I am having trouble getting write access to my Windows partition, which fails to boot now. I want to try to try some repair techniques but it requires moving files around, which requires write access.

It is an NTFS partition.

On Knoppix, it mounted the device as:

/dev/hda1 on mount point /media/hda1

The first thing I tried doing, is right-clicking the hard disk icon on desktop and chose "change read/write mode". Said yes to the popup and then got the following message: "The remount command failed. Maybe there is another process accessing the filesystem currently".

Then I looked online and found a command I could try on the command line, so I wrote it as this:

mount -t ntfs -o rw /dev/hda1 /media/hda1

And I get the following response:
Failed to mount '/dev/hda1': Operation is not supported
Mount is denied because NTFS is unclean. Choose one of these actions:
...

The first option had something to do with making sure windows shut down cleanly- not sure how it determines that but anyway this is impossible because windows crashed.

The last option was to mount in read-only mode. Not what I want.

So I try the second option which is to run ntfsfix, typing: ntfsfix /dev/hda1
and it just hanging there. unless this is supposed to take a really long time (over 10 minutes now) then I think it's safe to say it ain't working. (though I am still leaving it to hang there, afraid to try and cancel it. hoping by some miracle it will finish)

Any other ideas?
