openSuSE 10.3 uses ntfs-3g and Fuse by default for mounting NTFS volumes, but doesn't allow writing access in the standard installation.
To enable writing access to NTFS partitions, execute
as superuser and replace in the entries for the appropriate partitions users,gid=users,fmask=133,dmask=022, by defaults but leave the comma and the entry locale=de_DE.UTF-8 right after the comma (without blank) unless you want all the files with umlauts in their names to be hidden from you :-p.
Actually, the only thing you would need to change is the umask, dmask and fmask option as stated in
here (thanks to my beloved Avocadohead).
