this is the e-mail i got from hitachi:
The E7K60 was designed more for Blade Servers than laptops. This drive
Advance Power Management disabled, so the drive is constantly spinning
which creates more heat. It can not be enabled. Acoustic Management
not work either.
I have looked into your situation further. The ambient operating
temperature for this drive ranges from 5 Degrees to 40 Degrees C.
I noticed more information as well. The system is responsible for
sufficient ventilation to maintain a surface temperature below 50ºC at
center of the top cover of the drive and below 53°C at the center of
drive circuit board assembly.
We would like you to run a different program so we can see what the
values for temperature are. Two such programs are Active Smart and Hdd
Health. They can be found at the following links:http://www.ariolic.com/activesmart/index.htmlhttp://www.panterasoft.com/
If you can run these programs and provide us with the data it gives
should be able to give you a better answer to your questions.
