Why can't I format my SD card to FAT32?
“I have a Sandisk Ultra 64GB SD card and cannot get it to a FAT 32 format. Tried few links, no success. I am using Windows 10. Is there any way possible to achieve this?”
Do you have a Raspberry Pi?
Maybe you have another tech gadget that requires FAT32 format, but all you have is a 64GB SD Card. This article solves that problem, how to format 64GB exfat SD card to FAT 32.

We found windows DOES NOT let you format any device over 32MB into FAT32.
This makes formatting an SD card of 64GB hard to handle.
We tried using CMD/ command prompt to achieve this, and got an error saying “Windows was unable to complete the format”.
With Windows 10, you have an option to use this command:
format /FS:FAT32 X:
Replace the letter X with the drive letter for the external device you wish to format and hit Enter.
Note – This process may take several hours.
If you do not have Windows 10, and are on Windows 7 or a variation of it, there are other options.
