WD Green Drives no good for QNAP's??

[schumaku]

I purchased two WD15EADS-00P8B0 a couple of months ago for my new TS-419P

The majority of issues are coming from the Deep Error Correction to be adressed enabling TLER to 7 seconds for read and write.

Is the performance problem likely to be resolved by QNAP or is it a case of throw them away and buy new drives ?

Assuming the disks are not that bad and don't have to many issues, with TLER enabled and appropriate IDLE3 settings your disks should work reasonably well. Can't tell you if the diabled NCQ on these drives lead to a major perfromance impact.

Repeating, repeating, repeating...

Hi Kurt

Thanks for the reply. Unfortunately I don't have an external SATA / Windows environment I can put the drives into to modify them. I have a 419P and a couple of laptops, so it doesn't look like I can do anything constructive with them. I will buy some more drives, but not WD!. I am just wary of the compatibility list as this is where I started in the first place. If I could modify TLER from within the QNAP Linux environment that would be worth a try, but it sounds like they have to be inserted into a PC/Windows connected enclosure, and the PC booted into a non-windows, DOS environment in order to make the change.

If I can be sure that what I buy will work, preferably based on user feedback I will go with that. I'll have a good look through the forums and see what recommendations other users have before I spend some more money on disks. The performance symptoms seem to be about 20-30 secs of good response times followed by about 45 seconds or so of no response. Effectively unusable. Any attempt at a sustained copy of 400MB or more results in Windows reporting write errors. Still, the box looks good with a nice blue display...

If you have acquired the disk with the TS, you should be able to swap them for NAS capable units with your dealer.

Afraid to hear that - if the full error recovery designed for desktop drivers (not very smart there IMHO, too), the delay can be easy two or more minutes. As I mentioned - WD Caviar XXX desktop drive users might be happy - as long as no read or write issues occur. Nobody can tell, when these errors come up - either on the first day of operations, or after weeks or months.

This is how these disks have been compliance-tested - with some luck. Do not know of for WD or for QNAP, tough. No doubt WD, does excellent disks, simply this Depth Error Recovery feature not substitutable any longer by TLER makes these disks not feasible for reliable NAS operations.

No eSATA on a notebook, any friendly neighbor or computer shop around the door?

My LCC locks high but i don't hear any HDD noise and the LED's are not flickering when the NAS is inactive.
I have Updated the Firmware newly but no change, only the CPU Temp increasses about 10C ( About 38C ).

FWIW, I've stopped holding my breath waiting for a fix from QNAP or WD and replaced the WD drives with 2 x Samsung HD154UI Spinpoint F2 (1.5TB) in the TS-219P. All seems to be well now, apart from the two 1TB disks I have spare now...

No way QNAP can't do anything against this WD mis-concept

Good to hear - consider using these as backup devices, best with TLER enabled to avoid any system freezing...

Enjoy,

I have a TS-239 with two Caviar Green WD20EADS drives configured with RAID1. I've been using it for 3 months now with no failures on the drive. I have already transferred close to a TB of data. I'm transferring data on it day and night. At the same time, I'm streaming movies to the PS3, it's my ftp server, web server and blog site. The WD20EADS drives are pretty fast and the TS-239 is a very powerful server. I'm very happy with this purchase.

[Vikash]

Jason, the performance issues are with the WD10 and WD15 drives AFAIK. From the compatibility list:
"Note8
For improved stability, please update your NAS firmware to v3.1.2 Build1001 or later. There is known performance issue with WD15EADS-00P8B0 and WD10EADS-00P8B0. These two HDDs are not suggested to use with QNAP NAS."

FWIW, I've stopped holding my breath waiting for a fix from QNAP...

I agree it's not QNAP's problem, nor WD's some might argue. But as a consumer and someone who wasn't aware of any incompatibility issues when purchasing the drives, I'm just a bit peeved that I'm footing the bill for what seems to be no-one's error.

Ok, rant over, it's all working now anyway

[Ibbz]

Feasible, but this will take far too much time always resync the RAID with every HDD. Instead of doing one by one, mark the drives according to the slots, shutdown the Turbo NAS, and enable TLER on a standalone PC in MS-DOS boot. Ensure you do not mix-up the drive sequence - then you plug them back to the NAS and boot it again.

Just use the WDTLERS.EXE and WDIDLE3.EXE - do not play around with any other utilities, e.g. fdisk.

Thanks for your help, performed the changes and everything seemed to go fine. Still seem to be running into issues copying large file across in Vista SP1 - but I think that maybe SAMBA related as when I upload through the web file manager, I get constant speed without any issues.

Thanks again.

Hi there,

Due to this thread, I am planning to replace one of the two WD10EADS-00L5B1 with a Samsung HD103SI in my TS-219P with RAID1-setup. Although both WD10EADS drives are in good condition at the moment, I thought, I'd better have a mixed drive RAID1-setup. The Samsung has the same size, cache size and rpm. In this respect, I have a few questions, because I cannot seem to find a thread discussing it:

1.) Is it actually possible what I want to do? If yes, I do not know how to do this without losing my data on the disk I will leave inside my TS-219P.
2.) In oher words, when I shutdown my TS-219P and replace one WD10EADS with the new and empty Samsung, Is it correct that I won't loose my data on the WD10EADS I leave inside the TS-219P, after turning on my Qnap again? I assume, the TS-219P will only format the new Samsung and it will make an exact copy of what is on the WD10EADS (read: mirror it) to my new Samsung. Is this correct?

I appriciate any help. Many thanks in advance.

Ciao!

On my TS-439 Pro I use Seagate 1TB LP drives (Low Power Series)
BUT

I got 4 x WD15EADS-00P8B0 all manufactured from Malaysia
for my HP Mediasmart EX495
1 x WD15EADS-00P8B0 Manufacturer Date Nov. 2009
3 x WD15EADS-00P8B0 Manufacturer Date Oct. 2009

I used the Nov. 2009 one as the main WHS drive
and on it the Load_Cycle_Count only change by 1 when I turn off the EX495 and turn on. ( right now 57 hours on and LCC is only 64)
but for the other 3 drive the Load_Cycle_Count changes like crazy
36hour on LCC 510
36hour on LCC 400
36hour on LCC 413

So I just used wdidle3.exe and disabled the head park on the 3 x WD15EADS-00P8B0 with LCC going up non stop. So now the LCC on them only changes by 1 when I turn off and turn on my EX495

all 4 x WD15EADS-00P8B0 had the head park set to 8000 millisecond by default from WD
I don't know why the one manufacture from Nov. 2009 wasn't giving me high LCC.

are the 3 x WD15EADS-00P8B0 from Oct. 2009 defective????
or the one from Nov.2009 head park is not working properly??

should I get the 3 x WD15EADS-00P8B0 from Oct. 2009 exchanged to Nov. 2009 or just leave it with head park disable?

Hi falofolio,
Yes, simply remove HDD2 form your TS-219P. and then insert your new Samsung HDD (same capacity) to start the RAID rebuild.

Hi QNAPJason

First of all, thanks for your quick response.

Yes, simply remove HDD2 form your TS-219P.

1.) A bit of a stupid question, but if I stand in front of my QNAP which drive is HDD2? The right or the left one? Or it does not matter which one I remove?

and then insert your new Samsung HDD (same capacity) to start the RAID rebuild.

2.) To be really sure, "start the RAID rebuild" means that my TS-219P will not erase my data on the WD10EADS (HDD1), which I will leave inside my QNAP?

Ciao!

[QNAPJason]

Hi falofolio,
Since you have RAID 1 setup, it does not matter which HDD you remove.
The remaining HDD still retains the data and will replicate/synchronize data to your newly inserted Samsung HDD.

I have 2 WD10EADs in a TS509 (along with a couple of RE2s and a Samsung). I have been reading up on the TLER issue and not sure what I should do either. I just bought a pair of RE3's to replace the WD10EADs but am worried that if I pop one out to rebuild it could cause major issues if the other one decides to go offline during the rebuild. Does the TLER fix still work on WD10EADs? I bought the drives back in November but have read it no longer works on newer drives. Anyone have advice on what I should do?
