Since I am dual-booting the laptop between Windows XP and Ubuntu, I would like to access my NTFS partitions in Ubuntu for both read and write. To tell Ubuntu to mount them everytime at boot:
Install the ntfs-config package. It ships with the ntfs-3g driver which has safe write capability for NTFS.
From the terminal invoke:
$ sudo ntfs-config
ntfs-config dialog, choose the NTFS partitions you want mounted at boot and choose Write capability for internal drives.
ntfs-config mounts the partitions immediately and also adds the relevant mount entries to
/etc/fstab so they are also mounted at boot everytime.
