What the above post meant by "Either the drive can read the bits, can't but is able restore it via ECC, or it can't." is that the drive will either read the wave or it will fail to read the wave and you will get a section of blank audio. I used to have this happen. I would have read errors and open the wave in Sound Forge to see that the wave had breaks in it. It is a problem you cannot fix, you have to re-read the file off the disk.
ECC is something you don't want to have kick in. You want the wave that is on the disk read perfectly the first time.
