It's 9 power-on hours old.

And he has power cycled the machine 9 times.

The raw numbers are sometimes very strange; in that case look at the
VALUE and WORST numbers, which should be 100, 200, or 255 at best.

It's one count that predicts failure. For more information, read the
following paper:
@InProceedings{pinheiro+07,
author = {Eduardo Pinheiro and Wolf-Dietrich Weber and Luiz
Andr\'e Barroso},
title = {Failure Trends in a Large Disk Drive Population},
booktitle = {5th USENIX Conference on File and Storage
Technologies (FAST '07)},
OPTpages = {},
year = {2007},
month = feb,
annote = {Reports data on the correlation of various hard disk
properties (in particular SMART output) with their
failure probability, based on $>100,000$ drives
installed at Google. The paper mentions that drive
model, manufacturer and vintage plays a role, but
does not give data on model and
manufacturer. Utilization and temperature did not
play a big role in failure probability (but the
drives were not run at really high temperatures (few
above 45C). From the SMART data, scan errors,
reallocations, offline reallocations and probational
counts were significantly correlated with failure
probability, whereas seek errors, calibration
retries and spin retries had little
significance. But on more than half of the failed
drives, the four strong indicators mentioned above
had no counts.}
