Hi all !!!
i own two Hitachi 7k250 PATA 8mb cache 160gb. I had overclocked barton, so temperature in my case was about 40 C (maybe little more). I realized that i do not need so powerful CPU, so i put him on default settings, and that cause temperature to fall to 34 C.
AND MY DRIVES NOW DO NOT MAKE MORE SELFTESTING SOUNDS !!!
i was really surprised by that, so i overclocked my barton, and selftesting was here again...
i put barton on default and drives are again quiet as tomb.
so result is, that cat maowing and sawmill sound is probably done only if temperature is above some level (maybe 40C ?!?)
