Would surprise me. If Ashampoo says they're full trials, they usually are. Did you follow the instructions carefully ? You should get a full version anyway. I've been using Ashampoo products for some 10 years now. I get almost daily E-mails, but I rarely fall for their requests to buy this or that. Sometimes you can even decide yourself what you want to pay for a product.
Quality-wise the products are usually average except for their uninstaller. Usually if they offer you a free product they're previous versions, as is prob with this HDD control version since there's a new version. The HDD control only checks internal disks and does not seem to recognize the external one's. They promised/claimed that their new version of the HDD Control would recognize more hard disks. Not true, it still doesn't recognize any externals.
