Hi,
while imho 56 degrees Celsius is definitely "too hot" for a disk, it would be interesting if this is the permanent temperature of your disk during the day or just a peak temperature during high load.
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.
