Thank you for contacting Western Digital Customer Service and Support.
The drives have a minimum life of 600K cycles. There is a utility that you can run to alter to a max of 25 seconds, or disable the load/unload cycles the drive performs. It is recommended to alter the load/unload cycles rather than a complete disable.
On their support site I found a program called wdidle3.exe.
The accompanying wdidle3..txt says :

USAGE
WDIDLE3 [/S[<Timer>]] [/D] [/R] [/?]

/R Report current timer.
/? This help info.

Since I do not have a floppy drive on this machine, and after a few hours of unsuccessful fiddling with FreeDos booting from a USB drive, I still have no idea if this helps.
But there is an interesting stuff in the text file. The default is 80, so 8 seconds. That would mean that the drive is sent to park every 8 seconds? The other weird thing is that the maximum is 25 seconds. That would be worse then the number of parks right now. Or am I reading this wrong ?
Anyway, I hope somebody finds this info useful. If not, sorry for spamming...
