Abstract
A control module includes an encoder module, a detector module, a mapping module, and a difference module. The encoder module receives data, and based on the data, generates a first code word for drives. The drives are associated with a storage system. The detector module detects an addition of a second drive. The encoder module generates a second code word for the second drive. The mapping module: maps physical locations of the data in the drives to logical locations of the first code word; assigns a predetermined value to a logical location corresponding to an unused logical location; and based on the predetermined value, assigns the unused logical location to the second drive. The difference module generates a third code word based on each of the first and second code words. The encoder module, based on the first and third code words, generates a fourth code word for all drives.
