Whenyou get a new external hard drive or a new SD card, you might need to first format it before use. When you format a storage device, the system will require you to choose a proper format. If you are a beginner, you might feel confused, what is the format, and which one should you choose?
The file system is the way the system enables your storage device to store and arrange files. The main difference between all the file systems is how data is stored on the hard drive. Also, they differ from each other in file names, file permissions, and other attributes.
On a Mac computer or in macOS, there are four compatible file system formats: APFS, Mac OS Extended, MS-DOS (FAT), and exFAT. According to Apple's introduction, APFS is the "default file system for Mac computers using macOS 10.13 or later, features strong encryption, space sharing, snapshots, fast directory sizing, and improved file system fundamentals." As for MS-DOS (FAT), it has a better-known name - FAT32.
In this article, we mainly help you distinguish between the two file system formats - exFAT and Mac OS Extended. They are less common than the two earlier-mentioned ones. If you want to know their characteristics, please read on, we will introduce them in the following sections.
ExFAT is short for extended file location table, it was introduced in 2006 and was added to older versions of Windows like Windows XP and Vista. When talking about exFAT, it is necessary for you to know FAT32.
FAT32 is an old file system that is compatible with both Windows system and macOS, which is its biggest advantage. However, its biggest disadvantage is that it does not support the transfer of files larger than 4GB, so most storage devices using this format are USB flash drives.
The reason why to develop exFAT is to solve the problem that large files cannot be transferred in FAT32 format. Like NTFS, exFAT has a larger limit on file and partition sizes, so you can store and transfer files larger than 4GB.
For Mac OS Extended, it has a better-known name - HFS Plus or HFS+. It is the oldest file system used on all Mac computers since 1998. On older versions of macOS, HFS+ is the default file system for all drives. Since macOS High Sierra, Apple has introduced a new file system called APFS, short for Apple File System. It is specialized in SSDs and other flash drives.
When formatting a drive to Mac OS Extended, you can see there are two choices. One is Mac OS Extended (Journaled) and the other is Mac OS Extended (Case-sensitive Journaled). In most cases, you just need to choose the standard format (Journaled) unless you need a case-sensitive system.
If you need to format a USB drive or an SD card, the recommended formats are ExFAT and FAT32 [MS-DOS (FAT)]. If your SD card is 64GB or larger, choose ExFAT, if it's 32GB or less, choose MS-DOS (FAT).
In the main EaseUS Data Recovery Wizard window, there will be a list of the drives connected to your Mac. Select the drive you need to recover lost/deleted files from, and click the "Search for lost files" button.
Note: Before data recovery, you'd better click "Disk Backup" from the left sidebar to create a backup of your Mac to avoid further data loss. After backing up, the software can recover data from the Mac backup, and your computer can wirte new data again.
EaseUS Data Recovery Wizard for Mac will immediately scan your selected disk volume and display the scanning results on the left pane. You can sort the results to find the wanted files if you are looking for certain files.
On Mac computers, there is a built-in disk management tool called Disk Utility. With this tool, you can mount, erase, and format any external hard drive. Here are the steps of how to format a drive in Disk Utility.
That's all about ExFAT and Mac OS Extended. Simply speaking, these two formats are both compatible with macOS. When you need to format a USB drive or an SD card, the ExFAT is a better choice. If you want to format a hard drive, it's better to choose Mac OS Extended. Or, in macOS High Sierra and newer OS, you can choose to format your drive to APFS.
Does exfat work on Mac? Yes. The file system - exFAT works on Mac and Windows PCs. You can easily transfer data from Windows to macOS if your drive is in exFAT format because you don't have to reformat each time constantly.
