The bad_blocks entries record sectors where I/O failed, which
indicates that the device-internal remapping did not succeed
at that time.

`rectify` does not assume a permanently bad or fixed LBA. Its
purpose is to trigger an additional rewrite, giving the underlying
device (e.g. FTL or firmware) another opportunity to perform its
own remapping.
