I'll prune a bit too, but will backtrack to earlier context, so thanks.

Looks like a not ready error maybe. The only value in your ad1.txt that
looks like it's ever been anywhere near any error threshold is ID# 11,
Calibration_Retry_Count, and its current value is fine. Power glitch?
Are you getting any other hard looking errors in /var/log/messages? Is
fsck happy? It never hurts to run 'fsck -n' whenever you feel the urge.

Only your ad3.txt referred to below shows a (short) test having been
completed and logged. You might check the smartctl -a results after
running at least short tests initially (looks like the long ones will
take 4-5 hours for your 4 drives) as Chuck has since suggested.

I'm not sure of the degree of logging you're having smartd use here, but
these small changes of value, especially up and down by 1 but a long way
from any error threshold, seem to be excessive and relatively trivial
perhaps debug-level detail?, ie most likely nothing of any concern.
I suggest reading man smartctl under '-A, --attributes' and then you'll
know as much as I do about what these may mean, and maybe worry less ..

Do you mean according to that fine-detail attribute changes logging? Or
real read/write/seek etc errors being logged to messages?

None of those reports seem to indicate any problems really, though if
anyone else cares to peek and notices any anomalies, I'm all eyes.
As for temperatures, the readings for all 4 drives seem very cool, but
then it is winter over there .. Temperature Celcius for ad0 to ad3 being
36, 27, 22 and 18 degrees C, each present and worst value well clear of
error thresholds .. did you interprete those values as temperatures?

Might be worth checking that your power supply is up to handling 4 big
drives, but they weren't running more than mildly warm when reported.

These too were running nice and cool, 22 and 18C, when reported. Cf my
40GB laptop drive (at smartctl version 5.36 [i386-portbld-freebsd5.5],
rather more recent than your 5.33 freebsd6.0) this afternoon:
194 Temperature_Celsius 0x0022 100 100 000 Old_age Always - 40
(Lifetime Min/Max 13/49)

Perhaps it wasn't properly warmed up when you ran those reports, but on
the data you've provided you don't have any sort of temperature problem.

Over 70C or so is too hot to touch except momentarily. You're cool :)
