I have a 1TB external hard drive that I recently formatted to NTFS. It was mounting on my Ubuntu 11.10 fine until just now. I didn't make any changes to affect my OS or my exhdd.
The error that I get is:
Error mounting: mount exited with exit code 13: $MFTMirr does not match $MFT (record 0). Failed to mount '/dev/sdb2': 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.
I tried installing
ntfsfix but no such package exists anymore.
I have never used this HDD on a windows machine. If I need to use an other machine to do stuff to fix this, I have access to a mac.
This is my sudo fdisk -l output: What in the world is GPT? I didn't do that. It used to be NTFS.
