Whats the idle timer of WD REDs?

I’m aware that there was a bug in the firmware which sends the heads of older REDs into parking after 8 seconds.

From what I know with newer drives that’s no longer the case. Yet I’m wondering has the idle timer been switched of completely or just gotten a longer timespan? All I could find on the net were posts regarding the old 8 sec value.


So far it seems that it depends.
There have been some older WD Red 4TB around where idle3 timer was still set to 8 sec.
To verify if anything goes wrong you should monitor the LCC value of SMART if it starts increasing.
