Western Digital WD20EADS 2TB Compatability

[BigBearf]

I have been running WD20EADS drives for 8 months with no problems with the following suggestions.
See my sig below, the older firmware drives have been running without any alterations and have shown no problems. The last 2 drives that I got about 4 weeks ago required WDidle3 and WDTLER fixes and have performed flawlessly since then.

I got mine from BestBuy and checked the firmware and made sure that I could use the above fixes on the drives. Note that 2 of 4 drives had been previously used and repacked as new so make sure the drives are new and if possible have the older firmware (see sig below=00R6B0 firmware). You have 30 days to exchange the drives if needed. I think that it is worth it to use the WD drives since Seagate has really had some problems in the past 16 months.

I will probably get a know compatible firmware backup WD20EADS and eventually go to Enterprise drives after all of the bugs get worked out.
Hope this helps.

Thanks for the info BigBearf.

I have seen that the WD20EADS 2TB drives have now been added to the official HCL for the pioneer pro which is great as I have been waiting to buy them.

Can any of the Jedis advise if this means that the high LLC count issue with these drives in ReadyNAS units is fixed? No specific firmware release is mentioned as required in the HCL.

I recently bought a WD10EADS for testing in a new RNPP and it has generated 1541 load cycles in 25 operating hours. I am aware that there is a WDIDLE3 fix but that this invalidates the WD warranty. I have had problems trying to apply the fix on the WD10EADS drive. I would like to know if this issue is now resolved with the WD20EADS 2TB drives or if Netgear is unconcerned about the high LLC counts?

I've been running two of these drives on my Pioneer for around 9 months (along with 2 1TB Seagates). I had to RMA one of them early on due to a high reallocated sector count, but I've had no problems with the replacement. I use mine mainly for media streaming.

Here is a screenshot of the SMART status of my RNPP



As you can see I applied the WDIDLE3 and WDTLER dos fixes to the last drives. The first 4 have been OK without the fixes. Go figure.

I've been running 4 x WD20EADS drives (all with the same firmware and model--01.00A01 / 00R6B--in my RPP for about six months and did not apply any of the drive patches suggested. My smart info looks fine, although I am concerned about the Load Cycle Count once I soon stop running Transmission (trying to finish the last torrent downloads). With Transmission running, its probably keeping my drives awake most of the time since its continuously downloading. I have my machine turn off from 2am-9am. The fifth drive I just added a couple of days ago.

Now that the WD20EADS drives are added, is there a minimum Raidiator version or prerequisites to use on the pro pioneer? can you just buy any wd20eads drive and use it--what changed, how is the "fix" or compatibility achieved exactly--what minimum conditions/restrictions allow compatibility or is this newfound compatibility a pig in a poke? Did i/we miss something?

[chal2les]

How does this only apply to the PRO, but not the NVX and downward?

What changed?

Thanks.

I don't know when the list changed, but I'd be on the latest version of RAIDiator x86 just to be safe.

[chal2les]

Can we get an update from the Jedi's.

[dia3olik]

yeah please!
has the load unload issue been solved?
or only the tler one?
thanks!

Why are the LCC so high?? I have the ReadyNAS Pro Business Edition with latest firmware

[OzzyJim]

Hi, just looked through postings from Feb 2009 till Mar 2010!!!!!!!!

Have not seen positive or negative compatibility statement from the Netgear for WD20EADS on ReadyNAS Duo or NV+.

Would be grateful if Netgear (Jedi Council??) would put this to an end with a qualified HCL inclusion or stated exclusion for Duo and NV+.

(This is probably for another thread - as for the qualified WD20EARS inclusion - its great that something has appeared - although I was unable to source HDDs with the firmware / model specified.)

[Jonavin]

Just added a WD20EADS (00S2B0) recently after I saw that it made the HCL list and found that my LCC is extremely high.

Non-Zero SMART stats:
Start Stop Count 5
Power On Hours 371
Power Cycle Count 4
Power-Off Retract Count 3
Load Cycle Count 42257
Temperature Celsius 36

ReadyNAS Pro Pioneer running 4.2.9

[jmirabil]

You guys see why I was so skeptical of this wd20eads inclusion and made the pig in a poke statement now - Netgear HAS NOT solved this compatibility issue and is content to not even answer and clarify such questions publically and authoritatively in a forum like this. Unacceptable.
