What happend: ============================================ - 05 February. First Setup. After some days disk 3 reported as dead. - Ordered directly a new (5th/reserv) drive to keep the backup alive, while waiting to get the "dead" drive replaced. - Put the fifth drive at bay 3 and everything seemed to work fine. - Two or three weeks later the disk 4 reported as "dead" aswell. I changed it directly with the first drive was replaced by the retrailer. - Five days later the drive 3 was reported as "dead" again. So now i got two "dead" drives and three alive in the NAS. - Three dead from totally six harddrives sounds not good and the customerservice asked me to send both the deadrives AND the NAS back. - Customerservice sending report. Nothing wrong with the "dead" drives. They will replace the NAS and send a new one. - Putting together everything and the customerservice-tested drives are still reported as "dead" meanwhile even another one of rest. - That means the complete backup is lost. And now just a factory reset can help. After reformating every disk in another cabinet. - 05 April. Second setup. One day later the disk in drive 4 is reported as "dead". ============================================
Summary: ============================================ - 5 of 6 disks are reported as dead on two different NAS. - i guess - i spend 40 hours on this topic now. ============================================
- Due to the Green characteristic and being environtment freindly of the drives, the nas treats the disk once it spins down as a dead disk that will cause the nas to resync it once it spins up. - I suggest that you replace all of your drive with this model: ST2000DL003-9VT166 with another one.
Thanks a lot - arjoseph - this sounds like a "good" explanation. But if this is true than i bought 5 2TB harddisks, which i can´t use now? Or a 4bay Ultra NAS which i can´t use?
Why is Netgear keeping this harddrives (ST2000DL003) in their Hardware Compatibility List if the NAS can´t work correctly? http://www.readynas.com/?page_id=82
By the way - other companies with same products acting more transparent in this case - more user-friendly:
"Note5 (WD Caviar Green & Seagate Green) These hard disk drives have passed QNAP lab's initial verification of compatibility. However, because many users have reported unstable experience with these hard disk drives, we do not recommend using these had disk drives with QNAP products. …"

I spoke to a manager at netgear support last week about this issue. There are types of seagates that are on the HCL that are also causing this problem.
The only information i was able to get out of him is that there is a firmware update coming soon that MAY rectify the problem. He didn't know for sure though. Supposedly he's been trying to contact the engineers about this issue, but i haven't heard from him in a week.
I'd just like to add that I have the exact same issue. Mac with OSX Lion & 4 Seagate Barracuda Green (2TB). I kept 3 disks outside of NAS, but after first failure I exchanged the dead disk and put in a replacement plus a fourth disk. Then I had two spares, which have both been used to replace broken ones. To add to that, one of the four disks in the NAS is dead, and I have nothing to replace it with. Just hoping my transfer of files via ftp to 5 external drives will make it in time...
Another thing: I think I've had 10 failed disks in total, where one has been replaced by manufacturer, 2 are just gathering dust on a shelf, 1 is still in the NAS, the remaing 6 disk failures have disappeared after reboot. THis however doesn't fix my current issue. I can also add that I wasn't even home during the last two failure, i.e. no load on the NAS.
This should not be happening, I am seriously upset!! It took me a week to move all the files via ftp to the NAS, now I have to repeat the procedure to put the files back, so I can get a new NAS, or factory reset it or something. And then transfer all the data back to the new NAS, this will take me over 2 weeks!
PS. I can't check the disks with SeaTools because I have Mac, or at least I can't find a way to do this.
Please someone sort this out, or at least give a definite answer to what the problem is, since there is quite a lot of us having this issue now. If the disks aren't compatible, take them off the HCL immediately and inform everyone! Come on! If a software update is on the way, when is it coming? I've seen posts from September saying that, and still no new firmware...
