“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.”

Possible causes & quick fixes

Samsung Data Migration software is designed with the purpose of helping users to 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 Samsung SSD drive. But the following factors could trigger Samsung Data Migration not working and other common problems like Samsung Data Migration stuck at 99, or 0%.

> 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.

> 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.

> 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 extra burden and lead to Samsung Data Migration not working afterwards. So you had better delete some unnecessary data from the source disk first of all and then restart the migration.

>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 chkdsk.exe tool to check bad sectors or repair the SSD drive via a professional SSD repair tool.

Alternative to Samsung Data Migration

If you tried all the fixes above but did not get satisfactory result, you can switch to AOMEI Partition Assistant Standard, which is a free but nice Samsung Data Migration alternative. Compared with Samsung Data Migration which only supports Samsung SSD drives, AOMEI Partition Assistant can help you clone HDD/SSD/USB flash drive/SD card to any branded SSD drive in simple steps. Besides cloning an entire disk, it even can clone a single partition to another drive (HDD or SSD).

Now download the free disk cloning software and see how it clones one disk to SSD drive in Windows 10/8/7/XP/Vista.

Step 1. Connect your Samsung SSD drive to the computer and ensure it is detected. Install and run AOMEI Partition Assistant Standard to enter its main interface.

Step 2. Right click the source hard disk and select “Copy Disk” on the left panel.

>> You can tick “Optimize the performance of SSD” to optimize SSD writing and reading performance.

>> All data on the chosen Samsung SSD drive will be deleted during the process, so please ensure you have backed up important files in advance.

Step 5. Here you can resize partitions on the cloned Samsung SSD, or keep the default settings and click “Next” to continue.

Step 6. Then you will be brought to the main interface, where you will see all partitions have been cloned to the selected Samsung SSD drive. To actually implement this operation, you need to click “Apply”.


With AOMEI Partition Assistant Standard, you can easily avoid “Samsung Data Migration not working” issue.

As the demonstration above, it can easily clone system disk to SSD drive as long as both the source and destination disk are MBR disk styles. If you upgrade to Professional edition, you can break that limitation and clone system disk from MBR to GPT, GPT to MBR or GPT to GPT SSD drive, and moreover, you can migrate only OS drive to SSD drive.
