A low-level format (using IBM DFT) is going to *silently* remap bad parts of the disk. It's only going to complain once it's no longer possible to remap the bad sectors. So, just because the low-level format doesn't complain does not mean that there is no media degradation! Also, many people seem to be correlating it to heat, and possibly to flaws in IBM's implementation of glass platters in these drives.
