Common File Systems for Mac and PC
The file system is one of the most important part for an external hard drive because it manages how your files are stored and retrieved. So, every hard disk needs a proper file system, including desktop drives and portable storage devices like external hard drives, USB flash drives and SD cards. However, different file systems have different advantages and disadvantages. So before you know how to format a hard drive, you should know the pros and cons of each file system.
1. FAT32
FAT file system includes three major file system variants but the majorly used one is FAT32. FAT32 is commonly used in floppy disks, SD memory cards, USB flash drives, digital cameras, as well as many portable and embedded devices.
Pros
- Works universally with all versions of Mac, Windows, Linux, game devices, as well as other devices supporting a USB port.
Cons
- Doesn't support a file size larger than 4GB and a drive partition size larger than 32GB on Windows.
- Doesn't support the drive partition larger than 2TB on macOS.
2. exFAT
exFAT is a good option for external hard drives (e.g. Seagate Backup Plus Slim), especially for large-capacity removable storage devices. It also is frequently used in flash memory drives such as USB flash drives and SD cards. exFAT is easily often implemented in firmware that has low memory and low power requirements, such as cameras, mobile phones, media players, etc.
Pros
- Supports the largest partition and file sizes by today's standards.
Cons
- Not compatible with too much old operating systems.
- Not a good option for drives less than 32GB because it can't maximize space utilization.
3. NTFS
NTFS is a proprietary journaling file system developed by Microsoft. It is used as the default file system of Windows system hard drive (e.g. Windows 10). NTFS does well in data security based on its encryption, access permission control, and log file.
Pros
- Improved performance, reliability, and disk space use.
- Performs better in protecting data security, data management.
- Compatible with all versions of Windows and latest hardware.
Cons
- Read-only in macOS and the disabled-by-default write support for NTFS in macOS is unstable.
4. Mac OS Extended (HFS+)
HFS Plus or HFS+ is a journaling file system developed by Apple Inc. It's the startup disk’s default file system before macOS High Sierra. It also frequently used as Time Machine backup external hard drives of WD, Seagate, etc.
Pros
- Supported by all versions of Mac OS X and macOS.
- Has journaling, compression, and encryption features.
Cons
- Has no access permission control.
- Perfoms slow or crash in dealing with a large number of files.
- Harder for data recovery when an HFS+ hard drive is corrupted.
5. Apple file system (APFS)
APFS is the new proprietary file system of Apple. It has been known to increase read/write speeds on solid-state drives (SSDs), as well as increase storage space due to the way in which it calculates the available data on disk.
Pros
- Allows full-disk encryption with single or multi-key encryption for added security.
- Efficient in management of free storage space
Cons
- Not good for Time Machine backup due to no support for hard links to directories.
- Can only be used on macOS 10.13 and above.

For instance, you would know why exFAT is better for camera SD cards, or why NTFS is better for external backup drive on Windows 10. In a word, you can format or reformat your external hard drive per your requirement, either for Mac and PC.

If you don't format the external hard drive correctly, it won't work to the utmost extent. For instance,Windows uses NTFS, while Mac uses HFS+ or APFS. Out of the box, Windows can't read or write to HFS+/APFS drives and Macs can't write to NTFS drives either.

When should you choose FAT32 file system?

FAT32 works with almost any operating system as well as video game consoles, Android USB expansions, media players, and other devices. However, FAT32 can only support files up to 4 GB in size. So, If all your files on the external hard drive are smaller than 4 GB, and the drive itself is smaller than 2 TB, then FAT32 is a better choice for you to use the hard drive on Mac and PC.
When should you choose exFAT file system?
Similarly, exFAT is also a widely compatible file system. The difference is that exFAT has no limitations on file size and hard drive size. So, when the external HDD you want to used for both Mac and PC is larger than 2 TB, exFAT is the best choice.

When should you choose NTFS file system?
Some users would prefer to the features of Windows NTFS file system. However, naturally, Disk Utility can't format external hard drive to NTFS.

What to do if you can’t format the external hard drive on Mac?
Usually, to format the external hard drive as FAT32 or exFAT, you are advised to do this on a Mac computer via Disk Utility. But if you have formatted the external hard drive under the Windows system, it would cause some inconvenience. You can't add or re-partition volumes of the external hard drive again on Mac. In this case, your only choice is to backup your files and reformat the whole disk.
How to partition an external hard drive for Mac and Windows PC?
Except for having the whole external hard drive formatted, you can also split this disk with two partitions. One is formatted with the file system that is compatible with macOS, another partition is compatible with Windows conversely. By this means, you can use all the advantages each format has on the respective system.
Warning: Still, you need to back up files on this drive before you begin to create two separate partitions to work for Mac and Windows PC.
For some Mac models, the partition option would be greyed out in Disk Utility. So, we suggest that it's better to use a PC to partition an external hard drive for macOS and Windows. Here are the steps to partition an external hard drive for Mac and Windows PC, which is a little tricky.
Step 1: Connect the external hard drive to your PC and then launch Disk Management.
Step 2: Check if the external hard drive is initialized or not.
If the drive is not initialized, you need to initialize the external hard drive with Master Boot Record (MBR). Then you can create two new partitions. You need to format one of them as NTFS for Windows use and format the other as your wish.

If the external hard drive is initialized, you need to right-click the disk to check if it's an MBR external hard drive.
- If you see Convert to GPT Disk in the context menu, be it greyed out or lighted, it’s an MBR hard drive. Then you can create two or more partitions. And you need to prepare one partition for NTFS file system, and reformat with any file system.
- If you see Convert to MBR Disk in the menu, it's an GPT hard drive. In this case, you need first backup files, delete the existing partitions, then click the Convert to MBR Disk button. Then, you can create two new partitions. You need to format one partition as NTFS for Windows use, and then format the other randomly.
Step 3: Up to now, there should be at least two partitions on the external hard drive. And one of them (the NTFS one) is ready for Windows use. Then, you need to safely remove the external hard drive and plug it into a Mac.
Step 4: Open Disk Utility and select the other partition (not the NTFS one) under the name of your external hard drive.
Step 5: Click Erase on the top, choose Mac OS Extended format when it asks, and chose Erase to finish.
Up to now, the external hard drive will have two partitions. One is HFS+ formatted for Mac, and the other is NTFS formatted for Windows.
By creating two separate partitions, you can use this external hard drive on both Mac and Windows. You won't be able to write to the Mac partition from your Windows computer, and vice versa. Thus, it's a good solution for people who need to swap between two operating systems but with separate work.
Make external hard drives compatible with Mac and PC without formatting
Many famous external hard drives like Seagate Backup Plus Ultra Touch and WD My Passport are pre-formatted with NTFS. However, the NTFS file system is a hassle for users who need to use the same external hard drive on both Mac and Windows. The external hard drive is not letting you add files if you use an NTFS external HDD on Mac. It will be read-only and you can't write to this drive normally in this case.
Many users don't know this and use the external hard drive directly. And when they want to reformat the hard drive to use it interchangeably, only to find that files on the drive are erased as well.
Then, can you solve external hard drive read-only without formatting?
Definitely! If you want to use NTFS formatted external hard drives on Mac, software like iBoysoft NTFS for Mac that might be helpful.
