Can't Format EXT3 to FAT32/NTFS, How to Solve

Hi, I mistakenly formatted my USB stick as EXT3 by a third-party tool, and now I want to change it back to NTFS, FAT32, or any other standard format for Windows. I used the windows tool but kept seeing the error that I could not format! Does anyone also have this problem? I would appreciate any help resolving this issue.

Don't worry; many users have encountered this problem, and they found that they can't format USB to NTFS or FAT32 on a Windows computer. Please keep calm. Here is a list of reasons why a USB cannot be formatted as NTFS:

  • Bad sector
  • Physical damage
  • Virus or malware infection
  • Locked or write-protected
  • Incompatible operating system
  • Malfunctioning file system errors
  • The USB file format is not supported or compatible with Windows

In your case, if you make sure there is no problem with your USB. EXT3 is incompatible with Windows, which is why you can't format EXT3 USB to NTFS/FAT32. You can turn to EaseUS Partition Master, which allows you to format EXT2/3/4 to NTFS and FAT32. And it is compatible with almost popular Windows versions, like Windows XP/Vista/7/8/10/11.
