For me the fix was to ckdisk under Windows Vista. Once I repaired the filesystem the drive mounted cleanly when I rebooted in Ubuntu. A problem is that Ubuntu, and other Linices as well, may not have all the hooks to make the NTFS filesystem happy when something goes wrong.
And I do not have enough info to say what exactly went wrong. All I know is that the filesystem integrety check, is that ckdisk?, under Vista found some lost blocks. Can someone say that Linux has enough to fix NTFS when it breaks, I am running U 8.10, not U 9.10, which I think is the bleeding edge.
