Bad magic number in super-block while trying to open

Merevlemezek, vezérlők

Film nézés közben, lefagyott a gép. Kikapcsolás közben láttam sok I/O errort.

Innentől kezdve nem látja bootolás folyamán a meghajtót. A régi rendszerem alól ezt látom:

Ja majd el felejtettem , az adatok úgy látom megvannak. Menteni nem kell mert ami fontos volt az mentve volt mindig. Inkább csak a belakott rendszeremet sajnálnám.

Tudnátok segíteni, merre lépjek tovább ? Érdemes ezzel foglalkozni vagy kuka ?
