Howdy. I recently bought Drive Genius 3 (v3.1 is read on the label). I wasn't able to boot from the disc so I contacted their support - anyone else have that problem? I did hook up two drive chasses to my MBP and did a successful drive cloning from the source disk to the destination (so it's worth the money), but has anybody tried the defragment utility? If so, is it worth the time to use? Thx!
