This is very incorrect for any mechanical part in your computer.  Moving
parts tend to either wear out from too much use, or freeze up from total
lack of use.  I would imagine that a hard drive that is only powered up
for a few hours at a time once a week will be much less likely to suffer
mechanical failure than a drive that is left on 24/7.

When I was playing around with power management settings on my laptop I
read that hard drives are only likely to survive so many spin up/down
cycles.  I don't recall what the number was but it was at least many
thousands, and my laptop is WAY over that :).

Same here, for my desktop.  I only keep it running because it is quite
often doing something useful, or I (or someone else) may need to access
it remotely.

My desktop is a 3-4 year old dual Athlon that runs nearly 24/7.  I've
had to replace 2 cpu fans so far.  I doubt I would have had to do that
if I only turned it on when I was using it.

There are plenty of excuses to keep a computer powered up 24/7,
longevity isn't one of them :).
