Simply, the head parking
problem is an artifact of one of the features of the Western Digital Green line. Basically, every time a hard drive takes its reading arms off the platters, it ticks a counter. On normal hard drives, the only normal time the arms were taken off the platters was during power down and power up, so head parking readings became a good indicator of how many times the hard drive has been powered on and off. Counting how many times hard drive power on or off is important, as the most stressful time for a hard drive is during this operation.
With the Green line, Western Digital started parking the heads after a period of inactivity in order to save power. It still counted these head parking activities as before, however, so the Green hard drives showed way too many head parks, and many S.M.A.R.T. programs threw up red flags.
There have been plenty of theoretical discussions whether these head parks are actually causing undue wear on the hard drives or if it is just bad reporting, and the arguments go both ways. However, I haven't seen a large-scale study done to show either case. Can maybe others chime in with (admittedly very unscientific) anecdotal evidence? I have owned one WD Green and haven't had any problems with it.
I agree with you.But no, an expansive number of drives stop their heads consequently paying little heed to what you set in the power choices, and they utilize pointlessly forceful conduct like stopping after just 8 seconds of idleness. I have a major issue with this in light of the effect it has on the drives acoustics and responsiveness. I'm attempting to make sense of if there is any issue with steady head stopping in applications where those two elements are not an issue.
