Can't Shrink the 3 TB USB Drive, How to Fix?

I have a 3TB USB drive with a single partition, and I want to shrink it to create a second partition. However, I can only shrink 700 MB, while the hard drive showed 1.2 TB is available to shrink. What should I do?

The Windows built-in tool will not let you shrink the disk as there are system files, which you need to seek the help of third-party software. EaseUS Partition Master is the expert in coping with the inability to shrink volume issue. Its "Resize/Move" tool allows users to extend, shrink, and remove partitions easily.
