[Bug 628134] [NEW] Hard disk high temperature / load cycle count

[SolidSlash]

Public bug reported:

As requested, I'm reporting this bug. I'll try to include all the needed
information here.

The default aggressive APM / AAM setting ( =254 ) does a fine job on the load_cycle_count rising issue but actually makes the HDD run really hot.
FYI, on Windows 7 I have set APM = 231 and AAM = 128 and the temperature is lower ( about 41 C comparing to 50 C on Ubuntu with the default APM = 254 ) and surprisingly there's NO load_cycle_count rising problem. The disk simply doesn't click at all. While on Ubuntu, if I lower the APM and AAM values ( 231 & 128 - just like on Windows ), the hdd gets indeed cooler but there comes the load_cycle_count issue - it raises about 1 point every minute.
