Create user on a disk that's not shared

I have created a user which I want to mount on a separate disk.

Using the command line I would just "mount /dev/sdb1 /home", then I'd add it to the fstab file which appears not to be encouraged.

Please could someone tell me the best way to do it.....Thanks

Answered my own question although not quite sure why you cannot do it via the command line.

You have to use the settings page in users and create a shared folder then change the permissions to your requirements.
