it shows error like

Error mounting /dev/sdb1 at

Failed to mount '/dev/sdb1': 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.

  • Could you please write what your question is? Is it "how do I mount it on Ubuntu?" or "Why is it not working?" (for which the reason is written there). Does the drive work on other operating systems? – Andrea Lazzarotto May 21 '16 at 21:37

On your external harddrive, the master file table (MFT) and its copy (MFTMirr) are seemingly no longer consistent.

You might want to fix it using the Linux tool ntfsfix on the command line.

Connect the hard drive to your System.Open a terminal by CTRLALT+t. To sum it up Enter

sudo ntfsfix /dev/sdb1

in the terminal and press Enter. You will be asked for your password. Enter that and press Enter again.

and you will be good to go. Hope it helps.

  • AFAIK ntfsfix does not repair inconsistencies between $MFT and $MFTMirr. According to its man page «ntfsfix is NOT a Linux version of chkdsk. It only repairs some fundamental NTFS inconsistencies, resets the NTFS journal file and schedules an NTFS consistency check for the first boot into Windows» – Andrea Lazzarotto May 21 '16 at 21:35
