my questions are:
is this disk really "degrade" or not?
how O.S. can predicate disk going to failure?
do I need replace this disk now?
I understand that the drive electronics can check things such as the time it takes to read a sector, number of failures per read, retries before success etc.. This information gets processed and reported to the OS via SMART as some others have replied.
But I really just want to say that within one day of getting SMART errors, my disk failed.
FWIW, Smart started noting problems on my laptop drive, and the manufacturer accepted a Smart report as sufficient to warrant a replacement drive being fitted under warranty.
