Abstract
A first physical location is read to obtain read data. Error correction decoding is performed on the read data to obtain error-corrected data where the error-corrected data includes first error-corrected metadata. Error correction encoding is performed on a first random sequence combined with a second random sequence, concatenated with second metadata. Error correction encoding is also performed on a sequence of zeros concatenated with the first error-corrected metadata to obtain second encoded data. The error-corrected data, the first encoded data, and the second encoded data are summed to obtain migrated data, which is stored at a second physical location.
