If you like technical papers, you might find this one interesting: 
<http://www.cs.virginia.edu/~gurumurthi/papers/tos06.pdf>.

This paper suggests a maximum internal temperature for modern, 
high-performance disk drives of about 55°C. In particular, they note 
that if only the spindle motor and voice-coil motor (the head 
positioning motor) are considered, a maximum operating temperature of 
45°C is obtained but by factoring in the heat generation of the 
internal electronics, anothe 10°C is added.

I haven't studied it closely, but it's interesting to look at their 
extrapolations of drive temperatures over the future given the 
anticipated growth in drive capacity and speed. It appears some design 
changes will be needed.
