On the question how to check and/or fix a broken ntfs filesystem, I am lost.
I missed the original post, but if you want to check the ntfs file system, you need an XP disk. look up CHKDSK.
When you have cloned a dying hard disk with ddrescue (and were able to only copy a fraction of the information) your first choice should not be CHKDSK. CHKDSK primarily tries to restore the filesystem into a consistent state, which means that directories that are only partially readable will be completely lost completely afterwards - not very good if you try to rescue data.
When you have the disk space available, create a clone from the clone and try several tools on it (free and commercial ones). When the data is "important", buying an additional external hard disk may be worth the money (especially since it can be used afterwards, regardless whether the data recovery was successful or not). Give each tool a clean clone after having copied all the data it could rescue.
Note that cloning from a failing drive can take a long time (hours to days), cloning the healthy clone afterwards is much faster.
In the (two) cases where I tried to rescue lost data from a friend's hard disk, the commercial Windows tool "Get Data Back for NTFS" (from Runtime software) was able to rescue most of the files where free alternatives failed. There is also a trial version available that can list you the files it could rescue (and can save a small number of files so that you see it is right).
Of course, it's better to make backups and never need these tools.
