So you think that there is *no* information from the PRML "read channel" that is also input to the ECC correction algorithm? You think the ECC correction is done purely and only on the digital data in the drive's buffer ignoring any and all information from the read channel about the "quality" of that data? Even 40 years ago "signal quality" information from the "read channel" was used by ECC algorithms to correct digital data. *** Hale Landis *** www.ata-atapi.com ***
