Disclaimer: I am very new to Linux :)

Anyway, onward:

I have a fresh instance of Ubuntu Server (12.04.1 LTS) running on my network and I want to mount a network drive to the server so I can access the contents. The network drive is a SAMBA compatible drive running Darwin OS.

If I run the following command:

smbclient -L //192.168.0.2 -U myuser

It prompts me for the password and then displays output similar to:

Domain=[SERVER01] OS=[Darwin] Server=[@(#)PROGRAM:smbd  PROJECT:smbx-105.4.0]

Sharename       Type      Comment
---------       ----      -------
Comp Staff's Public Folder Disk
CompRaid03      Disk
Dropbox         Disk
Groups          Disk
IPC$            IPC
Public          Disk
Users           Disk
compstaff       Disk

However, when I try and mount the CompRaid03 share, using this command:

sudo mount -t cifs //192.168.0.2/CompRaid03 /mnt/myshare -o username=myuser

I get the same password prompt, but after putting the correct password in, I received this error:

mount error(22): Invalid argument

dmesg | tail returns:

[23576.037373] CIFS VFS: cifs_mount failed w/return code = -22

I don't understand what is wrong with this command. I've managed to mount a share on my current (Windows 8) machine using basically the same command but with a different IP address and share name (obviously). I've spent a good few hours trying to solve this and got no where. Any help or pointers would be greatly appreciated.

Thanks Steve

EDIT

As suggested I've also trued using "user=" instead of "username=":

sudo mount -t cifs //192.168.0.2/CompRaid03 /mnt/svnrepo -o user=myuser

This results in the same "Invalid argument" error.
