Hi Stu,

The volume at media is a Windows based NTFS NAS appliance. It's stored
in another building and we use it to back up to. I'm not too bothered
with the disk usage on that itself, it's more the local drive on the
web server which is making me want to stab my own eyes out at the
mo!!! :-p

Oh, I forgot to mention earlier on, the Ubuntu web server is a virtual
server running on VMware. I don't suppose that should make any real
difference though....

I'd have thought du would show the file if it was just hidden though
wouldn't it ?
