Good luck with the repair.oh dear - I really am a bit overworked.
atm I am frustrated, though: my library pc crashed (I use it to store my audiobooks etc). I managed to repair all damage to HDD1 which carries the OS (Debian Linux 8) However, HDD2 with all my files on it got dismounted and the computer stubbornly refuses to find it - it doesn't even show uo in the boot menu. It can't have been damaged too badly in the crash so that at least its physical presence should register and it does start - I can feel the vibration. I could repair it if I could mount it but how can I mount an invisible drive? It's utterly frustrating!
