The idea is grab the data on a marginal block before it goes bad permanently. You can try a number of different things on a soft read error: a) remap on the very first read error, b) keep track of the number of soft read errors and remap after some magic number, c) rewrite the data and see if the soft read error goes away, d) a combination of b) and c), or e) do nothing. Each option has its pros and cons. But it has been years since I last looked at this stuff and Quantum may be using something totally different.
