Thank you for contacting us.
Our EASEUS Partition Master can set partition size to resize it, for further analysis, please send us the screenshot of our EASEUS Partition Master where you can't set it, and send us the screenshot of Windows Disk Management (Please right click "My Computer" and choose "Manage" -> "Storage" -> "Disk Management").
You said that your partition miss 4096 Byte when you clone your partition/disk with our product, do you mean that the partition size is reduced? Normally, if the destination disk is large or equal than the source disk, after you clone it, the partition size will not be changed. If the destination disk is less than source disk, after you clone it, the partition size will be resized automatically.
Your problem is very strange, generally our product will not cause this problem, for further analysis, please download EASEUSReporter.zip, unzip it, run EASEUSReporter.exe in the EASEUSReporter folder and send Report.zip as attachment to us.
The follow is the operation process:
Click "Next"->"I accept this agreement"->"Next"->"Select iffy disks or partitions"->"Next"->"Send".
You can also send Report.txt as attachment to us manually (you will find Report.txt in the EASEUSReporter folder after you finish running EASEUSReporter.exe).
