Will not mount ext hard drive

[afattitude]

Error mounting: mount exited with exit code 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error
Failed to read of MFT, mft=6 count=1 br=-1: Input/output error
Failed to open inode FILE_Bitmap: 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.

What should I do?

Hi and Welcome !

Post the output of fdisk -l command here. Make sure External hard disk must be plugged in while execute fdisk command.

sudo fdisk -l

* Its small L in fdisk -l.

The error message in your original post has a reference to sdc1 as well as ntfs filesystem. Your fdisk output shows only 1 320GB drive with no ntfs partitions. Did you have your external drive attached when you ran the command as isntructed by devils casper?

i have it attached

shows the message and when i close out the message it continues to come up again and again about every 15 seconds like it continues to try and mount

If you have Windows available, I'd try the suggestion in the error message:

In the first case run

chkdsk /f

on Windows then reboot into Windows twice.

fdisk -l command doesn't work in loop. Are you executing correct command?

sudo fdisk -l

[afattitude]

I'm not saying the command is running in a loop i am just saying that it continues to come up with the error message on the screen not in the terminal.

Since you have posted this thread under Linux Mint, are we safe in assuming that you have a working installation of Linux Mint? Your fdisk output only shows one hard drive with only Linux partitions. The error message in your first post refers to an ntfs partition on sdc1. What is on sdc (sdc1)? Is that a windows operating system? windows data partition?

Do you have windows installed? Can you boot it to run the command suggested in the error message and by elija above?

run chkdsk /f on Windows
then reboot into Windows twice.

If you can boot windows and have run the command, what was the result? If you haven't run it, why not?

How did you try to mount the partition on the external? What command specifically? Did you try mounting from the GUI?

More details on what you actually have and what you have done and the results of what you have done would be helpful. You're being a little cryptic in your responses.

If you are sure that sdc1 is NTFS Partition then execute this command in Terminal :

mkdir win
sudo mount -t ntfs-3g   /dev/sdc1  win  -o defaults,umask=0,force

Check win folder.
