Hi
Thanks - using sudo tee did indeed work - and I can create a subdirectory
with
sudo mkdir /mnt/abcd/foo
Here are the permissions ls -l /mnt gives:
drwxr-xr-x 14 root root 0 May 6 2003 wxyz
drwxr-xr-x 1 root root 0 Jan 1 17:16 abcd
and ls -l /mnt/abcd gives:
drwxr-xr-x 0 root root 0 Dec 27 05:07 2013-14
-rwxr-xr-x 0 root root 104 Jan 1 18:08 fred
-rwxr-xr-x 0 root root 8922 Dec 26 19:15 hello2.odt
drwxr-xr-x 0 root root 0 Oct 17 16:33 lost+found
hello2.odt was created with windows and fred was created with the uname
command above. However despite the mount point using the same user as the
one windows created hello2.odt, Ubuntu cannot do anything without sudo at
the start of the command.
Cheers
Rob

Chris is correct, if you want to write a file as root you should pipe the
output through 'sudo tee'
uname -a | sudo tee /mnt/abcd/xyz
This invokes uname as the normal user, but pipes it to tee which is running
as root, so writes to the file as root (it also prints the output to stdout
as well, so can be redirected further if you wish).
What are the current permissions of the mount and its contents? Can you
write to a sub directory?

uname -a will run as root, the output redirect runs as the invoking user.
Therefore, it sounds like a Linux permissions issue over who owns the
mountpoint. I need to understand this myself - so I'll let you know if I
come up with anything.
Regards,
Chris
