Besides, there are two copy methods which are insurances when you clone HDD to SSD of
different sizes. First, if you clone smaller HDD to larger SSD or SSD with the same size,
you can do sector by sector
clone which refers to clone all sectors of HDD no matter it is used or
not so that you get a 100% identical copy and AOMEI guarantee the job success even
