# guestfish -N fs:ntfs -m /dev/sda1 touch /this-is-a-test This will create an empty NTFS filesystem in a disk image (called 'test1.img'), then touch one file. Since it doesn't involve any existing filesystems or guests it's a good test of whether ntfs-3g is working or broken. You can also run: $ strings -e l test1.img to look at strings in the test image.
