Hi,

I recently bought a MAXTOR STM3320620A (the 300Gb one) that was on
sale on compusa for some $88

The first thing I did with it was running smartmontools on it (http://
smartmontools.sourceforge.net)

sh-3.1# smartctl -a /dev/hda

Looks like this is not a new disk.

It's 9 power-on hours old.

I assume that when the OP said that the FIRST thing he did was to get the SMART data, that it did not take 9 hours to do this. Thus, it looks like a slightly used disk, in other words, not new. Of course, the OP may also have exaggerated about how quickly he got the SMART data from the drive.


There are no reallocated sectors reported, and IMHO, this is the key value
to watch for impending failure.

It's one count that predicts failure. For more information, read the
following paper:

Yes, I had already seen that. From the summary:
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

Summarizing further, 3 out of 4 main criteria for imminent failure are correlated to reallocation.
