OS X :: Trying To Move Documents Folder Via Symbolic Link / Not Working

I've just recently received my new iMac 27" i7 and have the SSD + HDD option, where the SSD contains OS + Applications and the HDD contains data. I read that moving the whole Home folder was not a good idea, therefore, I wanted to just move my Documents, Pictures and Download folder to the second internal HDD. I read an article/tutorial how to do this and this is what I followed (using Terminals):

Code:
cp -Rp ~/Documents /Volumes/Macintosh Data HD
chmod -R -N ~/Documents
rm -rf ~/Documents
ln -s /Volumes/Macintosh Data HD/Documents ~/Documents
However, when I try and type the symbolic link I get the error:

Code:
"ln: Documents: No such file or directory"
Because of this, the Documents folder on the Dock appears with a big question mark as it cannot locate the new Documents folder.

Any ideas how I can get the link working or if not try and restore the original documents folder and just move the entire Home folder over to the Hard Disk data drive?

(note: I don't have any documents in the folders as of yet so I haven't lost any important info!)
