I deleted a whole directory by accident on a ReadyNAS NVX. It's a four disk NAS in RAID-X.
Any suggestions or hopefully, experience in how to get the data back? NAS has been turned off immediately after the error happened.
Clone all the drives first before u attempt to do anything. R-studio is very good data recovery software. If the data is very important, I strongly encourage you send all drives to a professional data recovery company before all chances of recovery are lost.
