Failed to format 2TB hard drive to FAT32 via Windows built-in tools? Why that occurs? How can you successfully format a large hard drive to FAT32 in Windows? This article covers the reasons and fix。

The problem: cannot format large hard drive to FAT32 in Windows

User case: I have a 2TB external Hard Drive that I need to use at home with my Windows 7 PC and at school where I use a Mac. I know NTFS is for Windows only and FAT32 works on both Windows and Mac. However, I have been unable to format 2TB hard drive to FAT32. I have tried in CMD using the format fs=FAT32 quick but it popped out an error message saying "The volume is too big for FAT32". Any ideas?”

The Reason

From the user cases above, we can learn that it is not possible to format large hard drives to FAT32 via Disk Management or Command Prompt. Why? That's because 32GB is the size limit for FAT32 drive partitions. That is to say, if there is a hard drive partition larger than 32GB, it cannot be formatted into FAT32 via traditional formatting methods.
