O tai ką daryt su tuo /dev/sda11p1? Nes reealiai tai tokio failo nėra:

# ls -al /dev/sda11p1
ls: /dev/sda11p1: No such file or directory

# ls -al /dev/sda11*
brw-r----- 1 root disk 8, 11 Feb 11 20:32 /dev/sda11

Šitas http://www.diskinternals.com/linux-recovery/ ties ~80% tampa not 
responding, nors iki lūžimo rodo, kad rado ~20k folderių ir 0.5M failų 
failų. Pasiūlyk kokį nors įrankį :)
