Any modern operating system, windows xp/vista/7, linux, osx etc.
Fat 32 was first introduced in windows 95
FAT 16, FAT 32, NTFS (for Win NT, Win 2000, Win XP, won 2003, Vista).
Windows makes use of the FAT and NTFS file systems.
It is the primary file system for various operating systems including DR-DOS, FreeDOS, MS-DOS, OS/2 (v1.1) and Microsoft Windows (up until Windows Me). For floppy disks, it has been standardized as ECMA-107[3] and ISO/IEC 9293.[4][5] Those standards include only FAT12 and FAT16 without long filename support; long filenames with FAT is partially patented. The FAT file system is relatively straightforward technically and is supported by virtually all existing operating systems for personal computers. This makes it a useful format for solid-state memory cards and a convenient way to share data between operating systems.
NetBSD, Windows, and Linux each support both FAT and NTFS file systems.
FAT and FAT32

If you mean creating a new partition on your HDD, the same way you do for a PC. (This is for windows 7, I assume it's similar in XP and Vista) Control Panel > Administrative Tools > Create/Format Hard Disk Partitions
File Allocation Table (FAT) is a computer file system architecture now widely used on many computer systems and most memory cards, such as those used with digital cameras. The FAT file system is relatively straightforward technically and is supported by virtually all existing operating systems for personal computers. This makes it a useful format for solid-state memory cards and a convenient way to share data between operating systems.
FAT is a file system used by MS-DOS and other Windows-based operating systems to organize and manage files. The file allocation table (FAT) is a data structure that Windows creates when you format a volume by using the FAT or FAT32 file systems. Windows stores information about each file in the FAT so that it can retrieve the file later.
Partition Magic is a partition managing software utility created by PowerQuest Corporation. It was changing moving, or copying hard drive partitions without data loss. It also allowed one to change their FAT file systems.
Only 2 GBs. If you want more, go to FAT32, or reduce the size of your partitions.
