Airport Extreme supports FAT16, FAT32, HFS+ and Mac OS Extended (Journaled)
Airport Extreme supports FAT16, FAT32, HFS+ (also known as Mac OS Extended) and Mac OS Extended (Journaled).
FAT16 and FAT32 are older file systems with their origins in the 1970s and 1980s. FAT16 was introduced with the first version of DOS and supported a maximum volume size of 2GB. FAT32 was introduced with Windows 95 and supported larger volumes, up to 2TB. FAT16 and FAT32 are simple file systems that are supported by a wide range of operating systems, including Windows and Mac OS. However, they are relatively inefficient compared to newer file systems and have various limitations, such as a maximum file size of 4GB.
HFS+ is a file system introduced by Apple in 1998. It replaced the earlier HFS file system and offered several improvements, including support for larger volumes and improved metadata structures. HFS+ is also known as Mac OS Extended because it was the standard file system used by Mac OS for many years. However, it is not supported by Windows by default, so it is primarily used on Apple devices.
Mac OS Extended (Journaled) is a variation of HFS+ that includes a journaling feature. This feature improves the resilience of the file system by keeping a log of file system changes, which can be used to recover the file system in case of power failures or other unexpected shutdowns. For this reason, Apple recommends using the journaled version of HFS+ on storage devices used with Airport Extreme. While Airport Extreme also supports the non-journaled version of HFS+, using the journaled version can provide additional data protection.

NTFS and ExFAT formats are not supported
The Airport Extreme (802.11n) and Time Capsule support USB storage devices formatted as Mac OS Extended (HFS-plus), FAT16, or FAT32. However, NTFS and ExFAT formats are not supported.
FAT32 is an older file system that is not as efficient as NTFS but offers greater compatibility with other operating systems. It was originally created for floppy disk storage and was introduced in Windows 95. FAT32 remains the most common file system today due to its usage in memory cards and flash drives. It is also compatible with a wide range of new and old devices, making it the de facto standard for many machines. However, it struggles with large files over 4GB in size and has an 8TB partition limit.
NTFS, or New Technology File System, is the modern file system that Windows uses by default. It was first introduced with Windows XP and offers many advanced features not available to FAT32 and exFAT, including file permissions for security, a change journal for error recovery, shadow copies for backups, encryption, and disk quota limits. NTFS also has theoretically unlimited file and partition size limits. However, its limited cross-platform compatibility makes it ideal only for internal drives running Windows.
ExFAT is a modern replacement for FAT32 and offers greater compatibility than NTFS. It was introduced in 2006 and added to Windows XP and Vista operating systems via a software update. ExFAT offers file and partition sizes up to 128 petabytes and is ideal for storing and writing larger files for use on multiple devices. It is also compatible with modern versions of macOS and Linux distributions running Linux Kernel 5.7 or newer, such as Ubuntu 22.04.
While NTFS and ExFAT offer advantages over FAT32 in terms of file sizes and features, their limited compatibility with the Airport Extreme makes FAT32 the recommended format for USB storage devices used with this router.

Formatting a storage device as Mac OS Extended with journaling is recommended
Mac OS Extended (Journaled) or HFS+ Journaled is a file system format that the Mac operating system uses to manage data on a storage device, such as a hard drive, solid-state drive, or USB flash drive. The "Journaled" feature in Mac OS Extended (Journaled) refers to its journaling capability, which allows it to maintain a circular log or journal of the modifications that have not been committed to the main file system. This prevents the file system from being corrupted during a system crash or power outage.
The procedure for formatting an external hard drive to Mac OS Extended (Journaled) is identical to formatting a Mac OS Extended (Journaled) drive to other formats on a Mac. To format a drive to Mac OS Extended (Journaled), open Finder and launch Disk Utility from the Applications > Utilities folder. Click View > Show All Devices, select the physical disk you want to format, and click Erase. Name the drive and choose a file system format, such as Mac OS Extended (Journaled). Finally, click Erase again.
It is important to note that while Mac OS Extended (Journaled) is compatible with Airport Extreme, it is not natively compatible with Windows. If you need to switch between macOS and Windows, it is recommended to format your drive as ExFAT on macOS. Additionally, if you need to work with both Windows and macOS, you can reformat the drive to exFAT or FAT32. However, if you only need to work with Windows, you can reformat the drive to NTFS.

You can format an external HD on an Airport Extreme Base Station
You can format an external hard drive (HD) on an Airport Extreme Base Station. The Airport Extreme Base Station supports USB storage devices. However, it is important to note that the Airport Extreme Base Station does not support all file formats.
To format an external HD on an Airport Extreme Base Station, you must first connect the HD directly to a Mac or PC. Once the HD is connected to your computer, open the Disk Utility application and format the disk. Be sure to format the drive to HFS+ (also known as Mac OS Extended or Journaled). It is recommended to set the partition scheme to GUID and format the partition to HFS+ as well. This will ensure that the Airport Extreme Base Station can recognize the drive.
After formatting the HD, you can connect it to the Airport Extreme Base Station. You can then designate the HD as your Time Machine backup destination. To do this, open Time Machine preferences through System Preferences or the Time Machine icon in the menu bar. Specify the drive, and your first backup will begin. It is recommended to connect your machine directly to the Airport Extreme Base Station using a network cable for the initial backup, as this process can take a significant amount of time.
Additionally, you can use the Airport Extreme Base Station to create a simple Network-Attached Storage (NAS) volume. This allows you to access files stored on the HD directly from your iOS devices without the need for a computer. To set this up, connect your formatted USB HD to the USB port on the Airport Extreme Base Station. You can then use FileBrowser to access and play files stored on the HD. With this setup, you can even lock your iOS device, and the video will continue playing on your TV.
