couple of  ideas:

1) Call silver lining and make sure the version you have supports
the drive you are using. I know their earlier versions did not 
support large drives. Besides, I know 5.2 is old. I've seen 5.32.

2) Do you have perhaps both drives terminators installed ?

3) Try it without the other drive.
