Well i see, it is not easy mounting drives:-)

I believe, he wants to mount c:\progs under his home dir.
So he has to write:
not: > >>mount c:/progs /progs
but:
mount [-b] [-s] [-f] c:/progs /home/davis/progs

But this all is not the explanation, why he got an error of mount, 
because he should also be able to mount c:\progs to /progs, why not?

It looks like this, if the mount already exists:
$ mount e:/ftproot /ftproot
mount: /ftproot: Device or resource busy

And it looks like this, if the dir does not exist where you want to be 
the mount point:
$ mount a:/ /hdd/x
mount: warning - /hdd/x does not exist.

And it looks like this, if...???:
> >>mount c:/progs /progs
> >>mount: progs: Invalid argument

I got the same error as i tried:
mount d:\ftproot /ftproot
which normally displays the help!
