In my experience, no drive remaps bad sectors on reads, only on writes. This
kinda makes sense, since if you're writing to a block, you obviously don't
care what's (supposed to be) there and it's completely safe to remap.
Now, if they're failing to remap on write operations, they've probably run
out of spare blocks and are truly dead.
