“Samsung SSD Data Migration cloning failed”

I recently purchased and installed a smaller Samsung 850 Pro in my computer. My current drive is a 480GB old disk which I have been using for several years. When I load up the Samsung Data Migration software, both of my drives show up in the appropriate sections, my old hard drive as the source and my SSD as the target.
When I start the process, it gets to 77% and then I receive the error message:"cloning failed. "I have tried the troubleshooting solutions recommended by the software and ran the cloning again but I get the same error message at 77% each time. If you have any solutions on how I can get the cloning process to complete, please let me know.

Samsung Data Migration Clone Failed

Why Samsung SSD clone failed and how to fix it?

Because SSD has many advantages over HDD and the most obvious one should be its faster read and write speed, many users decide to upgrade HDD to SSD so as to boost their computer loading time. For Samsung SSD users, I believe the Samsung Data Migration software is their prior choice. However, they may get the problem like the user’s in the scenario “Samsung Data Migration cloning failed”.

This issue can be triggered many factors. For example, there are some bad sectors on the disk; the target disk has been disconnected; there is more than one operating system installed on the device; the a source disk is accidentally converted into a dynamic disk, the target disk is not included in the supported Samsung SSD series. To solve the “cloning failed” issue, you can try the following methods:

1. Check whether there are bad sectors on the disk on the disk and fix them if found. This can be done via running “chkdsk g: /f /r /x” command in Comman Prompt window.

2. Convert the dynamic disk to basic disk: this can be done through Disk Management, but it can only convert an empty dynamic disk to basic one. So you have to delete all volumes first, or you can use a professional dynamic disk converter to finish this conversion without removing any partitions.

3. Defragment the original hard drive: choose “Start”>”Control Panel”>System and Security. Click “Defragment Your Hard Drive”.Click the “Analyze Disk” button.When the analysis is complete, click the Defragment Disk button.

4. Disable page files: right-click “my computer” or “This PC” and select “properties” in the dropdown. In the properties window, select “Advanced system settings”>”Advanced”>”Performance”>”Change” under “Virtual memory”. Uncheck “Automatically manage paging file size of all drives”, select “No paging files” and click “Set button” and click on“OK”.

5. Disable Hibernation mode: run the command prompt and type 'powercfg /hibernate off'. It will disable the hibernation mode.
