Ace was not suggesting that you replace the heads because firmware needs to detect that there are different heads, they suggested it because the current heads could not write to the service area. If your current heads are original it's possible the write heads are weak. In the case of weak heads a fresh donor might be able to write to the service area. If you have donor heads in there already, it's possible another pair will line up more like the original and be able to write to the service area. The close tolerance the heads operate at mean one donor can sometimes work better than another. The manufacturing process does not produce exact same alignment at this tolerance. Consider the reason for head adaptives that are specific to each drive and it starts making more sense. Hope that helps a little.kilgor":1xucuwb5 said:well as far as I know head conditions are good, but to rebuild these files they told me to replace heads, so disk can rewrite its new system files. I was hoping to trick the disk that I reinstalled new heads so disk can rewrite system files
