It sounds like you've still missed a bit. The MTBF
of 136
years doesn't mean that your drive might last 136 years on
average, nor does it mean that if you buy 136 drives you
should expect one failure per year on average.
There's a longer discussion on Wikipedia:
http://en.wikipedia.org/wiki/MTBF
Do you have any disagreements or other interpretation of what's there?

Most modern drives support SMART ... and some of them
(but not all)
even correctly count and report the number of power cycles.
UBCD has a range of disk diagnostic tools, modern Linux variants
have smarttools, you can track down any number of disk monitoring
tools for Windows.
Lately I've been wondering about just how well SMART is monitored.
Can the computer still read it if the drives are in a RAID?
