The system cannot find the file specify

Hi!

I need a little help. I have a WD my book live (personal cloud plugged on router) and managed to delete a folder full of my kids photos on it.

I got it apart and connected via a SATA to UBS docking station to my Windows 8 laptop.

First the laptop wants me to format the drive, which I refuse to do since I don't want to loose any data.

Recuva found 146 files after a deep scan, but when I click "recover" it sends a message that it can not recover the files even though it found them and shown green and healhy.

Help!!! Am I doing something wrong?? Or is recuva not working as intended?post-70414-0-79794200-1410118696_thumb.png

Recuva does not support any file systems apart from those used by Windows. Ext4 is a Linux file system. Whether this is the problem I don't know, as I'm no ext4 expert.
