WD Red 3TB failure - JBOD - ReadyNASRND2000v2 #25795764
Do I have a readynas RND2000v2 which was setup with two 3TB Red discs in JBOD mode.
One of the discs doesnt come online.
Placing it in a docking station, you can hear the noise that it makes,...
I see you mentioned in your support case that the disk didn't even show up when you tried using WD Data Lifeguard Diagnostics.
Your logs show the disk as healthy and then some I/O errors start and the disk no longer works.
It looks like your disk failed very badly. Unfortunately when there are physical issues with a disk, data recovery attempts are very expensive. Any data recovery attempt may ultimately be unsuccessful.
You did choose a good disk model the WD RED 3TB WD30EFRX, but unfortunately any disk can fail badly in any system. The only appropriate protection against this is to not store your data on just the one device (i.e. backup your data). Note if the primary copy of your data is on your PC then the copy on the NAS is a backup, but if the primary copy of the data is on the NAS, then the copy on the NAS is not a backup. Backups are particularly important for irreplaceable data such as family photos and videos. I would recommend keeping both on-site and off-site backups.
We do sell data recovery services but only software data based. We don't do physical repairs to disks. Your disks would require physical repairs for a data recovery attempt, you would need to try 3rd party data recovery services (e.g. from the drive manufacturer), should you wish to do so. The attempt may be unsuccessful and if you want an attempt to be made you likely would need to pay regardless of success/failure (this would depend on your agreement with them, but I would assume that they would want you to pay regardless of success/failure). A data recovery company may do a quick analysis and provide you with their opinion on the probablity of succcess before racking up too much time, but it depends on which one you use and what agreement you make with them.
The cost, time and uncertainty when it comes to data recovery are reasons why backups are important. No important data should be stored on just the one device.
With JBOD if a disk fails all the data on that disk may be lost.
Thank you for your reply.
Okay, so as I was operating in JBOD, Drive1 was my C: and Drive2 was my D:
Drive2 (D) is the one that failed.
As Drive1 (C) had the firmware and config/logfiles of the NAS on there, is there a chance that I could find a listing of the files that were on the failed drive, on there? -> This would help me determine what I have lost and how sure I want to pay for professional data recovery.
Thank you.
