[solved]nie odczytuje dysku zewnętrznego

[pacman401]

dysk zewnętrzny 120GB na usb
pewnego dnia poprostu mój menadżer plików go nie wykrył
przed awarią jedna partycja na cały dysk z systemem plików ext4

fdisk -l /dev/sdb daje taki wynik

Kod: Zaznacz cały

fdisk -l /dev/sdb
Disk /dev/sdb: 120.0 GB, 120034123264 bytes
255 heads, 63 sectors/track, 14593 cylinders, total 234441647 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0d83fb3a

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb2              63   234436544   117218241   83  Linux

jak widać fdisk rozpoznaje wielkość dysku i wielkość i ilość partycji ,tylko nie rodzaj i zawartość
a tak to widzi disk utility


gparted widzi podobnie tylko że na końcu dysku są 2MB wolnego miejsca
teraz jak piszę ten post odpaliłem "attempt data rescue" z menu gparted

podczas podłączania dysku słychać jak go czyta przez dłuższy czas później przestaje

tak samo na innej przejściówce (bo mam drugą) i na innym kablu

pomoc ... ?

=============================edit ok godziny później
"attempt data rescue" zakończyło się niepowodzeniem
