摘要
A defect detection and correction system includes a decoder module configured to decode data received from a data storage device and output the data and a plurality of confidence indicators associated with respective bits of the data. A digital defect detection module is configured to compare each of the confidence indicators in a window of W bits of the data to a confidence threshold, identify a number of bits in the window of W bits as defective based on the comparison, mark all of the bits in the window of W bits as defective if the number of bits is greater than a bit threshold, and generate a defect indicator identifying the window of W bits as defective.
