# 2. Free up Your Source Disk or Use a Larger Target SSD

As mentioned above, the “not enough space Samsung Data Migration” issue often occurs when cloning an HDD to a smaller SSD. In this case, you can free up your original hard disk or use a larger target SSD. However, if you don’t have a large enough SSD, then freeing up the source disk is a good choice. For that, you can delete all unnecessary files or uninstall some apps on the hard disk.

Well, if you don’t want to delete any data on the source disk, you can try shrinking its partition to create more free space. Here’s how to shrink the partition using Disk Management.

Step 1. Press the Win + R keys to open the Run dialog box, and then type diskmgmt.msc in it and hit Enter.

Step 2. In the Disk Management window, right-click the partition on the source disk and select Shrink Volume.

Step 3. Enter your desired disk space (such as 500 MB) and click on Shrink to confirm it.

However, you may encounter the “Shrink Volume greyed out” issue when using Disk Management. So, we highly recommend you use a professional partition manager – MiniTool Partition Wizard. It can help you shrink/extend partitions to even non-contiguous unallocated space. Once you free up the source disk space, you can start cloning the hard drive to SSD via the guide above.
