I'm unable to mount one of ntfs file system drive since the system got turned of while copying few files to this drive.

I'm getting following message:

Unable to Mount 94 GB File system error mouting: mount exited with exit code13: $MFTMirr does not match $MFT record (record 0)

failed to to mount '/dev/sda6':input/output error

NTFS Either inconsistent or there's a hardware fault, or it is a softraid/fakeraid hardware. in the first case run chkdsk/f on Windows and then reboot into windows twice. the usuage of 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, (eg/dev/mapper//nvidia/eahaabcc1) please see the 'dmraid' documentation for more details

This is a partition of my system hard disk, and I can see the same in Gpartition but I get the same error report there also. I've got 1000s of files in this drive, please let me know the ways to recover/mount this drive safely. I don't have a windows system to do any sort of diagnosis.

Appreciate your help and thanks in advance

NTFS support in Ubuntu is excellent until something goes wrong; because NTFS is basically a Windows filesystem, many of the tools assume a Windows system is available. It may not be possible to fix it without a Windows system to check from, but according to the first answer to this question it's possible to download a Windows recovery CD that would allow running chkdsk.

It is also worth examining the various ntfs tools installed by default, especially ntfsls and ntfscat. These allow one to manually access files without mounting the filesystem, but for thousands of files it's naturally not very practical, and as such should be considered a last resort.

The best solution, in terms of the simplest one with a good chance of success, remains gaining access to a computer with Windows, connecting the hard drive, and running chkdsk /f over the partition in question.
