How to Format a 64GB USB Drive to FAT32 Without Losing Data

Yes, you can format a 64GB USB drive as FAT32. Windows File Explorer usually does not offer FAT32 for volumes larger than 32GB, so use DiskPart or a trusted graphical FAT32 formatter instead. Back up the drive first because formatting permanently erases its contents, and remember that FAT32 cannot store an individual file larger than 4GB.

Before you format: back up the drive and check whether FAT32 is really required

Confirm that the target device specifically supports or requires FAT32. Some newer consoles, cameras, car stereos, and media players support exFAT or NTFS; using one of those file systems avoids FAT32’s file-size limit when the device supports it. Follow the device’s instructions if they specify a partition style, allocation unit size, or maximum supported capacity.

Before starting, make sure you have:

• A Windows computer with an administrator account.
• The 64GB USB drive and a USB port that can read it reliably.
• Another drive or storage location for every file currently on the USB drive.
• The target device’s instructions, if they specify FAT32 settings.

FAT32 cannot store one file larger than 4GB. A movie encoded as a single file above that size will not copy to the drive. The same applies to some backup images, installers, and disc images. Splitting a file may work for a particular application, but many devices cannot use split files. Check the files you plan to transfer before choosing FAT32.

Formatting deletes the partition’s contents. Open the USB drive and confirm that everything you need is backed up somewhere else before continuing.

How to format a 64GB USB drive to FAT32 in Windows

DiskPart can format the full 64GB drive as FAT32 even though File Explorer normally hides that option. The commands below erase the selected disk, so identify its number by comparing the displayed capacity with the USB drive’s actual size.

1. Connect the USB drive and open Command Prompt as an administrator.

Open the Start menu, type cmd, right-click Command Prompt, and choose Run as administrator.

2. Start DiskPart.

diskpart

3. Display the disks connected to the computer.

list disk

DiskPart shows entries such as Disk 0, Disk 1, and their sizes. The USB drive may appear slightly smaller than 64GB because manufacturers and Windows measure capacity differently.

Do not guess the disk number. Selecting your computer’s internal disk in the next step can destroy Windows and your personal files.

4. Select the USB drive by replacing N with its verified disk number.

select disk N

DiskPart should report that the selected disk is now the specified disk. If the size does not match the USB drive, stop and select the correct number.

5. Erase the selected disk.

clean

This removes the partition information and makes the existing data inaccessible through normal file browsing.

6. Create one primary partition.

create partition primary

7. Select the new partition.

select partition 1

8. Format the partition as FAT32.

The quick option avoids a full surface scan and is normally the practical choice for a drive that is known to be healthy.

format fs=fat32 quick

Wait for DiskPart to report that the format completed successfully.

9. Assign a drive letter so Windows can open the formatted volume.

assign

10. Exit DiskPart and close Command Prompt.

exit

Open File Explorer and look for the USB drive. It should appear as an empty FAT32 volume.

Why FAT32 does not appear in File Explorer

Windows File Explorer commonly offers exFAT or NTFS, but its normal formatting interface usually does not offer FAT32 for volumes larger than 32GB. That restriction applies to Windows’ formatting interface; it does not mean FAT32 cannot use a 64GB drive.

If you prefer a graphical utility, use a reputable FAT32 formatter from a known software publisher. These tools can format larger volumes without requiring DiskPart. Select the correct USB drive by checking its capacity, choose FAT32, leave other settings at their defaults unless the target device specifies them, and start the format.

A graphical formatter is easier to use, but it has the same destructive effect as DiskPart. It cannot recover files that you did not back up. Avoid unfamiliar download sites and utilities that bundle unrelated software. If a tool offers to format a different disk, stop and recheck the drive model and capacity before accepting.

Windows may also show FAT32 in some third-party tools under names such as FAT32 or FAT32 (LBA). For a typical 64GB USB drive, the standard FAT32 option is the appropriate starting point unless the target device’s documentation says otherwise.

How to confirm the USB drive is FAT32 and ready to use

After formatting, verify the file system before copying a large set of files or connecting the drive to the target device.

1. Open File Explorer and locate the USB drive.
2. Right-click the drive and select Properties.
3. Check the File system value on the General tab.

It should say FAT32. The capacity shown may be below 64GB, which is normal because Windows reports usable capacity differently from the number printed on the drive packaging.

4. Copy a small test file to the USB drive.

Copy a text document or a small photo, open it from the USB drive, and confirm that it works. Do not use a file larger than 4GB as the test; FAT32 cannot store it.

5. Eject the drive safely.

In File Explorer, right-click the USB drive and choose Eject, then wait for Windows to say it is safe to remove. Connect it to the console, camera, car stereo, or media player only after the drive has been ejected.

The target device may create its own folders or files when it accepts the drive. Do not delete those files unless the device’s instructions tell you to.

What to do if the device still will not read the drive

If Windows identifies the USB drive as FAT32 but the target device does not, formatting is only one part of compatibility. Check the device’s requirements instead of repeatedly formatting the drive.

Older devices often expect an MBR partition table instead of GPT. DiskPart’s clean command removes the old partition layout, but it does not always make your preferred layout explicit. If the target device requires MBR, repeat the process after selecting the disk and use this command before creating the partition:

convert mbr

Then create the primary partition, format it as FAT32, and assign a letter as shown earlier. This still erases the selected disk.

Some devices support only a certain partition size, even when the USB drive itself is larger. If the manufacturer specifies a smaller partition, create one of that size rather than using the entire drive. Allocation-unit size can also matter. Leave it at the formatter’s default unless the device documentation gives a specific value.

Check the files themselves. The device may reject unsupported video codecs, image formats, folder structures, file names, or files over 4GB even though the USB file system is correct. Test with one small file in the format the device claims to support.

Finally, try another USB port or computer. A damaged drive, unreliable cable or adapter, or counterfeit drive can report an incorrect capacity and corrupt copied files. If files fail to copy, disappear, or cannot be opened after copying, stop using the drive and verify it with a reputable capacity or storage-health tool before trusting it with more data.

Conclusion

The format worked when the USB drive shows `FAT32` in its Windows properties, accepts a small test file, and can be safely ejected. Keep every individual file under 4GB, then connect the drive to the target device and let it scan the drive. If the device still rejects it, check its requirements for MBR, partition size, folders, and supported file types before formatting again; repeated formatting will not fix unsupported files or a failing USB drive.

Frequently Asked Questions

Can a 64GB USB drive really be formatted as FAT32?

Yes. FAT32 supports a 64GB volume, although Windows File Explorer usually does not offer FAT32 for volumes larger than 32GB. Use DiskPart or a trusted graphical FAT32 formatter to create the file system.

Will formatting as FAT32 erase everything?

Yes. Formatting removes the files on the selected partition. Back up the USB drive before you begin, and verify the disk number carefully if you use DiskPart.

Why can’t I copy a 5GB movie to the FAT32 drive?

FAT32 has a maximum individual file size of 4GB. The drive can have plenty of free space and still reject a 5GB file. Use exFAT or another file system if the target device supports it, or use a device-specific method for splitting the file.

Should I choose MBR or GPT for an older device?

Older consoles, stereos, cameras, and media players commonly expect MBR, but the correct choice depends on the device. If its documentation specifies MBR, use `convert mbr` in DiskPart after `clean` and before creating the partition.
