Abstract
On-the-fly error correction is provided using syndromes of a codeword encoded on data storage media. First and second syndromes are generated and a variable prescaler prescales the second syndrome by a field element to produce a prescaled second syndrome where the field element is variable. The error value is determined based on the first syndrome, and the error location is determined based on a comparison between the error value and the value of the prescaled second syndrome. The error value located at the error location is then corrected.
