128GB USB Stick Only Showing 32GB Available, How to Fix?

I recently formatted my 128 GB USB, which stores Windows 10 backup. However, when I checked the USB stick's properties after formatting, it said it only has a capacity of 32 GB. What can I do to get the full capacity?

First, let's check some common reasons why 128GB USB only shows 32GB:

• Formatted as FAT32: The FAT32 file system has a maximum file size limit of 4GB and a partition size limit of 32GB. If your 128GB USB drive is formatted as FAT32, it can only show up to 32GB of storage. 
• Invalid Partition: If the USB drive has an invalid partition or the partition table is corrupted, it may only show a portion of the actual storage capacity. 
• Windows Installation/Recovery Drive: If the USB is used as a Windows installation or recovery drive with specific partitions and storage allocations, it can only show the total capacity for system-related files and recovery partitions. 

No matter which situation you are in, you can format your USB, you can format it as NTFS correctly to access the full capacity. EaseUS Partition Master Free can help format USB flash drives to various file systems without destroying the device. In addition, this free tool can also help you extend the new NTFS partition to show its full capacity:
