Abstract
A method of assigning replacement rows and colums in a two dimensionally redundant array in which if the number of failures along a row exceeds the number of remaining redundant columns, then replacing that row with one of the redundant rows. The process is repeated in the opposite direction with the number of remaining redundant rows and columns being properly decremented. The process of reversing directions continues until the above condition is no longer satisfied.
