Thanks for answering me AGAIN
I am trying to figure out what does DAC values mean or stand for, it they are a response from the HDD to the different biasing currents of the T4 test, and if the ideal value for them is 65000 or that value changes with diferent HDD capasity, model, etc..
The observation about the HEx value corresponding to each of the different levels of biasing current to each of the heads (25, 50, 75, 100, 125, 150 , 175 and 200)mA was pretty linear when I attempted to graph it; making possible to do some reverse engineering on this T4 test. "purely my observation" nothing more.
