I have used my hard drive for months with three others computers with ubuntu 10.04 and another 12.10 and suddenly it stopped working. It doesn't want to mount and the error message says:
Error mounting: mount exited with exit code 13: $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.
How can I access my hard disk again?
