Abstract
Provided are a method, system, and program for performing error correction in a storage device having a magnetic storage medium. A plurality of zones are defined in the magnetic storage medium, wherein each zone comprises a plurality of addressable locations in the magnetic storage medium. A determination is made as to whether a change of a signal-to-noise ratio for one subject zone of the plurality of zones exceeds a threshold. An operation is performed to improve the signal-to-noise ratio with respect to the subject zone of the magnetic storage medium after determining that the change of the signal-to-noise ratio exceeds the threshold.
