ALL drives have hiccups when there's absolutely
nothing wrong with them. What are the manufacturer's error figures?
Expect at least one error every two or three complete passes of pretty
much every large big disk nowadays?

i don't expect any SMART error at all and if one hits after years of
uptime fine that the drive don't fail completly - but would i trust it? no!

I have multiple drives (Hitachi) which have developed around 3 to 10
reallocated sectors, and then just continue to work for years, not increasing
those further. Throwing them away would be uneconomical. Not always a
reallocated sector is a sign of impeding failure, what you need to look for is
if there is more than one, and the count is increasing quickly.

Concur. I do not replace drives for reallocated sectors until they reach 
double digits.  Modern drives are expected to do this.

Generally though, if you are way too concerned about individual drive failures,
it could be a sign that you do not have a robust enough backup scheme in place.

Heh.
