In most cases we recommend you select MicrosoftвЂ™s exFAT format: this will give you full read and write access in both Windows (Vista or later) and OS X (Snow Leopard 10.6.5 or later).If you need compatibility with systems that are older than this, youвЂ™ll need to fall back to the ancient FAT32 format. You can choose this from the drop-down menu in WindowsвЂ™ Format dialogue, or in the Erase pane of Disk Utility. Ive tried APFS, Jounaled, Exfat and no luck.To use your USB disk on both Windows and OS X, therefore, youвЂ™ll need to use a different filesystem.

However, this can have a negative impact on performance, especially if youвЂ™re using a mechanical disk drive. In practice though, most of the files on your USB drive will probably be many megabytes in size, so the impact of wasting a few kilobytes here and there is negligible.If you plan to save lots of small files to your disk then reducing the allocation unit size might be a good idea. A file thatвЂ™s only 1KB in size will still occupy 4KB of space, while a 5KB file will take up 8KB, and so on. Simply put, this determines the size of the chunks in which storage is allocated for your files: if you choose 4096 bytes (the NTFS default), every file thatвЂ™s saved to that disk will be allocated space in multiples of 4KB.Slicing up disk space in this way isnвЂ™t perfectly efficient. How to format a USB drive: allocation unit sizeAs well as choosing a disk format, Windows also invites you to specify an вЂњAllocation unit sizeвЂќ. For historical reasons, Windows wonвЂ™t offer FAT32 as an option if your disk is larger than 32GB, but you can format a disk of any size by opening a Command Prompt and typing format h: /fs:fat32 /q, where h: is the letter of your removable drive and the /q parameter specifies a quick format вЂ“ assuming you donвЂ™t want to wait around for Windows to check each sector of the drive for errors.
