When to clone external hard drive to internal?

We are in an era of data explosion, where knowledge, technology, wealth, and production materials are fully digitized. In order to protect our data, there have been many ways to save them. Many people choose to back up their precious data to external disks. External hard drives have many advantages, such as portability, large memory space, and so on. Under what circumstances do users need to clone external hard disk drive to internal hard drive? Below are two cases found in the forum:

◐ Case 1: “The process of cloning an internal hard drive onto an external one is pretty well described by online guides, but I can’t seem to find any info on the opposite. I want to replace my internal SSD with another one (I’m on a laptop so I can’t just plug both SSDs in the same time). I've cloned it's content to an external HDD and I would like to know if it's possible to copy the external HDD into the one installed.”
◐ Case 2: “I want to install the old windows version on my laptop instead of the cracked version which is installed now, the old version is in the external hard drive and the cracked version on the internal SSD. So how can I remove the cracked and install the new. Knowing that no important data in internal.”

In Case 1, the user previously cloned the internal disk to the external as a backup, and now the internal disk needs to be replaced and he wants to clone it back. In Case 2, the user wants to migrate the system from the external disk to the internal disk.

Clone External Hard Drive to Internal

For the above scenarios, it can be solved by cloning. Cloning can not only help us save the internal data to the external drives, but also make it possible to convert external hard drive to internal. Most users know how to clone internal disk to external, but do not know the reverse operation. If you want to know the specific operation, please read on.

Preparations for cloning external hard drive to internal

Before cloning your external hard drive to internal, you have to do some preparations.

  1. First of all, you must connect the external hard drive to your computer.  
  • If it is a desktop, you can install the drive on your computer, so you need a SATA cable and a SATA power cable.

  • If it is a laptop that does not have a second drive bay, you need a SATA-to-USB adapter to connect the external hard drive. Of course, if your laptop has a second drive bay, then you can install the external HDD or SSD on your laptop or connect it via USB port.

  1. Next, you need hard drive cloning software to do the clone. Choosing a right hard disk cloning software may save you a lot of time and efforts.
  2. Thirdly, during the cloning process, the destination disk will be overwritten or deleted, so it's suggested to backup files ahead of time. If not, your data will go after cloning. What’s more, if the destination disk is a system disk, you need to create a system/disk backup in advance so that you can restore your computer to a normal state when a problem occurs.
