Abstract

A data storage device includes a memory device having a plurality of blocks and a controller coupled to the memory device. The controller is configured to determine that an uncorrectable error correction code (UECC) failure has occurred to a block of the plurality of blocks, enable a UECC anti-strike mechanism, and erase the block. The UECC anti-strike mechanism comprises converting a read failure associated with the block to an erase failure. The controller is further configured to retire the block upon determining that the erase is unsuccessful.
