EPWR) operation on the primary update block by identifying one or more valid data regions of the primary update block, selectively performing EPWR on the one or more valid data regions of the primary update block, and in response to determining, based on a result of the EPWR performed on the one or more valid data regions, that the one or more valid data regions do not include an uncorrectable error, releasing the secondary update block.
