As you can read in many posts, it's a bad idea to have direct write access to NTFS partitions.
So, the question is, why do you need that? Can't you create a FAT32 for sharing files between Windows & Linux?
Or share files in some other way?
/dev/hda1 /mnt/music ntfs noauto,ro,user=nac,fmask=755 0 0
The "ro" says that you'll mount it for reading only (which is OK for NTFS, but not really what you were looking for).
See man mount
