As the remaining capacity of the HDD was getting low, I replaced it with a 6TB one from 4TB.
It seems that a new function called Intellipark (automatic hdd head parking) has been added to WD HDDs, which increases the number of round trips (load and unload cycles) of the HDD head.
Old WD HDD (or another maker hdd) : 1.5 times/hour
New WD HDD: 16 times/hour
It has increased by more than 10 times.
If I use it 20 times per hour for 8 hours a day, it will exceed 300,000 times in about 5 years, which will be the end of the product's life.
I want to disable Intellipark somehow, but it seems that I can't.
