    Part 2: Which Format to Choose When Formatting?

    This is one of the most overlooked parts of the whole process. Many users do not know the importance of the file system when it comes to storage devices. Everything would be simple if every operating system in the world accepted all file systems. Then you would be able to just use any file system and call it a day. However, that is not the case.

    A file system is like a set of rules that determine how data must be written to the storage device. There are mainly 5 types of file systems available that are in common use.

    FAT32: A file system that has been in business from the early 1980s. They were once the goto file system for formatting windows based devices.

    NTFS: NTFS or New Technology File System is the current standard in windows machines. It is the recommended file format for Windows computers, however, they are not suited for Mac OS.

    ExFAT: A modified version of FAT32 which is capable support higher data transfer bandwidths. They are readable by both Windows and Mac devices.

    HFS+: Introduced in 1998 for Mac systems. It was the most common Mac file format until 2017. HFS+ is not readable by Windows machines.

    APFS: This is the latest file format systems used by apple devices. When compared with HFS+, APFS is made for solid-state storage devices. APFS is only readable by Mac devices.

    Now, when you are formatting a USB drive on Mac, you have an important decision to make. Whether the USB should be readable by windows machines and Mac machines or just by Mac and not readable in windows.

    If you want the USB device to be readable by the both Mac and Windows devices, then you have three options – NTFS, FAT or ExFAT. The NTFS files can be read by the MacOS, but you cannot write anything to the storage device. With ExFAT, you can write and read on both MAC and Windows PCs and is our recommended option for an ultra-portable USB device.

    If you want the storage device to only show up on Mac systems, then format your storage device with APFS.

    Nowadays, when you buy a USB drive, you can use it right out of the box with your Mac. However, unless it’s been designed for use with a Mac, it won’t be formatted using macOS’ preferred file system (either Mac OS Extended or APFS, depending on which version of macOS you’re running).

    That’s because most of the computers in the world run Windows, and Windows uses a different file system, usually one known as Fat32. Drives formatted as Fat32 can be read from and written to by macOS, but it’s not optimal and you’re more likely to run into problems than if you use macOS’ native format. So, if you’ve bought a USB drive that’s formatted as Fat32, or any other format other than Mac OS Extended (also known as HFS+) or APFS, here’s how to format a USB drive on Mac. It’s exactly the same procedure if you need to reformat a flash drive on a Mac.

    How to format a USB drive on a Mac

    1. Plug the drive into a USB socket (if you have a recent MacBook or MacBook Pro that only has USB-C connectors, you’ll need a USB-C to USB-A adaptor).

    2. Open a new Finder window and click on the drive. Make sure it has no files on it that you need. The process of reformatting it will wipe all the data from it.

    3. Once you’ve copied any files you need from the USB drive to your Mac, go to Applications>Utilities and double-click on Disk Utility.

    4. Click on the USB drive in the sidebar and then choose Erase from the toolbar at the top of the window.

    5. In the window that drops down type a name for the formatted drive in the box next to Name.

    6. Choose a format from the dropdown menu.

    7. If you have previously stored sensitive data on the drive, click the Security tab.

    8. Choose a security level using the slider. The further to the right you move the slider, the more ‘passes’ the erase tool will make and the more securely files will be deleted. However, it also increases the time it takes to format the drive quite considerably.

    9. Click Ok then click Erase.

    Tip: You don’t need to erase a whole drive to delete files securely. If you have confidential files or sensitive data you need to remove from your Mac completely, you should use CleanMyMac’s File Shredder. It’s specifically designed to securely delete sensitive data and will render it unrecoverable. You can download CleanMyMac X for free here.

    Which format to choose?

    If your Mac is running macOS High Sierra or later, you have two options for file formats: APFS and Mac OS Extended. Which should you choose? The key point is that disks formatted as APFS won’t be recognized by Macs running versions of macOS older than High Sierra. So if you think you might need to plug the USB drive into a Mac running an older version of macOS, format it as Mac OS Extended.

    APFS is optimized for SSD (solid state drive) such as flash drives, so if you reformat a flash drive on a Mac, you should definitely choose APFS (unless you plan to use it with a pre-High Sierra Mac, of course). Even on hard drives, however, APFS is faster and more reliable than Mac OS Extended.

    Finally, if you plan to use the USB drive as a destination for Time Machine backups, choose Mac OS Extended. Time Machine can’t currently back up to an APFS disk and if you select one for use with Time Machine, it will offer to reformat it as Mac OS Extended. You can, however, backup an APFS formatted disk to a Mac OS Extended Time Machine drive.

    How to format a USB drive to FAT32 on a Mac

    The main reason for formatting a USB drive as Fat32 on a Mac is that you want to be able to use the drive on a Windows PC, as well as a Mac — perhaps to transfer files between the two machines. You may also be preparing the drive for use as, say, a storage device for a media player or to record TV programmes on a TV with a USB port.

    The fact that Fat32 can be read from and written to on both Mac and Windows makes it very versatile. However, there is a significant limitation — individual files have a maximum size of 4GB. So, if you’re using the USB drive to store large video files, you may run into trouble. There is a solution, however, exFAT. Unlike FAT32, exFAT doesn’t have a maximum file limit. Better still, it can be read from and written to on any Mac running Mac OS X Snow Leopard or later and on Windows.

    To format a USB drive in FAT32 or exFAT:

    1. Plug the USB drive into your Mac.

    2. Go to Applications>Utilities and launch Disk Utility.

    3. Click on the USB drive in the sidebar in Disk Utility.

    4. Click Erase in the Disk Utility toolbar.

    5. Type in a name for the formatted disk.

    6. Click on the Format menu and choose either MS-DOS (FAT32) or ExFAT.

    7. Click Erase.

    Your USB drive will now be erased and re-formatted as either FAT32 or ExFAT, depending on the format you chose in step 6.

    It’s very easy to format a USB drive on a Mac using Disk Utility. There are a couple of things you should keep in mind, however. The first is that when you format and disk, you will erase all the data currently on it. So if you need that data, make sure you copy it onto another disk before you start. Secondly, there are several formats to choose from, each with advantages and disadvantage. Use the guide above to help you decide which is right for you.
