But macOS users sometimes have problems with their Mac not mounting an ExFAT drive. That can be not very pleasant, especially if the drive has important data on it. It can be easier to fix the problem if you know the usual causes, like file system corruption, disk errors, old macOS versions, bad formatting, and hardware problems.
This detailed guide examines many possible options, such as reformatting the drive and using third-party software, as well as built-in macOS tools like Disk Utility and Terminal. If you follow these steps, you should be able to fix the problem and access your ExFAT drive again, which will keep your data safe and easy to access.
Understanding ExFAT and Mac Compatibility
The file system ExFAT (Extended File Allocation Table) is often used on external storage devices because it works with both Windows and macOS. While APFS/HFS+ and other native Mac file systems work well with computers, ExFAT doesn't work well with Macs. Know this:
- Limited Permissions: ExFAT doesn't have journaling, which keeps track of changes to the file system. If the drive is removed incorrectly, mounting problems could occur, leading to errors.
- Allocation Unit Size: Macs can only read ExFAT drives formatted with a certain cluster size. If you format a drive on a Windows computer with a size that your Mac doesn't support, your Mac won't be able to read it.
