   Actually, that is the key point.  Hitachi's "Endurastar" brand is 
designed for applications probably most people on this list have in mind 
when they are looking to put a 2.5" hard drive in their box.  However, all 
of the much more common "Travelstar" branded drives are designed for (and 
I quote from Hitachi's product specifications) "typical mobile system 
conditions" which it details as:
 	* Less than 333 power on hours per month.
 	* Seeking, writing, and reading (i.e. active) operation is 20% of
 	  power on hours.

   Other hard drive manufactures may make similar distinctions between 
their models.  I did a quick check of Toshiba's web site and they aren't 
nearly as specific of how they expect you to use their drives.

   I'm curious where you got your Endurastar drive from, though, as it 
doesn't seem than anyone sells them directly to consumers.
