Hello,

There is a Z5K500 (hts545050a7e680) HDD in my brand new laptop, and I observed a relatively fast LLC ramp up since its first usage: it went up to 860 in only 3 days. My question: is this normal ? Is there maybe a tool for this model to modify the head parking behaviour similarly to the wdidle tool ? Unfortunately the latest HGST "feature tool" doesnt even detect this drive.

Thanks in advance.

ps: I see, there is a 600K limit on LLC in the specs, that means 5.4 years of usage counting with a 300/day average, but still, it seems to me too much.

If there is no other way, try quietHDD:
