My hard disk suddenly appears to be inaccessible, with the following error:

Unable to mount external HD

Error mounting: mount exited with exit code 13: $MFT must be non-resident.
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.

The information inside the HD is valuable for me,Any help please?

First, as you said

The information inside the HD is valuable for me

I would suggest to use testdisk utility and attempt to recover your data into a safe place. In future, of course you should make backups of your important data.

Use smartmontools and check the disk's health. If it's ok, you should follow the "error's suggestion" and run the chkdsk command from a Windows PC.

If you don't have Windows available, an alternative method is to use ntfsfix command which is included in ntfs-3g package. From there you can attempt a repair. See an example here.

A way to ensure that your data will be remain intact, does not exist.
