May 30, 20179 yr Author After changing the RAID card, the USB drive and keeping fingers crossed, I was able to get the server to boot! It immediately showed DISK1 as unmountable upon boot, so I set it to format and mount. After mounting, I clicked on parity check to rebuild it. But all the data on DISK1 seems to be lost!!!! I can barely hold back the man tears. There used to be 500-600 GB on this disk which is lost. I have attached a picture of the same. IS THERE ANY WAY TO GET IT BACK I have set the parity check again and selected write corrections to parity. WHAT CAN I DO TO FIX THIS???

This is where you went wrong, format in unRAID does the same as in any other OS, it writes an empty file system and parity is updated, rebuilding won't help. 21 minutes ago, apurvasukant said: IS THERE ANY WAY TO GET IT BACK Only chance is using a xfs compatible file recovery software, like this one: http://www.ufsexplorer.com/ I believe there's a trial.

I am downloading the trial right now to see what can be recovered. There is a list of .rec files in the UNRAID flash root (attached pic), can they be helpful in recovery? I also found ReclaMe which does XFS+RAID recovery (http://www.reclaime.com/library/xfs-recovery.aspx) will it be suitable for my need?

No, these are lost fragments from the checkdisking the flash drive. 53 minutes ago, apurvasukant said: I also found ReclaMe which does XFS+RAID recovery (http://www.reclaime.com/library/xfs-recovery.aspx) will it be suitable for my need? Possibly, don't know it, also never used the other one, only known it from other users on the forum, you can try both.

Will post an update if any progress is made. I am assuming that the recovery process will be: 1. Detach the HD from UNRAID and plug into windows system. 2. Run software to recover data from drive and copy to windows. 3. Copy the data back to the drive. 4. Detach HD from windows and plug into UNRAID 5. Parity sync with write changes to disk Would this do the job? Edited May 31, 20179 yr by apurvasukant

Note also that the main thing with data recovery is that you can't do any writes to the disk you're trying to recover from, so for example if the recovery program doesn't work well you can try a different one.
June 13, 20179 yr Author Using UFS Explorer, the scan on the disk returned results in a tree view, arranged by filetypes. I am exporting the entire 'InteliRAW' tree to an external NTFS HDD. I will then use an Ubuntu virtual machine to copy files from the NTFS HDD to the original Segate internal HDD formatted in XFS. Does this make sense? One minor problem with this recovery is that I have lost the directory structure, and will have to recreate the structure and manually place these files there?
