Abstract
Methods, non-transitory computer readable media, and computing devices that determine when a storage element of a data storage device has failed. Address(es) mapped to the failed storage element are identified, when the determining indicates that the storage element has failed. Data corresponding to the address(es) is regenerated according to a data loss protection and recovery scheme (e.g., a RAID scheme). The regenerated data is written to other storage element(s) of the data storage device in order to remap the address(es) to the other storage element(s). This technology allows a data storage device (e.g., an SSD) to be repaired in-place following a failure of storage element(s) (e.g., a die) of the data storage device. Advantageously, entire data storage devices do not have to be failed with this technology as a result of a failure of an individual storage element, thereby reducing data storage device failure rates and associated overhead.
