Can you format a 128GB SD card to FAT32? Don't worry if you are unable to format a 128GB SD card, USB, or external hard drive to FAT32 using Windows built-in formatting tools. On this page, you will find the best FAT32 format tool - EaseUS Partition Master with detailed steps to format SD card to FAT32 within only 3 steps.

How Do I Format a 128GB SD card to FAT32

"A few months ago, I bought a SanDisk 128GB SDXC card and formatted it to exFAT for my Android phone. And now I want to format it to FAT32 so I can use it as just a storage device. But the problem is that Windows only allows me to format it to is NTFS. So, I was wondering that if it is possible to format 128GB SD card to FAT32. If yes, how can I do it?"

As a storage device, SD card is available in various capacities ranging from a few MBs to a few GBs. SD cards of larger capacities usually use a format that differs from the cards of smaller capacities by default:

  • SD (micro SD): 128MB - 2GB, FAT16 (default format)
  • SDHC (SD High Capacity): 4GB - 32GB, FAT32 (default format)
  • SDXC (SD Extended Capacity): 64GB - 2TB, exFAT (default format)
  • SDUC (SD Ultra Capacity): 2TB - 128TB, exFAT (default format)

Due to the max size limit of FAT32 (32GB), the Windows disk management tool, the DiskPart format command, and many third-party SD card FAT23 format tools will format cards below 32GB as FAT32, and cards that are above 32GB as exFAT or NTFS.

As a result, many people may run into problems, such as "Cannot format 64GB SD card to FAT32" or "Unable to format 128GB SD card to FAT32", when they need to convert the file system of the high capacity SD cards (larger than 32GB) to FAT32 so as to be supported by certain devices.
