Thanks for catching the typo. I have corrected the original post.

For what it I worth, after being with TechTool pro through 12 versions, I have yet to convince myself, it offers me enough utility to be worth even the $29.95 upgrade price. I had already dropped DiskWarrior and Drive Genius for the same reason vive and three years ago respectively for the same reason and held onto TTP just in case. But there has been no just in case any one of the three utilities would have prevented or recovered from in more than five years.


If we knew what it was we were doing, it wouldn't be called research, would it?
