WD RED Drives (WD10EFRX WD20EFRX WD30EFRX)

[schumaku]

G'day,
The WDBMMA0020HNC is colour retail box packaging - Dr. Google is your friend.

Watch your step if the HDD are sold on a much to low price - there are some WDC manufactured mass OEM units in the Internet market with invalid serial numbers - virtually no warranty, lower performance, ... re-labeled by suspect criminals.

So check warranty on the WDC site for the HDD you get.

Regards,
-Kurt.

Hi. I have my TVS-863 running for a month now.
7 drives in raid 6 with drive 8 as hot spare.
The disks are 8 WD30EFRX-68EUZN0 with Firmware 82.80A82. Does anyone know if this model suffers from the LCC bug?

ATM i have load cycles about double the power on hours on all drives. STS about 2 load cycles per hour average. Sounds ok to me.

What recently came up is that one drive [bay 2]
Constantly hangs in smart test at 90% until i stop the test manually.

Smart shows status good, but reports some pending sectors. Which i don't now if they are reported correctly cause the test always hangs.

I started a scan for bad sectors a few hours ago.
Will post the results tomorrow.

What could cause the smart test to hang?
How should i deal with that drive?
Any suggestions?

LCC is not a bug - it's just a counter. The HDD does not stop or fail even if the LCC goes through the roof.

I don't think so - challenge WDC support FMI, we are not the HDD makers.

Anything obvious (or not so obvious) in the HDD2 SMART attributes?

You might consider
- to trigger a full SMART test, and
- to run the WDC Data Lifeguard on the HDD
on a different host than the NAS.

my 3TB WD RED's have ~2x LCC of POH as well, so I guess it's normal (I did not modify any settings of the drives before I put them in the NAS)

[P3R]

My two disks with the same firmware show much less LCCs than you two have:
Poh 8953, LCC 3082
Poh 8843, LCC 3042

Disks from reseller directly into the NAS here as well.

I wouldn't worry about your numbers either. You'll need to have 34 years of power on out of your disks before the LCC should reach the specified 600 k threshold...

Look at the WD web pages yourself:

http://store.wdc.com/store/wdus/en_US/D ... 00/Network
https://www.cdw.com/shop/products/Weste ... 64463.aspx

Both are NAS drives, though I've never heard of the model number you were quoted. I've never seen it mentioned here. The specs are about the same, but the rotational speed is some goofy WD term. So, I have no idea what it is.

The WD20EFRX drives are even cheaper. Plus one year longer warranty. IMHO, get the WD20EFRX on line.

I personally could not use them as they claim the drives are for NAS boxes having 5, or less, bays. I have 8 bays.

I would think a head parking timer factory setting of 8s IS a Bug!
ESPECIALLY for NAS rated drives.

The HDD does not stop or fail even if the LCC goes through the roof.

If so, why would the manufacturers rate a maximum guaranteed LCC count?

[P3R]

The specs are about the same, but the rotational speed is some goofy WD term.

Intellipower is WD marketing language to make slower rotational speed appear more advanced than what it is, slow rotational speed. In reality it's 5400 rpm as it always been on the WD low power lines (Red Pro is different, they're 7200 rpm).

So, I have no idea what it is.

It was already answered by schumaku, WDBMMA0020HNC is the retail package of WD Red.

Old marketing data. When WD Red was introduced, they were said to only work in up to 5-disk NASes. Then it became a huge sales success and Seagate offered competition and suddenly the same disks that previously would fail in an 8-bay chassis would magically work in that same configuration. That's how marketing works...

Not really. AFAIK the change in "supported drive bays" went up with the delivery of NasWare 3.0.
Possibly they tweaked the vibration settings in the firmware there. (feel free to correct me if wrong)

Here are the smart values of my first 2 drives.
(the #2 is the one with the warning)

Drive 1 (Status all good) Drive 2 (status warning only on Pending sectors)

200,Multi_Zone_Error_Rate,100,253,0,0,0 200,Multi_Zone_Error_Rate,100,253,0,0,0

Only real difference is the Raw_Read_Error_Rate (which does NOT increase)
and the Current_Pending_Sector (which does not change at all)

I will run a Full smart test to see if that completes, but i'm in doubt of that.
Afterwards i'll try the WD tool to see if that makes any difference.

thanks,

Christian

AFAIK the change in "supported drive bays" went up with the delivery of NasWare 3.0.

Correct. Of course they had to have a way to distuingish supported from unsupported. At the same time they could relaunch the product and get much more nice free press coverage.

Possibly they tweaked the vibration settings in the firmware there.

Believe that if you want. I don't.

Reds have no sophisticated vibration control. I wouldn't be surprised if "3D Active Balance Plus" is in desktop disks also, only not marketed as such.

I will run a Full smart test to see if that completes, but i'm in doubt of that.

If it doesn't and/or if the WD diag shows problems, that's great. Then you have a case to claim a warranty replacement regardless if the pending sectors can be reallocated or turns out to be uncorrectable. As far as I understand, all NasWare 3.0. disks should still be under warranty for at least another year...

By the way, there is the WD Red SMART load/unload utility to download from WD that checks and fixes the setting if incorrect. Here's how to use it with the disks still in the NAS even.

Thanks. Now I know.

Thanks for the update.

Now I'm Puzzled.

I ran the smart full test on tne NAS Yesterday, didn't complete, hanging at 90%

So i shut the NAS down and ran WD WINDLG on the drive on a separate machine.
Smart status ALL good? No waring on pending sectors ?
Strange.

Currently the full test with WD WINDLG runs. Quite courious what the results will be.

Ok.
Short test with WDDLG fails immediately and Full test also fails reporting bad sectors.

RMA request to reseller is made, new drive ordered.
Hope it survives till the replacement drive arrives, to prevent unnecessary RAID rebuilds.
