WD Green Drives no good for QNAP's??

[petur]

the fix looks to be only for the enterprise drives, not the GP consumer ones (EADS)

Where did you read that? I know somebody planning to use these drives, must know if I should stop him.

I did but I have a drive fail within the first 12 hrs, I pulled the drive, reinserted it, rebooted the NAS and ran some tests on the drive, seems fine now, its rebuilding, otherwise its fine.

I seem to have found the answer to my problem. Unfortunately too late.. I have a TS-209 which I have used with a WDC RE2-GP of 1 TB. Bought it 1,5 year ago and in the beginning it was working a lot with BT but for the last half year it has mainly been runing with more infrequent use. Even so it has been turned on 24/7. Today it broke down so I haven´t got the possibility to check my LCC count, but it doesn´t seem to far fetched that it is caused by the issue mentioned here. Just to let you know my experience.

Hello,

did you noticed that the new firmware 3.1.2 Build1014 from the 2009/10/23 got something for the WD drives ?

[Enhancement]
- Disable NCQ to improve the RAID stability with some Western Digital hard drives (WD20EADS, WD15EADS, WD10EADS, WD2002FYPS, WD1002FBYS)

All the WD 2TO owners, can you try it? Do you see any differences ? I'm particularly interested by 4x WD15EADS drives..

Thanks you!

I recently purchased a WD20EADS-00R6B drive for use in a NAS to be determined. I'm wondering how this could be a real problem when Western Digital puts these same drives in their ShareSpace models?

Peter, just read this. Sorry I think I misunderstood the orignal post. WD have released firmware for the enterprise green drives which overcomes this issue allowing the idle time to be configured. However WD haven't released a firmware update for the consumer drives, and the enterprise firmware can't be used on consumer drives.

I think though what the poster & you were refering to was a QNAP firmware to work around the issue. I have no idea whether the QNAP firmware applies to both sorts of green drives.

Apologies for the confusion

Unfortunately I'm running 3 (that's right, 3) of these drives in my TS-409 Pro... Unfortunately I wasn't aware of this issue before settling for the WD drives...

My 3 drives give the following SMART readouts:

193 Load_Cycle_Count 140 140 000 180598 OK (WD10EACS)
193 Load_Cycle_Count 141 141 000 179235 OK (WD10EACS)
193 Load_Cycle_Count 183 183 000 53971 OK (WD10EADS)

Are these levels high enough to warrant replacing the drives immediately? Obviously I'll have to replace them eventually but I'm just wondering whether these numbers indicate the drives are on the verge of imminent failure, or if I have some time up my sleeve...

Mine are about 2 years old now and are at 330k so you have headroom for sure

I have a ts-439 in combination with 3 WD20EADS. The new firmware didn't fix it for me. The disks still park the head every 20 seconds or so.

The new firmware is not supposed to fix that! The new QNAP firmware disables native command queueing (NCQ, try Wikipedia), which is a totally different issue and, as the firmware release notes say, affect RAID stability, which it certainly does for me.

Also, the consensus seems to be that the head parking frequency can only be fixed by updating the harddisk's firmware. Hence this is beyond QNAP's control, but must be done by the manufacturer Western Digital, who seems unwilling. It appears from responses by Western Digital Support Service that their stance is that the green drives are for private home users only, and Western Digital defines NAS outside the activities permitted for private home users (except for the their own NAS product line, of course).

I was aware of that, but I was answering the question in context Anyway, the issue still persists. My TS-439 has 3 WD20EADS. 1 is a WDC WD20EADS-00R6B0 01.0, which has an LCC of 8, while the other 2 are of type WDC WD20EADS-00S2B0 04.0, which both have an LCC of 3615. All disks were inserted at the same time and have a Power_On_Hours of 39.

Currently, I'm keeping the disks alive by touching a file every 5 seconds

Hi,

We were talking about WD15EADS, version WDC WD15EADS-00P8B0 01.0 in this post :
http://forum.qnap.com/viewtopic.php?f=25&t=21296

And unless someone find a solution, this drive is clearly not usable on a Qnap TS at least on 439,509,639 and 809.
Whatever tried, different release, adjusting tler and lcc, the raid is not stable, and does not sustain high activity, which lead to intermittent stall.

We would love an answer from Qnap about the fact that this drive is in the compatibility list

Hi Guys,

Don't want to confuse the issue, but I have a QNAP-639 with WD Green 1TB drives (6) and this is the hard disk information and SMART info for 1 drive (which is consistent for all 6).

Hard disk model Western Digital Caviar Green family
Model number WDC WD10EACS-00D6B0
Serial number WD-WCAU42825520
Disk capacity 931.51 GB
Firmware version 01.01A01

ID Description Value Worst Value Threshold Raw value Status
1 Raw_Read_Error_Rate 200 200 051 0 OK
3 Spin_Up_Time 162 162 021 6875 OK
4 Start_Stop_Count 100 100 000 14 OK
5 Reallocated_Sector_Ct 200 200 140 0 OK
7 Seek_Error_Rate 200 200 051 0 OK
9 Power_On_Hours 092 092 000 6089 OK
10 Spin_Retry_Count 100 253 051 0 OK
11 Calibration_Retry_Count 100 253 051 0 OK
12 Power_Cycle_Count 100 100 000 13 OK
192 Power-Off_Retract_Count 200 200 000 1 OK
193 Load_Cycle_Count 200 200 000 14 OK
194 Temperature_Celsius 118 108 000 32 OK
196 Reallocated_Event_Count 200 200 000 0 OK
197 Current_Pending_Sector 200 200 000 0 OK
198 Offline_Uncorrectable 100 253 000 0 OK
199 UDMA_CRC_Error_Count 200 200 000 0 OK
200 Multi_Zone_Error_Rate 100 253 051 0 OK

So for some reason I am not suffering from the same parking problem. And I'm running Firmware Version 3.1.1 build 0815T.

hi,

I'm proud owner of a TS110 Qnap NAS, but got one LCC problem with it!

My HD specs:
Family : Western Digital Caviar Green family
model : WDC WD10EADS-00P8B0
firmware : 01.00A01

my S.M.A.R.T. specs:

Power_On_Hours 85
Power_Cycle_Count 17
Load_Cycle_Count 5389


My Load Cycle Count is very fast rising. Is there already an solutions for this problem?

I've seen Synology got a fix for the Dutch customers

Just tinker with the link and tadaaa, it's in english. Anyway, I'm solely running Mac, so I have to find one who will sacrifice their pc in order for me to try this.
