Unable to read data from external drive

#1 Post by albin » 27 Nov 2015, 14:54

After I've mounted external HDD drive few times I receive window with below message

Code: Select all

Error mounting /dev/sdc1 at /media/rafal/TOSHIBA EXT:
Command-line `mount -t "ntfs" -o 
"uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sdc1" 
"/media/rafal/TOSHIBA EXT"' exited with non-zero exit status 13:
ntfs_mapping_pairs_decompress() failed: Input/output error

Failed to load $MFT: Input/output error
Failed to mount '/dev/sdc1': Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID 
hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. 
The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then 
first activate it and mount a different device under the /dev/mapper/ directory, 
(e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details.
After that I run Windows and I try to execute command chkdsk /f g:, but after this I receive information that Windows cannot do anything because disk is damaged or something like that.

On linux I can read all information from disk but without any data. Please see below:

Code: Select all

Volume is corrupt. You should run chkdsk.

Boot sector
Status: OK

Backup boot sector
Status: OK

Sectors are identical.

A valid NTFS Boot sector must be present in order to access any data; 
even if the partition is not bootable.
after I click to List files

Code: Select all

Can't open filesystem. Filesystem seems damaged.
What can I do more to read data from disk?
