Several things can go wrong.  Here's a list of things to check:

- Make sure that you newfs the second disc BEFORE you mount it on the root disk

- Make sure you newfs the second disc with sufficient swap space (at
least 30MB)
  If you don't do this, it will never work!

- Never have both disks on at the same time with the same address

You shouldn't need to re-initialize the disk, but you will have to newfs it.
