SMART won't tell you exactly how large the spare sector map is but it will tell you how much of it is used. Combined with the trigger information as to percentages for a SMART failure and you should be able to determine with a fair amount of accuracy just how big the spares are. | |

| Oct 26, 2016 at 5:16 | comment | added | enigmaticPhysicist | I have heard of SMART. Does it specifically tell you how many sectors are left in the spare sector pool? | |
| Oct 25, 2016 at 23:13 | comment | added | sawdust | That's a confusing and low-quality article used for a citation. I've done extensive work with (older) disk drives and controllers, and the explanations made little sense (and the bad grammar doesn't help). AFAIK zero-filling a drive doesn't repair or fix bad sectors. A much better article is Bad sector remapping | |
