What is SMART anyway? I recently had an error message from SMART during
my initial boot. I don't remember the exact words, but it basically
said that my drive was going to fail soon and suggested immediate
replacement.
Is SMART just another type of dsik check utility (like scan disk)?
Also, is my drive really BO? I haven't had an error message for about a
month. I am planning on replacing the drive with another one, but could
I use the "SMART says it's bad" drive for storage or will it cause
problems in the long run?
Modern disks have spare sectors and map bad ones to spares automatically.
This means that you never see a bad sector until the disk is in really bad
shape, so it seems to fail without warning.
SMART is intended to deal with this by providing you a warning when the disk
is starting to show signs of impending failure--it is built into the disk
and monitors a bunch of indicators, including the percentage of the spare
sectors that have been used--when it tells you that a disk is on the way
out, it's not a guarantee of impending failure--the disk may run in its
current condition for a very long time--but you were warned.
That message is actually from your computer's firmware--SMART doesn't say
"this drive is about to go", it just reports a bunch of numbers that if you
have turned on the capability get checked during the POST routine and if
the combination is such that your computer manufacturer's programmers have
decided that they indicate that the disk is having problems the machine
will give you the error message you see. If it came up once and not again
it's probably a fluke--something went wrong during power up that one time.
If it's happening most times that you power up then I'd replace the drive
at my earliest convenience. If you haven't shut the machine down and
rebooted since you saw it you should and see if it comes up again--if it
does, assume that the disk is about to go.
