Why do we need Samsung Data Migration OS only?

Samsung Data Migration (SDM) is a data migration tool that comes with Samsung SSDs like Samsung 850 EVO. It helps users migrate operating system and data from the existing storage devices to the new Samsung SSD without reinstalling. 

Usually, users want to clone OS for:
◤ 1. The purchased Samsung SSD doesn’t have enough space. Surely, shrinking partitions, deleting files, and uninstalling programs are helpful in cloning larger disk to smaller one. However, moving OS only is more direct.
◤ 2. The older hard drive is good enough to be secondary storage. The arrangement usually happens on desktops or laptops that have two available disk bays. The combination makes full use of HDD’s and SSD’s advantages. Performance improved and storage saved, why not?

How to use Samsung Data Migration to clone OS only?

Here comes the brief guide to cloning C drive only to Samsung SSD. Connect or install the Samsung SSD and make sure it can be detected by Samsung Data Migration. If not, you may want to turn to Samsung SSD not detected in Windows 10 for more tips.

Step 1. Install and launch Samsung Data Migration. Click Start in the lower-right corner to continue.

Step 2. You’ll see the source disk, i.e. the existing disk which contains the operating system and the Samsung SSD. Pitch on C drive only. You’ll see only C drive on the Samsung SSD in virtual states. Click Start again to continue.

Select C Drive

Step 3. A warning dialogue will pop out saying all data on the new Samsung SSD will be lost. Confirm the disk and click Yes to start the process. Wait for the process completes.

Step 4. When you see “The data on the Source Disk has been successfully cloned to your Samsung SSD” in green font, the process completes perfectly. Shut down the PC and boot from the cloned Samsung SSD.

Cloning is complete

▶ Tips: Do not disconnect any of the disks during the cloning process. Make sure the power supply is sufficient for cloning.

It is quite simple and fast to perform Samsung Data Migration with a boot drive. In most cases, the process will complete as expected. However, some users report that the cloning failed. It reports the target disk has been disconnected and which is not true. In a few cases, you’ll get Samsung Data Migration stuck at 99 percent, 0 percent, or 100 percent. All in all, finding a reliable workaround is necessary if you happen to face one of those troubles.
