User case

“Months ago I purchased a Samsung 850 Pro 512GB SSD and moved my C drive from Seagate 500GB HDD to the SSD using the Samsung Data Migration tool. Then I have been using the old HDD to store games. But the HDD that is very slow when playing newer games. So I got a 960 Pro 1TB SSD and planned to used the migration tool to move all the content of my HDD onto it. But now I have run into the issue. The Samsung Data Migration would not let me change the source disk (defaulted to the 850 for whatever reason). Does anyone how to fix it?”

Can Samsung Data Migration change source disk?

Most users might have met the same issue when using Samsung Data Migration tool to transfer data from or to Samsung SSD drive. So, it is possible to change the source drive in the Samsung Data Migration tool? We can find the answer in the below screenshot from its user manual.

In the above picture, we can clearly see that the source disk (HDD or SSD) must contain the operating system installation. In other words, this software only supports migrating data on system disk to another Samsung SSD drive. It will not function on disks that lack an operating system installation.

Therefore, when you use Samsung Data Migration, only the boot disk can be selected, and you cannot change the source disk to some other data disks. Besides, if there are multiple operating systems installed on the PC (e.g. Windows 7 is installed on the C drive and Windows 8 is installed on the D drive), the cloned disk may not function properly. Moreover, you should note only the following Samsung SSD drive can be selected as the destination disk. So you cannot migrate files to other series of Samsung SSD drives, not to mention, other brands of SSD.
