ONLY when you write to a bad sector, OR a SMART offline/online surface scan
test hits the bad sector, whichever happens first. Before that, many drives
will give you an ECC error back when you try to read the sector.
So, write to it first, or do a SMART surface scan. If it goes away, the
drive has remapped it. If the drive is part of a RAID array, readd it to
the array and see if it syncs properly.
Remember, SMART features are meant to be used in a SMART happy system. I.e.,
one where you did NOT disable SMART on the BIOS because "it slows down the
disc" as most looser^H^H^Hgamer magazines preach, and where you use
something akin to smartd to perform offline data gathering and offline tests
often.
