Ghost 14 image backup

I just installed Ghost 14 on a computer with a 30GB hard drive.  The external drive is 250 GB.  When I created the full computer backup it created several files on the external drive. The first 3 are approx. 4 gb and the last is smaller.  I have Ghost running on another computer and it creates only 1 file which is approx 80 GB. (160 HD with 1.5 TB external)  I've looked at the settings and seem to be missing something. How do I change it to create only 1 file instead of 4?  In the Advanced Options under the Define Backup Wizard, the Divide into smaller files to simplify archiving is NOT checked.  Thank you
