Isn't it annoying when you have a bunch of free space on your USB Drive, but you can't use it because it is not showing its full capacity on Windows? This issue can occur in your Drive due to various reasons, but it can restrict you to access your Drive properly. Thus, to use your Drive properly, you are required to understand the issue and how to restore the USB drive to full capacity on Windows. 

Why My USB Drive is Not Showing Full Capacity in Windows?

Let's have a look at the various reasons causing your USB Drive to not show full capacity in Windows:

How to Restore USB Drive to Full Capacity in Windows 10/8/7?

It's easy to restore your USB Drive to its full capacity and on Windows, the only condition is it shouldn't be physically damaged. You can easily achieve the objective by using one of the methods listed below, but these methods will erase all of your data from USB Drive, thus, it's recommended to take a backup.

Method 1. Restore USB Drive to Full Capacity Using CMD

You can try the Command Prompt on your Windows to restore USB Drive to its full capacity. All you need to do is to follow the commands carefully.

Step 1. You can search "CMD" from the search panel on your Taskbar, or you can go to "Start" and navigate to the "Command Prompt (Admin)" option depending on the version of windows you are using i.e. 7/8/10.

Step 2. Once the Command Prompt window is open, you need to process a few commands. Type "diskpart" and press Enter. After the given command is processed, type "list disk" and process it by pressing Enter. The latest command should list all the drives and disks connected to your System, including the USB Drive you want to restore to full capacity.

Step 3. After all the drives are listed, you need to Enter the command "select disk #" to select the disk you want to restore to full capacity. ("#" in the command "select disk #" should be replaced with the Number or Letter of the Disk you want to restore.)

Step 4. After the selection of the disk, give in the command "clean" to wipe the disk. Once it's cleaned successfully type the command "create partition primary" and hit Enter. This will form a new partition on your USB Drive.

Step 5. Once the partition is created, you need to Enter the command "format fs=fat32 quick" to format your newly created partition to the FAT32 file system.

Method 2: Format USB Drive to Original State with Disk Management

Disk Management is another integrated feature of your Windows system that lets you restore your USB drive if you are unable to format the USB stick to full capacity to its original state. Restoring your USB Drive to its original state will also restore it to its full capacity.

Step 1. Go to the search panel on the Task Bar of your home screen on Windows, and search for "Disk Management" or "diskmgmt.msc". Click on the topmost result to go to the "Disk Management" window.

Step 2. On the "Disk Management" window, locate the USB Drive that you want to restore to full capacity. Right-click on it, and click on the "Format" option from the context menu.

Step 3. You will see a pop-up window. Configure the parameters for formatting, choose FAT32 or exFAT file system, uncheck the "Quick Format" option and click "OK". This will initiate the formatting process including the treatment of Bad Sectors on your Drive.

Wait for the formatting process to reach 100%. Once completed, your USB Drive will be formatted to its original state. This will restore USB Drive to full capacity on Windows, but you will lose all of your data.
