Samsung Data Migration Stuck at 99%, 100% or 0%? Fix it Here!

Why Samsung Data Migration Stuck at 0%, 99%, 100%, etc.?

Samsung Data Migration (SDM) is an application that allows you to transfer files and folders from PC to Samsung SSD. Data Migration software transfers all existing files and programs from your existing HDD or SSD to a new Samsung hard drive such as Samsung 850 EVO SSD, Samsung 840 Pro SSD, etc.

The Samsung data migration stuck issue is a common and annoying problem encountered by many users. It can stop at 0%, 99% or 100% when users try to clone their HDD to an SSD or a new drive for system and data transfer. The exact cause of this problem is usually difficult to determine. But it is usually due to several reasons:

• Insufficient storage space. If the SSD you are transferring data to does not have enough storage space, the migration may get stuck.
• Problems with the cable. A damaged or improperly connected cable can also cause problems with migration.
• Drive failure. Most users usually transfer their data when the drive shows signs of failure, which is one of the reasons why Samsung data migration gets stuck.
• Transferring large files. Longer transfer times for large files may make it seem like the migration is being disrupted.

Fixes for Samsung Data Migration Stuck Issue

Here are a few quick solutions to try before moving on to the slightly more complicated ones for Samsung Data Migration stuck at 99% issue.

• Make sure the cables are properly connected at both ends and that they are not damaged. If you have spare cables, try using them for the transfer.
• Verify that the SSD you are transferring the files to has enough free storage space. In general, it is recommended that you transfer no more than 75% of the SSD's capacity and keep the remaining space free.
• Reboot your computer and start the migration process again.

If none of these work, go to the next listed fixes.

Fix 1. Disable Device Encryption

If you are having problems with Samsung Data Migration stuck at 99%, it is possible that your device is encrypted and causing the cloning process to fail.

1. Press Windows + I to open Settings, choose Privacy & security from the navigation pane, and click on Device encryption. Then, disable the toggle button next to Device encryption.

2. Click Turn off at the confirmation prompt that appears.

3. When finished, restart your computer to make these changes take effect.

Fix 2. Check Hard Drive with CHKDSK Command

If your hard drive is corrupted, data transfers from the failed drive are likely to be jammed and not completed. You can run the CHKDSK command to check the health of the internal and external storage devices connected to your computer. If the problem is with the drive itself, this tool will identify and repair it. Once the scan is complete, verify that the Samsung Data Migration is still stuck at 99%.

1. Press Windows + R to open Run dialog box, type cmd in the text field, and then press Ctrl + Shift + Enter.

2. Now, paste the following command and hit Enter to run CHKDSK command.

After knowing the information about this alternative, you can refer to consider using it to migrate data from Samsung SSD. It has a very user-friendly interface and the operation is very easy. Even a computer novice can follow the step-by-step instructions to complete it.

You need to install this software on your computer first. Then connect the target disk to your computer.

★ Useful Tips of Cloning:

🚩 Edit Partitions: It allows you to edit partition size on target disk as you wish. Also, it supports converting the disk partition style. Checking “Sector by sector clone” option will make this option unavailable.

• Copy without resizing partitions: It will not resize the partition size.
• Add unused space to all partitions: It will reallocate the unallocated space to each partition of the target disk, appropriate for the disk size.
• Manually adjust partition size: It allows you to extend unallocated space to any partition on the destination disk as you want. 
• Convert the destination disk from MBR (GPT) to GPT (MBR): It helps to convert the partition style of the destination disk if it is different from that of the source disk.

🚩 Sector By Sector Clone: by checking this option, AOMEI Backupper will copy every sector from the source to the target, whether it is used or not. It requires the target disk to be equal to or larger than the source disk.
