Yes, most likely.

I disagree at this point in time.

I purchased WD30EZRX WD-GREEN on 8/9/2015 and finally had a chance to use install it this weekend. After 14 hours of running, i only see 4 LCC. Do I still need to use WDIDLE or did WD finally changed them?

You didn't give enough information such as you could have turned the power on and off 4 times which would also increase the head load count to 4. Wait 24 hours and post all of the SMART output and I could give you a better answer. At this rate (assuming it stays constant) you would hit about 158,000 load counts in 3 years.

@alexg I would at least check it and see what it's set at. If it's 8 seconds like most Greens are I'd change it.

I imagine the low LCC is probably due to whatever workload was being used for whatever testing, though a WD Green with reasonable idle timer would be nice.

alexg · Oct 26, 2015

26 hours. Perhaps numbers are low because this drive is in my replicated pool and not my primary. Replication occurs on a nightly basis. But I also ran resilvering in the last 24 hours to replace another drive. Does anyone have a link where I can download wdidle3? All the links to WD sites are no longer get you this utility.

Code:

  9 Power_On_Hours          0x0032   100   100   000    Old_age   Always       -       26
 12 Power_Cycle_Count       0x0032   100   100   000    Old_age   Always       -       2

Download Ultimate Boot CD, it's included in the hard drive utilities.

I agree and I was thinking the same thing, it would be nice to see the default timer changed and maybe it has been, it would be nice to know.

@OP, you sure don't want to post too much SMART data, do you. But if your drive has been constantly busy, your LCC will go up but the question is how fast. Usage is a big factor.

@solarisguy Thanks for reposting those links, I'm sure many others will utilize them in the future.

You do realize I gave you the files as attachments in the original post?....

Heck, that was 11 pages or 208 postings ago. ;)

I did...

However, I did not want to waste time questioning why he wanted WD links and not your attachments...

alexg · Oct 29, 2015

Guys, thanks for the links. I mean no disrespect, but I don't trust attachments someone posts. The LCC counts continue to grow and here is the latest full smart data (yeah, I was just trying to save you guys reading time by posting LCC data only). I will be making WDIDLE3 changes over the weekend.

Yeah you better get after those drives. The LCC in my wdidle'd greens is 162 with 8372 power on hours.

anyview · Nov 12, 2015

Could anyone let me know if I can use wdidle3 for wd green 5tb ? Thanks !

solarisguy · Nov 12, 2015

@anyview, there were no reports that it does not work.

If you do, please share with us the results and the model number of your drive (date it was manufactured would be a nice addition).

I just tried adjusting the time to 300s for my new WD Green 2 Tb WD20EZRX
It works , thank you very much.

@Ali777, when was it made? (The date it was manufactured is on the disk label.)

@solarisguy, although I'm hearing sound like water dropping from the drive
Is that normal ?
I noticed that my other hard drive that I extracted from wd mybook 1TB has the same sound, its kind of annoying sound
My Wd 1TB blue doesn't have these sounds

solarisguy · Dec 8, 2015

@Ali777, is it tap, tap, tap, tap...? All the time?

Did you hear the same sound before using wdidle3 ?!?!?!

yes sounds like tap tap

actually I didn't pay much attention before using it I just checked the S.M.A.R.T it was OK

I tried to set it back to 8s, the sound disappear after the 8s
