Yes, if data is actually unrecoverable (as happened in my notebook's
hard disc: 3 bad sectors at the time of replacement, lost a video) the
drive will kick up a fuss-load of ATA errors, which will be reported all
over dmesg. (If you see any of them, these messages will indicate the
*logical* block(s) for which the read failed, but I don't know how to
map this data back to specific file-system entries.) In the case here
the drive probably read back the data after writing to check it, found
the media wanting, wrote it elsewhere, and blacklisted the sectors.
