If you run badblocks or e2fsck you'll find the application asks to write data to the disk, at the end of the run. Yes, the drive's firmware should manage badblocks transparently to the filesystem, but I have observed in hdparm output reallocations of badblocks do not happen in real time. Perhaps the filesystem level badblocks list which is LBA based, acts as an intermediate step until the hardware triggers a reallocation? Not sure. :-/
