So I use pfSense and searching into timeout errors where FreeBSD ejects a blue western digital laptop drive I have came across the wdidle3 util and the wd5741 designed specifically for the WD Red Drives. I have figured out (from reading) that the wd5741 util sets the (on the red drives) Intellipark feature to 300 seconds.
What is the deal with this? I have blue drives in laptops that are up to 1302656 parks that were set to something like 4 seconds. How is this supposed to help at all? Does it save the head electronics? I get that if the drive is in the laptop it could save it during a drop or something.
But here is the bigger question? Why are they parking WD Red drives? I still have yet to look at my array of 4TB reds at home but I am sure they are parking after 300 seconds.
I had to disable parking on my pfSense (at least I think, another month+ to test) so it would stop detaching the WD blue drive ( I do have other solutions in mind).
Back in the old days you would HAVE to park a drive head before shutdown/movement of the drive, but what does parking after 300 seconds do for me or the drive?
Also:
Why does hdparm have this in its man page:
A setting of 30 seconds is recommended for Linux use.
Permitted values are from 8 to 12 seconds, and from 30 to 300
seconds in 30-second increments. Specify a value of zero (0)
to disable the WD idle3 timer completely (NOT RECOMMENDED!).
Why is it "NOT RECOMMENDED!"
I get that setting to 0 on the WD--EZRX drives seemed like it would park the head just < then 1 second heh but on drives that it works like the blue drives that I am talking about, what does it matter? If I need the head never to park, what is wrong with that?
