Failed Disk ReadyNAS NV+ v2
So I think my naivete may have done myself in but I'll ask for some step by step advice if there's anything I might do to recover from this.
I use a ReadyNAS NV+ v2 with 3 of the 4 bays filled with red WD 3TB drives. Its X-RAID2. Its running 5.3.1. It has a single share. Its storage for a media center whose set up is relatively automated. It has no backup (no chastising please on that point :oops: )
I don't have it set up to email me with warnings but a couple weeks ago I went to play a video stored on it and Plex couldn't find it. So I take a look and since May the NAS has been warning about an impending failure of Disk 2. So I figured that the disk had finally failed and bought another disk, same brand and model. I replaced it and he log read as such:
The ReadyNAS reported the disk as present but the volume light never went to green and the share was unaccessible from any computer.
So here is where I think I may have screwed up. I gave the ReadyNAS 48 hours and when I still couldn't access the share, I rebooted it. The next item in the log (and this is immediately after reboot) is:
Would the log indicate that the disk initially had been processed when I first added it? Should I have avoided rebooting?
Not that this is a matter of life and death (just 1000 movies) but any next steps to save this and properly replace the disk? And failing that any thoughts on what my options in terms of data recovery from a three disk X-RAID2 set up with a single failed disk? Keep in mind you're talking to a relative moron on this subject.

New disk detected. If multiple disks have been added, they will be processed one at a time. Please do not remove any added disk(s) during this time. [Disk 2]

A disk was removed from the ReadyNAS.

Disk removal detected. [Disk 2]

Reallocated sector count has increased in the last day.
Disk 2:
Previous count: 5480
Current count: 6552
The ReadyNAS reported the disk as present but the volume light never went to green and the share was unaccessible from any computer.
So here is where I think I may have screwed up. I gave the ReadyNAS 48 hours and when I still couldn't access the share, I rebooted it. The next item in the log (and this is immediately after reboot) is:
Fri Jul 3 21:40:50 CDT 2015
System is up.
Fri Jul 3 21:40:49 CDT 2015
The paths for the shares listed below could not be found. Typically, this occurs when the ReadyNAS is unable to access the data volume.

Volume scan failed to run properly.

- Check your disks first using disk diagnostic tools from the drive manufacturers (Seatools for Seagate or WD Lifeguard for Western Digital). There is a chance that the other disks also have issues.
- That reallocated sector count is huge. That disk should have been replaced a long time ago when the error count was rising rapidly or about 50. I agree it is possible another disk also has issues.
- So the other disks past muster.
I'm using a cheap external container on my desktop to mount the disks and the other WD red disks mount and run through Lifeguard fine. THe computer doesn't even recognize the failed disk 2 from the ReadyNAS. Literally, nothing appears in explorer or on Lifeguard when I put it into the mount.
Still, the ReadyNAS NV+ v2 has lost its volume and the share with all the media on it is inaccessible even with the replaced disk.
Any advice on recovering data? - You may need to clone the failed disk e.g. using dd_rescue.
When a problem like this happens, rather than trying to fix it yourself if you have no backup you should consider contacting support and purchasing any support contract that is required.
Important data should not be stored on just the one device.
