Scenario: “Samsung Data Migration not working”


I just bought a brand new Samsung 840 Series SSD. I am planning to migrate my data from my current desktop’s HDD to the SSD. I am using the Samsung Data Migration software; however, it is not working. I am not sure why this happens? It is stuck at 99% every time. So close to complete but failed.”


Causes and quick fixes to Samsung data migration not working

Samsung Data Migration software is designed with the purpose of helping users quickly, easily and safely migrate all of their important data including current operating system, applications, and other personal data from their existing hard disk to a new Samsung SSD drive in Windows11/10/8/7 (32/64bit).

However many users report their Samsung Data Migration does not start. Why isn't Samsung Data Migration working? The following factors could explain and address the issue as well as other common problems like Samsung Data Migration interrupted, Samsung Data Migration stuck at 99, or 0%, etc.

① Your current Samsung Data Migration version is not upgraded to the latest version.
Under this situation, you can download the latest version of Samsung Data Migration software from its official site.

② There is something wrong with SATA port or SATA-to-USB cable.
Connect the Samsung SSD drive to another different SATA port or SATA-to-USB cable to check if the problem persists.

③ The source disk does not contain operating system.
This software will work only if the operating system is installed on the Source Disk. It will not work on disks that lack an operating system installation. So make sure you are cloning the system disk to Samsung SSD.

④ The source disk contains multiple operating system.
If there are multiple operating systems installed on the PC (e.g. Windows 7 is installed on the C drive and Windows 11 is installed on the D drive), the cloned disk may not function properly.

⑤ The connect Samsung SSD is not supported.
Based on the User Manual of Samsung Data Migration tool, it only supports Samsung SSD 970/ 960 PRO/EVO, 950 PRO, 860 PRO/EVO, 850 (PRO/EVO), 840 (PRO/EVO), 830, 750 EVO, 470 Series. If you connected another series of Samsung SSD as the target disk, the Samsung Data Migration software does not work, either.
Besides, if you are using a Samsung NVMe SSD as the target disk, you should install the Samsung NVMe Driver; otherwise, this software may not work properly.

⑥ You are cloning encrypted disks.
This software cannot clone encrypted disks. In order to clone an encrypted disk, you must first remove the password from the disk.

⑦ Too much data for the target Samsung SSD drive.
The ideal data amount is to occupy around 75% capacity of the target SSD drive. If the transferred data takes more space than the ideal percentage, it will cause an extra burden and lead to the Samsung Data Migration tool not working. So you had better delete some unnecessary data from the source disk first of all and then restart the migration.

⑧ There are some bad sectors on the source disk or SSD drive.
If the source or target disk has some bad sectors or disk errors, the issue might occur, too. You can run the chkdsk.exe tool to check bad sectors or repair the SSD drive via a professional SSD repair tool.
