It probably can't tell.
Reallocation happens by way of the drive controller; the main OS is not
involved, nor even informed unless it specifically asks. I'm not aware of
any way to inquire about the reallocation map - if such a method exists,
it's almost certainly manufacturer-specific and undocumented.

None of them. That's the purpose of reallocating sectors, not just letting
them fail.

That's nice for you, but has little to do with HDD sector reallocation.
