I've been running my hard drive 24/7 for over 2 years with narry a problem
(Of course now that I say something...). Actually it was discovered not
too long ago that when a hard drive spins for quite a bit of time, it
tends to cause the lubricant molecules to link together differently
forming a basic sort of plastic (Polymer). When the platter stops, the
plastic stuff hardens. It doesn't completely prevent the platter from
spinning, however it provides a force of resistance when the platter spins
up again. As heat and friction is generated from the platter spinning up,
the plastic re-liquifies and does it's lubricating job again.

Also another thing to think about is that prime.exe writes to the drive
every 30 minutes. Can you imgaine how bad that is for a drive to spin up
and spin down every thirty minutes? It's like being in stop and go traffic
24x7. You'd trash your car... 

>From what I recall (and correct me if I am wrong), the MTBF of an average
hard drive is around ten years of continuous usage. Quite honestly, unless
you want to save a few bucks a year in power consumption, I wouldn't worry
about it...
