Abstract
A disclosed method includes selecting one or more regions having a predetermined size or more in a logical address space of a first memory drive when the first memory drive is partially failed, transferring data of the one or more selected regions to a second memory drive, reading data from another memory drive, which forms a RAID group with the first memory drive, to restore lost data caused by the partial failure, and writing the restored lost data to the first memory drive.
