"fsck" for ntfs ?

[stan]

I was tying to sue Ubuntu to help a friend recover data from a disk from a
crashed windows machine this weekend. Ultimately, I was unable to do so
because I could not get the ntfs partition on his disk mounted. This appears
to be because the disk had not been "marked clean" when his machine
crashed, or at least that is how I interpreted the error message. Even adding
the "force" option to the ntfs flavor of mount did not work.

Am I interpreting this correctly? If so, is there a tool that can do the
equivalent of fsck for ntfs?
