If they work at the hardware level, the filesystem is irrelevant.
What they do, I'm guessing, is try to read the data from bad sectors (one way is to read multiple times and do an average), and then remap the sector to a good one. Modern disks have some space reserved by the manufacturers for this very purpose. Just trying to write to a bad sector will automatically trigger the remap, if enabled, in a way that is totally transparent to the operating system (even when running). It may happen any time. You can see the remap counter using a smart utility, like smartctl in linux.

Spinrite goes way WAY beyond that - I've been using it since version 2 on a PerStor controller. It can actually (usually) recover data from a block that went bad after you wrote to it, and a whole lot more. Read the grc website. Anyone that uses disk systems seriously should have a copy of spinrite in their toolkit.
