I noticed that NetGear has announced that they will support the 4K drives (it "will be ready when it is ready"), and that Drobo and Synology already supports them. It definitely sounds like it is a firmware update. While I don't expect a solution tomorrow, I would hope that D-Link is working on this problem now.

So had I...

In the first post D-link Multimedia states that the issue in standard mode is fixable. The real problem comes when using RAID.
Should we expect that issue (at least) for standard configuration fixed on upcoming firmware??

I just bought two 2TB EARS and didn't notice about this...


thank you..

Sorry for asking again but I don't think my question was answered.

If I use the WD20EARS drives in standard mode NOT Raid 1 mode will I have problems

I can see that plenty of people are having problems with Raiding these drives but I don't want to Raid them.

R.

If anyone can answer this that would be great.

I am also just running one WD20EARS drive in standard mode (obviously) and in the future will get another 2TB drive. If I jsut run 2 of them in standard mode (not concerned for mirroring in raid 1). Will I still see a decrease in performance.

Also is it an option to get a WD20EAD drive and use them together? Or does that cause even more problems?

Thanks

The EARS are 4k drives, so  I don't think RAID1 or standard disks makes any difference. In the end, the issue is that the DNS has trouble with 4k aligned drives.

Alright, well luckily I just bought the drive on saturday and can return it no problem. Gotta go online to get some of those EADS. Thanks for the response!

Dear D-Link:

Read before you buy?  Are you kidding?

So can I print this thread and take it to my retailer indicating that *they* should have known about this when they sold me the NAS and drives together, so they should take back *four* unsealed WD10EARS drives?  I'm sure that will fly.

I do not rant online, but I will make a special exception this time.

Anyone looking for WD20EADS and only seeing WD20EARS now widely available might read that the "retail box" version of that drive (sold as WD20000CSRTL) is the same device. My experience this week is otherwise. I have had DNS-323 for a couple of years with Seagate (7200.10) 320's inside. Time to expand; need more space. Have read terrible things about Seagates (7200.11 and .12) so don't want to buy those now. Could not find WD20EADS, which is what I wanted since it is on the "tested" list for DNS-323. Found the WD20000CSRTL at local big retailer; read online that this is same drive. Bought two at the store, and luckily opened the boxes while standing in front of service tech. Found one drive was EADS and the other drive was EARS. Explained my restriction to have only the EADS. Found one more box on the shelf and to my great surprise it was EADS inside the box; the technician conceded they were having quite a few complaints about the EARS drives and seemed to understand my concern for getting two of the EADS. So, look carefully before you buy...including opening the box!

@dpolmann - This exact situation happened to me. Bought two WD20000CSTRLs at Best Buy and ended up getting one WD20EADS and one WD20EARS drive. I'm going to try to exchange the EARS for an EADS and explain my situation similarly to what you described above. Since the actual HDD model number is only on the drive itself, hopefully the BB people will be sympathetic to my situation.

Hello,

I have bought DNS-323 with 2x2TB EARS drives.
I plan to use it in standard form (no raid) with some folders synchronizing between HDD's.
So far, so good.
If anyone of you encounter problems please respond, I will do that also.
I am in no position of returning the drives :-/

[InBonobo]

@DAFILKOV01
Problems will start appearing later on, not right off the bat. By that time, you will have data you will need to move, making fixing it more difficult. I strongly suggest you format properly in the beginning, before reaching that point.

Timezlicer, dcmwai and myself wrote guides on formatting properly. Mine is here: http://www.consumedconsumer.org/2010/06/upgrading-my-dns-323-to-2-x-2-tb-ii_08.html

[DAFILKOV01]

Thank you InBonobo!!!
I have already done it with your recipe...

[HungryBUTTON]

4K drives are not your only problem.

All the new consumer WD drives (Green, Blue, Black) have TLER disabled

Time Limited Error Recovery is required to be enabled on RAID drives.

When data is written or read from a bad sector, the HDD will try to automatically recover this error but this can stall all commands to the disk for up to 2 minutes.

With most RAID's this will cause problems as the controllers (or software RAID) think the HDD is dead so it will drop it from the array.

When TLER is enabled it limits the HDD's error recovery attempt to 7 seconds, after this then the controller will mark the sector as bad, reallocate it then attempt to rebuild the data on the new sector.

Seagate and Samsung also have this problem.

Seagate = ERC
Samsung = CCTL

[jamieburchell]

How would one toggle this feature? Can Dlink confirm this is also a potential issue? Are you saying that enabling the time limit will avoid the issue? If a sector on a drive is bad and results in data loss presumably the RAID is then degraded? Or do the drives generally mark a sector as bad before data loss occurs?

[HungryBUTTON]

That is the problem with the new WD drives, you cannot turn on the feature. WD disabled this ability.

Samsung and Seagate you can enable this feature however it does not survive a power down of the drive. EG. It reverts back to disabled.

In a single disk / non raided scenario the disk will mark it as a bad sector and the data in that sector will be lost unless the HDD is able to recover it within 2 minutes.

In a RAID scenario with TLER enabled the sector will be marked as bad and it will be up to the RAID array / controller to recover the data not the hdd.

In a RAID scenario with TLER disabled the drive will hang and the RAID controller will drop the drive and the array will become degraded

[jamieburchell]

I read that smartctl may be able to read/write this value? I assume the manufacturers will be pushing enterprise level drives designed for RAID but what I don't know is how obvious it will be which drives have this disabled and which don't

http://www.ebuyer.com/product/146077

Looks like WD have RAID specific drives- this one actually mentions this error recovery setting in the spec. Same for the more expensive Seagate NS.2:

Well, I think D-Link does deserve some of the bad blood being spilled here.

I did check the website (not this forum) for compatible drives, and while these particular models are not listed as compatible there is no mention of them being severely incompatible.

It makes one believe that other drives may work, but are not officially tested and approved.
Also many of the drives listed are not available as new purchases, perhaps some newer info could be posted.

An example, I wanted 2 - 1 Tb seatgate drives, but the only ones I can find right now are Seagate Barracuda 7200.12  1TB Sata Drives, the list only goes to 7200.10.

I think D-Link should at least provide a link to the compatibility list on the outside of their packaging. Spending a few dollars to do this, will more than pay off in customer satisfaction.

All this being said, I guess even at D-Link its "Buyer Beware"
