Abstract
Devices, systems, and methods with proactive data loss notification and handling. A data storage device includes a memory and a controller. The controller includes a processor and controller memory. The controller memory stores a set of instructions that, when executed by the processor, instruct the controller to: detect an uncorrectable error correction code (UECC) during an internal data movement process of the storage device memory, modify a metadata field associated with a logical block address corresponding to the UECC, inform a host device about the UECC, and determine whether data stored in at least one adjacent region to the logical block address is lost.
