FAT32—Compatible with Mac and Windows. However, FAT32 is a legacy file system designed for low
capacity hard drives and it is not recommended for modern hard drives or operating systems. A FAT32
partition can reach up to 32GB when formatted on a Windows PC.
How to choose the file system format
Use NTFS if:
…you connect the storage device to Windows computers, and you don’t need to allow a Mac to write to
the disk.
Use HFS+ if:
…you connect the storage device to Mac computers, and you don’t need to allow a Windows computer to
read or write to the disk. HFS+ is the only format compatible with Time Machine.
Use exFAT if:
…you need to allow both Mac and Windows computers to read and write to the disk.
You can use FAT32 if:
…you connect the storage device to older Windows and Mac computers. FAT32 is not recommended for
modern operating systems and computers.
