This question already has an answer here:
I have a laptop with windows 7. One day i cannot access windows. So I'M trying to use Ubuntu 13.10 live USB ("try only" version) to retrieve important files in the internal hard disk.
when I try to open the internal hard disk it says that:
Unable to access "86Gb Volume" Error mounting /dev/sda2 at /media/ubuntu/34BC6628BC65E538: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=999,gid=999,dmask=0077,fmask=0177" "/dev/sda2" "/media/ubuntu/34BC6628BC65E538"' exited with non-zero exit status 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to read NTFS $Bitmap: 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.
Help me, please
