RN104 Raid-X disk 3 failed and disk 2 unknown. Please help
Hi All,
I'm new here but would greatly appreciate a solution to this mess.
I have a fully populated RN104 which has 4x ST4000VN000 drives. It was configured with RAID-X in 2015. The firmware is ...
Hi AlecSmith
Welcome to the Community!
Your NAS had multiple disk failure that is why your volume got inactive. Disk 3 failed and since Disk 2 had an increasing error count it might have failed during that time as well. It's unfortunate that we weren't able to replace the disk at the time of failure.
The best thing is to contact Support and purchase the Data Recovery service or if you plan on DIY, checking on ReCLAIMe might be a good idea. There are other applications used by the Community members that might be advised as well.
I hope you can still recover most of the Data on the NAS. If it's a backup storage then original data should still be safe.
Hope this helps!

Hi All,
Just a post-solution note.
I used ReclaiMe RAID recovery and ReclaiMe data recovery in sequence to recover 4.5 TB of files. This would NOT normally have worked the case of two failed disks. However, one of the disks (they were ST4000NV000 units) was operating intermittently on a USB connection so actually only one disk was fully unreadable. It was necessary to repeatedly close a ReclaiMe dialogue box to continue with the recovery. I automated this using a tool called ClickOff. (It would have been nice if ReclaiMe had offered a retry next time option.) If I had not done this, the process would have taken much more that the eight days it did. I also disabled Windows Update to avoid being restarted by Microsoft.
