Okay, I think this is simply got to do with the partition "type". If you run
'fdisk' on the device (i.e. the drive), and choose the 'L' option, you'll get
a list of partition types. 'Linux' partition types are typically type 83,
whereas NTFS partitions are usually type 7.
So if Ubuntu *actually* formatted the partition you asked it to as NTFS, but
simply marked that partition as type 73 ('linux'), then changing the partition
type to type 7 with 'fdisk' might allow Windows to see it and/or use it. This
is an interesting experiment, as I've never actually formatted a partition as
NTFS from Linux and then used it on Windows -- however I suspect it will
probably work.

The easiest way I've found is to mount NTFS partitions using the 'ntfs-3g'
package. i.e. 'sudo mount -t ntfs-3g /dev/sda1' for example, once ntfs-3g is
installed. By default for security reasons you either need to do this as root
or via sudo, but there is a way to allow ntfs-3g to allow mounting as a user,
which I believe involves setting the SUID bit on the ntfs-3g binary.
[I haven't done that, but the documentation explains how to do this.]
Mounting/unmounting is the only operation that requires root by default. Once
the NTFS partition is mounted via ntfs-3g, I've been able to use it like I
would any other disk, as a normal user, without any issues.
I have not lately compared the kernel built-in NTFS support verses the ntfs-3g
support in several years now, so I'm not sure which is better. However IIRC I
think I had permissions problems with the kernel's built-in NTFS support that
I didn't have when using ntfs-3g (with the exception of mounting/unmounting).
