rw access to ntfs

[Ben Paley]

Hello,

I'm running 5.4 on a dual boot machine with winxp. Here's the relevant line 
of /etc/fstab:

/dev/ad0s2              /mnt            ntfs    rw              0       0

It mounts fine with no errors at boot time, but I seem to have read-only 
access.

I've done a bit of googling about this and everything I find which mentions 
this is quite old, and all the replies seem to imply it should have been 
sorted by now.

Any ideas?

Thanks,
Ben
