How to Fix USB Drive Incorrect Size Problem
USB flash drives, also known as pen drives, are a common portable storage device that many people carry with them. They are useful for saving and transferring files across digital devices. However, some users have been experiencing a strange issue where their flash drive shows the wrong capacity, with the size being either more or less than the actual size. This has led to a discussion on how to fix the USB drive size issue on forums like Tom's Hardware and Reddit.
Why Flash Drive Showing Wrong Capacity
When a USB flash drive's capacity is frequently reduced, showing a much lower size than its actual capacity, it can be frustrating. However, the good news is that the lost space is still recoverable, and the drive still has its initial amount of memory space. You can restore the original size back, and the free space can be recovered, so don't panic. With a solution, you can restore your USB stick to its full capacity.
You'll see an incorrect USB drive size due to various reasons. Typically, this occurs when the drive's capacity is not accurately reported, often because of a mismatch between the drive's firmware and the host computer's operating system. This can happen when the drive is not properly formatted, or when the host computer's OS is not compatible with the drive's firmware.
- Your computer was infected with a virus
- The flash drive has multiple partitions, but Windows only detects the first one, likely due to a limitation or configuration issue.
- 64GB USB drive cannot be formatted to FAT32 as the maximum size of FAT32 is 32GB. You will need to use a different file system such as exFAT or NTFS to utilize the full capacity of the drive.
- Your flash drive was created to be a bootable disk with a portable Windows operating system on it.
- Unnoticeable space on a disk can consume significant space, including substantial unallocated space, a hidden recovery partition, and invisible shadow files.
To fix the USB drive incorrect size problem, you can either reformat the entire drive or format and recreate the USB drive partitions, which can restore it to its original state.
How to Fix USB Drive Incorrect Size Problem
If your USB drive's size is incorrect, you can try reformatting it using a third-party USB formatting tool or the Diskpart command. This should reset the incorrect size and restore the actual capacity of the drive.
#1. Format USB Drive Wrong Capacity Issue with Qiling Partition Master

However, these native tools are insufficient to resolve USB drive size issues, often resulting in error messages like "Windows was unable to complete the format" or "The format did not complete successfully".
To correct the wrong USB drive size, you'll need to use a third-party USB formatting tool. Qiling Partition Master, a reputable partition magic software, is a great choice.

#2. Fix the Incorrect Size USB Drive Using DiskPart Command
If your flash drive has multiple partitions, you'll need to remove all partitions, format the drive, and then recreate partitions. You can use Qiling Partition Master to delete all partitions and create new ones, but for this task, we'll also explore the Command Prompt, a useful tool for Windows users to troubleshoot issues, including a flash drive showing an incorrect size.
To fix a USB drive's incorrect size problem using CMD, follow these steps: Open CMD as an administrator, type `diskpart`, and press Enter. Then, type `list disk` and press Enter to display a list of all disks, including the USB drive.
Step 1. In Windows 10/8/7, search command prompt and run as administrator.
Step 2. On the Command Prompt window, type diskpart and hit Enter.
Step 3. To list the available disks, type `list disk` and then select the disk number of your flash drive by typing `select disk N`, where N is the disk number of your flash drive. For example, if your flash drive is disk 2, you would type `select disk 2`.
Step 4. Now type the following commands one by one and hit Enter after each:
- clean
- create partition primary
- format fs=ntfs To format the flash drive to FAT32, type format fs=fat32 quick instead
- assign
Step 5. Type exit to close the command prompt.
