error on mount of usb hdd

I plugged in the external usb hdd, and started my back up (rsync -rvua /home/me /media/usbhdd),
and it was working.  Then, suddenly, I got:


rsync: failed to set times on "/media/Elements/tony/.cache/chromium/Cache/.f_001e65.f0RJmL": Input/output error (5)
rsync: rename "/media/Elements/tony/.cache/chromium/Cache/.f_001e65.f0RJmL" -> "tony/.cache/chromium/Cache/f_001e65": Input/output error (5)

So I killed that process, then removed and re-connected the drive.

Now I get this:

$MFTMirr does not match $MFT (record 0).
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.
