The demo does not offer the partitioning function. After several attempts to speak with a human at Prosoft (including several canned email responses that did not address my question), I finally spoke with someone who said 'unfortunately, no, you cannot demo the partitioning function...and no, we do not offer a money-back guarantee.' She went on to say that they felt that if they offered partitioning in the demo, people would just use the demo and then delete the app. I explained that I was a sincerely interested customer, and she said she'd consult management. Shortly thereafter I received the same answer (at least she followed up timely, I'll give her that). In other words, I can either choose to pay $100 for this application for the partitioning functionality (the *only* function I am interested in that TechTool Pro 4 doesn't offer), and if it doesn't work as advertised, that's my loss. Has anyone bought this software and can speak to the partitioning function? Does it work? Any problems or peculiar observations?
