Right now I don't understand:
1. if you want read only access, use read only mount.
2. if you want to write that ntfs you need to use read/write mount and set permissions on file/directory level.
Ah yes, and root is always an exception, and additionally handling access rights on ntfs is a bit difficult because ntfs has a different access structure. Also you can have user mapping in samba.

What I want is users and others to have read only.
And root to have write.
Like the Slackware install says .
If I look at the file and subdirectories on the mounted
NtFS partition the dmask and f mask are working correctly
Problem is the. Mount point /mnt/ntfs-c is getting
It’s permissions changed by being used as a mount point.
That allowed me as a user to drag and drop 100 files and subdirectories
Into the root of my NTFS partition.
Next the partition refused to mount.
Then I deleted all the files and directories using windows
And ran chkdsk to get it back mounting again

that is a different issue. As I described you need to mount the drive in read/write mode and you need to specify access at every directory. The mount point itself will not be sufficient for that.

Guess I disagree
