fat32 not opening

"Hi, I cannot open my USB drive on a Windows 10 computer. However, this drive opens well with my Windows Vista PC, and I can access all my files. The USB drive is formatted in FAT32. How comes it cannot open on Windows 10? Please help".

If you've encountered a similar problem of "FAT32 format not opening," you're at the right place. This article will guide you on why your Windows 10 computer isn't opening your FAT32 USB drive and the possible solutions to this problem. We'll also recommend a third-party tool (EaseUS Partition Master) that you can use to format FAT32.

FAT32 Format Not Opening? Why?

The first reason you may fail to open a FAT32 format is when the partition you need to use is larger than 32GB. This is because Microsoft has limited the maximum file size of FAT32 drives to 32GB. If you try opening a file larger than that, you'll encounter the error "can't open".

Moreover, if you try using File Explorer to format the partition, you'll not see an option for FAT32. On the other hand, formatting a hard drive using Diskpart will display the error: "The volume size is too big." Second, you may fail to open FAT32 on your Windows 10 computer because it's not the first primary partition on your removable drive.

Since Windows 10 doesn't recognize any primary partition apart from the first, it won't allow you to partition it. Lastly, you may fail to open FAT32 on Windows because the removable drive is write-protected. This means the drive is read-only and can't allow you to make changes to it through writing or formatting. 

How to Fix "FAT32 Option Not Available"?

Although it's impossible to open FAT32 format under normal circumstances, options exist to format the disk on your computer. Below are the best options to format FAT32:

  1. Method 1. Using EaseUS Partition Master 
  2. Method 2. By running CMD
  3. Method 3. Using Disk Management

Let's discuss each method in detail. Don't forget to share this list of amazing FAT32 formatting tools to help your friends online so to help them get rid of this issue successfully:

About FAT32

File Allocation Table 32 (FAT32) is a file storage system used on devices that store up to 32GB of data. This file system got introduced in 1977 and currently supports all operating systems, including Windows, Mac, and Linux. It also supports mobile devices.

Due to its compatibility across various devices, FAT32 is considered the more reliable in sharing files between computers. Therefore, all SD cards and USB drives use the FAT32 format. A major setback with FAT32 is that it isn't compatible with storage drives with larger storage space. It also can't store individual files larger than 4GB.

However, the file system is still compatible with additional devices, including:

  • Windows 98
  • CCTV cameras
  • Gaming consoles
  • Smartphones
  • Digital cameras

Built-in compression functions aren't available in FAT32. The file system can work with partitions with a total storage size of at most 16TB. It's also important to note that a Windows 10 computer can't format drives using the FAT32 file system. In addition to FAT32, other standard file systems include NTFS and exFAT.

NTFS is suitable for the latest operating systems, while exFAT is best for devices with low memory and power requirements. The chart below compares the three file systems.
