Hi,
during the installation I was able to choose how I wanted the NTFS partitions to be accessible. I guess that I chose "R/W by root, R by ordinary user" or something similar.

I also remember that I saw something about NTFS-3g, which I guess is the new, safer way to write to a NTFS partition.
My current fstab entry for the NTFS partition is
do I only have to change ntfs to ntfs-3g in order for it to be mounted as ntfs-3g? Basic question maybe, but since ntfs-3g is not an ordinary kernel module...

If I use the ntfs-3g tools, should I still load the ntfs module, that is, are they compatible? (Maybe it will be loaded by invoking ntfs-3g, right now the module is included in the static kernel.) The ntfs kernel module only supports overwriting files, not creating new ones.

A few options you may not require, upto you, I just gave whatever I use. For ntfs-3g you need Fuse support in kernel. Change the umask according to your needs.
