Vracanje obrisanih particija

[Cobe]

Nekako sam uspeo preko fdiska da obrisem sve linux particije sa oba hard diska osim jedne koju sam trenutak pre toga napravio od ntfs particije. Pokusavao sam da obrisem particiju sdb6 koja je bila extended i nije mogla da se koristi iz nepoznatih razloga, posle restarta nestao je BT5r3.
Instalirao sam watOS da bi se obratio za pomoc, evo sta kaze fdisk -l:

Da li postoji nacin da vratim hard diskove u proslo stanje?
Hvala unapred.
