Go to the Applications folder on your Mac’s hard drive, then go to the Utilities folder, and launch Disk Utility. Select the drive you want to format. Warning: the following steps will delete any info you currently have on the drive. Click the Erase button. Click the Format menu, then choose either MS-DOS (FAT) or ExFAT. The original FAT file system (or FAT structure, as it was called initially) was designed and coded by Marc McDonald, based on a series of discussions between McDonald and Bill Gates. It was introduced with 8-bit table elements (and valid data cluster numbers up to 0xBF) in a precursor to Microsoft's Standalone Disk BASIC-80 for an 8080-based successor of the NCR 7200 model VI data-entry.
