Inconsistent results mounting usb drive with NTFS-3G

[Slates]

I have two Windows usb drives which I mount with identical entries (save the device and label) in fstab as follows :

LABEL=Drive1 /media/Drive1 ,ntfs-3g permissions,umask=077,dmask=077,fmask=077,uid=1000 ,gid=1000,auto,nobootwait,nofail,bootwait 0 0

One drive mounts as expected, and has the ownership and file permissions set as requested in fstab.

The second drive appears to ignore the security entries and initially reports "Using default user mapping". I can also make chmod changes, which I cannot do with the first drive (and do not expect to as they are determined at mount time).

Even though I do not want windows username mapping (and think Ive said so with the permissions param), I created a UserMapping file and placed it on the second drive. This stops the "default user mapping" message, but changes nothing else.

I cant understand why one drive behaves differently to the other, when they are similar in other respects.

I also cant understand why the second drive does not behave as it should according to fstab.

Can anyone help me out with some wisdom/suggestions please?

If you reboot the system and then try to mount the second drive, what happens then?
