Majority of computer users own at least one external hard drive these days. While it’s always a good idea to format the external hard drive with NTFS because of its advantages, sometimes you might have to format your external hard drive with FAT32. For instance, if you want to transfer files from a Mac to your external hard drive, you need to format the drive in FAT32 as Mac OS X doesn’t support transferring files to NTFS drive (doesn’t support writing to NTFS). Although one can always right-click on a drive, select Format, and then select FAT32 as file system, Windows doesn’t show FAT32 file system option when you are trying to format a drive that is larger than 32GB. So how to format an external drive with a capacity of more than 32GB with FAT32? There are a couple of ways to format your external hard drive in FAT32, even if it’s larger than 32GB. The best method is to use the native Command Prompt to quickly change the file system to FAT32.
