No. Cloning a hard drive will not delete everything on the source drive, but it does erase everything on the target drive. If you want to clone your HDD to SSD, everything on the HDD will not be changed, but SSD data will be deleted.

Many computer users want to replace an HDD with an SSD because SSD is more energy-saving and less noise-making and has a faster reading and writing speed, stronger durability, better performance, and reliability. And the easiest way to replace an HDD is cloning.

But cloning a hard drive will delete data on the target, so you need to back up data on the target drive before you start the cloning process. Unfortunately, Windows has no built-in cloning tools to help you finish the tasks. So, you need to use professional cloning software. At this time, the professional disk cloning tool - EaseUS Disk Copy comes to help.
