T.E.C. & S.M.A.R.T.
The interpretation of the T.E.C. and the S.M.A.R.T.
The T.E.C. stands for "Threshold Exceeded Condition" and
basically means a failure. When Hard Drive Inspector reports "Nearest forecasted
T.E.C." you should read "Failure date".
Yet first of all, you should know that the
been approved by the HDD manufacturers as nothing but an advisory argument. In
other words, it is reliable, but none can be 100% sure in this.
Hard Drive Inspector predicts T.E.C. on the basis of the
values of the S.M.A.R.T. attributes and the speed of their changes. However the
prognosis of the T.E.C. has to be treated with care because there are several
well-known facts occurred with the HDDs of some manufacturers, when the values
of the S.M.A.R.T. attributes slump right after turning the HDD on, and then
rectify. Therefore, it is not worth to worry about the insignificant attribute's
changes for a new HDD. There also are some cases, when a HDD continues working
even if the attribute's value is less than its threshold value.
Generally, the main conclusion of this topic is not to hurry
when Hard Drive Inspector shows a change of the value or/and a date of T.E.C.
becomes closer. It is just a signal for you to watch out the attributes for a
few days. At that, if the falling of the attribute's value stops, it's all right
for a while. In this case, the T.E.C. date will be postponed.
Nevertheless, if the falling of the attribute's value
persists, it is strongly recommended to backup all valuable data on the HDD and
replace it by another HDD as soon as possible.
S.M.A.R.T. may be however a useless technology in prevention
