Hmmmmm... Let's see, I do on average 4-5 data transfers A DAY (more with the current Apple Seagate hard drive recall) including any and all followup support. So, by my best estimate, I have done over 3500 data transfers in the last few years including at least 400 HDD to SSD transfers. Oh, I also have over half a dozen hardware and software certifications (finishing top of the testing percentile), including 3 from Apple.
Now, who's the fool?, you immature cretin.
Fine, I may have gotten carried away. But I kid you not so many of my clients computers that were HDD TO SSD clones had problems. All the ones that didn't were uncloned fresh installs. That's why I think that. That was a few years ago and I haven't done a clone since.
