You can format a 128GB SD card to FAT32 using a specialized tool, as Windows built-in formatting tools may not be able to do so. Qiling Partition Master is a recommended FAT32 format tool that allows you to format your SD card, USB, or external hard drive to FAT32 in just 3 simple steps.
"You're trying to format a 128GB SD card to FAT32, but Windows only lets you format it to NTFS. Unfortunately, FAT32 has a 4GB file size limit, so it's not suitable for large storage devices like your 128GB SD card. However, you can format it to exFAT, which is a more modern file system that supports larger file sizes. If you want to use it as a storage device, you can simply use it as is, or you can try using a third-party formatting tool that supports FAT32, but be aware that it may not be reliable or compatible with your device."
SD cards come in various capacities, ranging from a few megabytes to a few gigabytes. Larger capacity cards often use a different format than smaller ones by default.
Due to the 32GB limit of FAT32, formatting tools like Windows Disk Management, DiskPart, and some third-party SD card format tools will format cards below 32GB as FAT32 and cards above 32GB as exFAT or NTFS.
Many people may encounter issues when trying to format high-capacity SD cards (larger than 32GB) to FAT32, which is required by certain devices, resulting in errors such as "Cannot format 64GB SD card to FAT32" or "Unable to format 128GB SD card to FAT32".
128GB SD card cannot be formatted to FAT32 because FAT32 has a file system limit of 4GB per cluster and 32,768 clusters, which means a maximum of 128GB is not supported. The best FAT32 format tool is not needed here. The recommended format for 128GB SD card is exFAT or NTFS. You can use the built-in formatting utility in your operating system to format the SD card to exFAT or NTFS.
