What Format Flash Drive For Mac And Pc

How to format a thumb drive for both Mac and Windows The Mac/Windows-compatible ExFat format allows larger file sizes than the old FAT32. Select “Mac OS Extended (Journaled),” or your preferred format type. The former option can help ensure that the USB drive is made fully compatible with your Mac, since most USB drives are preformatted for Windows computers by default.

How to format internal and/or external drive to work properly on Mac and Windows computers?

External data storage devices such as USB flash drives, external Hard Disk Drives (HDDs), and Solid State Drives (SSDs) provide one of the easiest ways to transfer files between separate computers without accessing the Internet. This option is often used when attempting to move very large files. The method is also chosen by people who work with media data that imposes various limitations and automatic optimizations when transferring via Internet. Despite the advantages of using external data storage to transfer content, some experienced users encounter problems caused by the difference between operating systems. This article addresses these issues.

A common issue discussed by users within various technical support forums is that of USB flash drives not working on their computers. This is a cross-platform problem that Windows and macOS users often experience. For example, a photographer may provide you with a USB flash drive with stored photos and videos from your birthday party, but you cannot access them on your system. This is the result of differences between operating systems on computers. Windows and macOS use separate file system formats. PCs with Windows operating systems use New Technology File System (NTFS) while Macs with macOS operating systems use Hierarchical File System (HFS+). By default, USB flash drives and external storage are formatted with the NTFS file system - this works flawlessly on PCs, while Mac computers are able to read data in the format, but struggle to write using this type of storage. Fortunately, there is a simple solution: format your external storage with the File Allocation Table (FAT32) or Extended File Allocation Table (exFAT) file system. In this article, we describe the differences between these two file systems and how to format external storage using a Mac computer.

Which file system to choose - FAT32 or exFAT?

How To Format Flash Drive

As mentioned above, both file systems are compatible with Windows or macOS/OS X operating systems. Naturally, the question is: which should you choose? To make the choice easier, we describe both file systems and their features below.

Starting with FAT32 [on a Mac, known as MS-DOS (FAT)], this file system is fully compatible with all versions of Windows and Mac operating systems. Therefore, even the oldest versions of operating systems such as Windows XP SP1 and OS x 10.5 Leopard are compatible. As well as computers, the FAT32 file system is supported by PlayStation 3, Xbox 360, and most cameras. This particular file system does contain file size restrictions. For example, the maximum size of supported files is 4GB (you cannot write files larger than 4GB). Also, you cannot create a startup drive for Mac computers within storage media that uses the FAT32 file system. If, however, you are not planning to use external storage to transfer large files or create any executable partitions (such as a Mac startup drive) the FAT32 file system might be an option, since this format is supported in all versions of the operating system.

exFAT is a newer file system format and has the biggest advantage when compared with FAT32: there are no restrictions on file or partition sizes stored. Therefore, you can write a file of, for example, 1TB size and create partitions of 5TB within the device. Despite this improvement of available data size, some older versions of operating systems are no longer compatible with this file system format. The oldest versions of operating systems compatible with exFAT are listed below:

Mac OS X Snow Leopard 10.6.5 or later
OS X Lion
Windows XP SP2 or later (with an additional update for exFAT support)
Windows Vista SP1 or later
Windows 7

Unfortunately, as well as some old versions of operating systems, the exFAT file system format is not supported by various cameras, video games consoles, and other devices able to read and/or write to external storage. If you will be using a USB flash drive or external storage device with any of these, the required format is FAT32. Otherwise, if the device is to be used only with computers with modern versions of operating systems, the recommended format is exFAT.

Format the drive with Mac computer

Firstly, bear in mind that formatting the drive will erase all content stored on it. Mac computers are capable of formatting any storage device (internal or external) such as HDD/SSD, USB flash drive, and external storage. Even if the Mac is unable to mount the storage, following this method will enable you to format the storage. Begin by connecting the storage device to your Mac, and then launch Disk Utility using Spotlight. Simply use the keyboard shortcut of Command and Spacebar, type Disk Utility, and then press return. Alternatively, open Finder and go to Applications, open Utilities, and then launch Disk Utility. Select the drive you wish to format from the list in the left sidebar of the Disk Utility window.

Then click the Erase button at the top of the window, in the new pop-up window, and type the name of drive. Then click the drop-down menu beside Format and select MS-DOS (FAT) - the FAT32 file format - or exFAT. These formats are described above.

If you are not planning to use this drive as the Windows startup disk or use it with the oldest version of the operating system, do not change the Scheme. Select Master Boot Record.
