ABSTRACT:
A method of correcting an error, which is suitable for use in a storage device. When the error exists in data read from a storage region of a storage medium having the storage region and a spare region and the read data is correctable, the read data is corrected. The number of defective bits included in the read data is detected. Only when the number of the defective bits exceeds and equals a predetermined value, the storage region storing therein the read data is prohibited from being used and an alternate process for storing corrected data in the spare region is executed.
