FAT32 is a popular choice for SD card and I prefer it over exFAT as FAT32 remains a widely used file system for SD cards because of its broad compatibility across many devices and operating systems.

1. Excellent Device Support

FAT32 works on Windows, macOS, Linux, Android, cameras, game consoles, smart TVs, and more. Many older and embedded devices only recognize FAT32.

2. Fast and Lightweight

It has low overhead, which means better read/write performance on smaller files—ideal for SD cards used in dash cams, MP3 players, or handheld consoles.

3. Lower Risk of Corruption on Removal

Compared to NTFS or exFAT, FAT32 tends to be more tolerant of improper ejects, making it safer for removable storage like SD cards.

If you can't format SD to FAT32 in Windows 11 from file explorer, then try the command tool instead.

How to Format an SD Card to FAT32 in Windows 11

1. Insert your SD card.

2. Open PowerShell as administrator.

3. Run the following:

format /FS:FAT32 X:

Replace X: with your SD card’s drive letter.

⚠️ This method doesn’t work for SD cards over 32GB due to Windows' built-in limit.

Why don't I have the option to format to FAT32? There are several reasons and this is why you can not format sd card to fat32 in Windows.

1. Windows Limitations
By default, Windows File Explorer and Disk Management only allow FAT32 formatting on drives up to 32GB. This is an artificial limitation—FAT32 itself supports partitions up to 2TB, but Microsoft chose not to support formatting large volumes as FAT32 to push users toward exFAT and NTFS, which are more modern.

2. exFAT Becomes Default
For SD cards larger than 32GB, exFAT is the default and often the only option shown, since it's optimized for flash storage and supports larger file sizes (over 4GB), which FAT32 does not.

If you can not format SD card to FAT32, the built-in command-line tool will help sometimes like 

format /FS:FAT32 (but that often fails for drives >32GB). Please try a dedicated partition manager as it has more powerful features for disk partition in Windows 11/10.

I’ve fiddled with SD cards and USB drives where Windows refused to format to FAT32 that i can't format SD card to FAT32, especially with larger cards. I’ve used reliable third-party tools like GUIFormat or FAT32Format, and as long as I download from reputable sources and follow instructions, it’s generally safe. But if the SD card is suspicious or showing errors, forcing a format might just cause more trouble.

Potential risks When you can't format SD card to FAT32:  
* If you’re not careful and accidentally format the wrong drive or use some third-party tool that doesn’t work right, you could wipe out important data. Always double-check which drive you’re working with. 
* If your SD card is already flaky or physically damaged, forcing a format or using weird tools might make things worse or cause the card to become totally unusable. 
* Sometimes, when you’re trying to force FAT32 on a very large SD card (like over 32GB), it can be tricky. Windows restricts formatting larger drives as FAT32 because it’s not efficient for big storage. Using third-party tools to do this can sometimes introduce bugs or issues if not done properly.

If you’re okay with losing the data (or you’ve backed it up), and you’re using a trusted tool, it’s usually safe. Just be cautious about which drive you select and avoid rushing. If the card is physically damaged or showing errors, forcing it might not help and could make it worse.

Formatting large SD cards (like 128GB) to FAT32 on Windows can be tricky because Windows natively doesn't offer FAT32 formatting options for drives larger than 32GB through File Explorer or Disk Management. This is due to Microsoft’s own design decisions, this is the reason why you can't format SD crad to FAT32 performance and practicality of smaller drives with FAT32.

What should you do if can't format SD card to FAT32

1. You mentioned using diskpart and format, but these may fail due to size restrictions. However, some command-line tools like fat32format (from Ridgecrop) can handle larger drives.

2. Use a Linux live USB or macOS
- If you're comfortable with Linux or macOS, you can:
- Boot into Linux (via Live USB)
- Use GParted to format the SD card to FAT32
- Or use Disk Utility on macOS

Can't format SD card to FAT32? There are several reasons why you might be unable to format an SD card to FAT32 on a Windows computer.  Here are some common causes:

1. File system errors on the SD card:  The SD card might have existing file system corruption or errors.  This is a common problem, especially with older or abused cards.
2. Incorrect partition table:  The SD card's partition table might be incompatible with FAT32 formatting.  This is less common but possible.
3. SD card write protection:  The SD card's write protection switch might be turned on.  This physically prevents the computer from modifying the card.
4. SD card is too full:  Trying to format a nearly full card can cause issues.  Free up space on the card first.
SD card is not recognized by Windows:  If Windows can't see the card at all, formatting won't work.  Try different card readers or ports.
5. Driver issues:  Corrupted or outdated drivers for the SD card reader could be interfering.
6. Permissions:  Windows might be preventing the formatting due to incorrect permissions.
7. Hardware limitations:  Rarely, the SD card itself might have hardware limitations that prevent FAT32 formatting.
8. Boot sector issues:  The boot sector of the SD card could be corrupted, preventing the formatting process.
9. Other file systems already present:  The SD card might contain a file system other than FAT32, which prevents a simple format to FAT32.

Troubleshooting Steps:

1. Check write protection:  Look for a physical write protection switch on the SD card itself.  Turn it off if present.
2. Free up space: If you can't format SD card to FAT32. If the card is nearly full, delete files to free up space before attempting formatting.
3. Check device manager:  Look for any errors or warnings related to the SD card reader in Device Manager. Update or reinstall drivers if necessary.
4. Try different card reader:  If possible, use a different SD card reader to see if the problem is isolated to the current one.
5. Check for errors:  Attempt to run a thorough check on the SD card for errors using tools provided by the manufacturer or Windows.  (This may not be applicable in all cases).
Check for SD card issues in the manufacturer's documentation:  Often, manufacturers provide specific troubleshooting guidance for their SD cards.
6. Try a different computer:  If possible, try formatting the SD card on a different computer to rule out any issues with your current machine.
