(SOLVED) Just formatted 8TB HDD and lost all data, any chance for data recovery?

[HAMANY]

Hi,

 

I went through the same issue in this post (Disk rebuild lost data), and I did the same mistake. Yes, unfortunately, I formatted the drive when I got the format unsupported message.

 

This is a brief of what happened:

- Disk 1 got disabled while the array is running.

- Restarted the server, didn't see any SMART errors, Disk 1 rebuild started.

- After around 50%, Disk 1 got disabled again, and rebuilding stopped.

- Checked the connections, restarted the server again, no SMART errors.

- When I started the array, the rebuilding didn't start, but I got a message saying that Disk 1 format is not supported and I have to format it.

- I did the format, thinking that the data still will be available through emulation.

- I lost around 7TB of data, Disk 1 is showing 8TB free space

 

Is there any chance for data recovery? I don't have a backup, the only way is to re-download all files again which will take months

 

Please let me know if you require any further information. Your help means a lot to me. 

Much appreciated.

Best option is to use a file recovery tool, UFS explorer has been used with more or less success by others users before in similar situations.

Thanks. Is the Standard edition enough?

Yes, and you can use the trial before buying.

UFS managed to restore around 5.6TB of data, but unfortunately everything is corrupted.

The good thing is that I know what has been deleted and I can re-download them gradually, in addition to the lessons learn.
