2 Dead Disks in two days
I have a ReadyNas Pro 4 running RAIDiator 4.2.19. I have 3x2TB in XRAID2. Disks are Seagate ST2000DL003-9VT166 1863 GB.
I was backing up some things from my MacBook to the ReadyNAS wirelessly last night. The backup was proceeding very slowly, and I got an alert that a disk failed (disk 3). I came home, replaced the dead disk with a backup of the same item. Through Frontview, I rebooted and let the volume resync overnight.
After the sync completed, I took a look at the SMART+ data for the new array. Nothing looked out of ordinary for my novice eyes. I will post the SMART+ data for disk 2 below.
Today, I was attempting to copy the same data to the ReadyNAS. Again, it was going very slowly, and I got a alert that a disk failed. This time, disk 1 had failed.
This seems a bit strange to me. Could the dead disks possibly be caused by the data I was trying to copy? I don't think that could be, but I'm not an expert. The disks are about 3 months old. I have a ReadyNAS NV+ that has had the same disks since 2007, and I've had absolutely no problems with that. Granted, those disks are smaller (500GB).
Is there any way I can check to see if the hard drives are really dead? Could the ReadyNAS somehow be confused? Unfortunately, I don't have an enclosure to test the drives via USB.
Any thoughts or suggestions would be much appreciated.
Thank you for your time!

- Connect the drives to an internal SATA port in your PC and run SeaTools. Run both short and long tests.
- I don't have a PC either, so I ordered an external enclosure. I'll run the tests and report back--most likely in about two days.
Thanks! - So, I ran both tests on disk 1.
Short - pass.
Long Generic - pass.
Why is my ReadyNAS telling me the disk is dead?
Is there something wrong with my ReadyNAS?
I will run the tests on disk 3 now. - By the way, firmware of the Seagate Drive is CC32.
I'm baffled. - If you have ssh access, then /var/log/messages may have something interesting for the time period the drive was kicked out.
steve - Steve, thanks for the reply. I do not have root access. If I am correct, I would need to install an addon (http://www.readynas.com/?p=4203) to enable root access. My concern with installing this addon is that it says Netgear may deny support if it is installed.
Any other thoughts?
Could I get the same information from downloading the logs in Frontview?
Thanks! - jaimeharris, allow me to provide some insight on your situation. We recommend you do not enable root access as any damage to the software of the unit via SSH can cause the unit to not be supported. However, a large amount of the information that would be needed can be downloaded from the logs in Frontview. If you have not already, please contact Netgear support, as we will need to review the logs.
- I downloaded the logs in Frontview and contacted Netgear support. I was surprised at how quick the initial response was.
After review of the logs, support determined that my hardware has failed. They are issuing an RMA, and I expect an email detailing the process tomorrow.
Upon receiving the replacement, I will update the forum about my experience with the warranty/RMA process.
Thanks to all those who have replied to my issue. - Thank you for the update. Hopefully that will cure all.
- I received the email outlining the RMA process. I must say that I am not pleased that I have to pay shipping charges to return the unit. It is still under warranty, and it's through no fault of my own that the unit malfunctioned.
I opted for the Advanced Ground option, which means that I pay $19 to get the replacement unit with a prepaid return label. I've had several experiences with Apple and their warranty program, and they have never, ever charged me shipping, and they have always used overnight service. Since the unit is still under warranty and because I did nothing wrong, I feel that Netgear should pick up the tab.
