The interface is easy to use but the user guide is not. I was disappointed with the support I got because they did not answer my question at all. Drive Genius was supposed to speed up the system after defrag but it didn't. I also did a scan for bad sectors - in case that was the cause for the slow down - but again Drive Genius did not find any bad sectors. So, it looks like I have to live with this.
But this was not my greatest disappointment. I wanted to upgrade my hard disk to 1TB and in that process, get a larger partition for my boot camp Win 7. I could have gone for Super Duper, Carbon Copy and Winclone but chose Drive Genius because it was supposed to be all in one but in the end, it was not to be. The reviews were also very good so I thought I would get good advice and instructions on how to do that. But it was again not to be. Well, my recourse is to go to the one of local stores to see if they could get it done in another way.
