For those who use both Microsoft Windows and Apple macOS, having a single external hard drive that is compatible with both operating systems could be very beneficial. The problem with this is that by default, Windows and macOS use different formatting styles that aren't directly compatible with each other. Windows uses the NTFS (New Technology File System) format, while macOS uses either HFS+ (Hierarchical File System Plus, a legacy format used by older versions of macOS) or APFS (Apple File System, a newer format used by recent macOS releases.)

There are some third-party solutions that can read Mac-formatted data on Windows and vice versa, but some of these are costly and may not offer 100 percent compatibility for all files. Instead of buying one of those programs, a better solution is to set up your external hard drive so that it is compatible with both your Windows machine and your Mac. This lets you create an external hard drive for Mac and PC that doesn't require any additional software to function.

Understanding Formats

When a hard drive is formatted, any data that's currently on the drive is erased and a new file system is set up for a computer's operating system to use. The file system determines how the operating system manages data, how that data is stored and what sort of storage blocks are used on the hard drive. The file system organizes the data in such a way that the operating system can access and use what it needs, so if the file system isn't supported by the OS then it has no way to actually access and read the data. In most cases, a drive with an unsupported file system won't even show up in Explorer or Finder unless you have set up your computer specifically to view the unsupported drives.

This is why it's so tricky to format for Windows and Mac on the same hard drive. Assuming that you have newer computer models and are running recent versions of Windows and MacOS, the file systems used by your computers are incompatible. This is due largely to file system optimizations that were made with a specific operating system in mind, though competition between Microsoft and Apple may play a part in the proprietary nature of their respective OS file systems. With that said, there are a few ways to format a single external hard drive for both Mac and PC use without losing data or corrupting files.

How to Format for Mac and PC

While Windows and macOS primarily use their respective proprietary file systems, both support other file systems as well. In particular, both Windows and macOS support the exFAT (Extended File Allocation Table) file system that is commonly used for flash drives and other rewritable storage. This means that you can take an external hard drive and format it with the exFAT file system and it will then be readable and writable to both you_r Windows PC and your Ma_c.

If you choose to do this, however, it is important to avoid changing the settings of the file system too much when you format. By default, exFAT uses 32KB and 128KB data clusters when reading and writing (respectively); you can change this up to 32GB per function when choosing the formatting settings. MacOS doesn't support exFAT cluster sizes greater than 1024KB, however, so if you increase the cluster size significantly then the drive will only be usable by your Windows computer. Additionally, some users have reported issues with reading exFAT drives on Windows PCs if the drives were formatted on a macOS computer; while this does not happen for all users, to avoid potential problems you may wish to format the drive on your Windows PC instead of your Mac.

Dual Formatting

If you have some specific need for NTFS or APFS/HFS+, or you simply don't wish to use exFAT to format your external drive, there is another option available to you. Instead of formatting the drive with a single file system, you can create two partitions on the drive and format each of those with a different file system. This will reduce the amount of space that's available for either Windows or Mac files, but it will ensure that you have storage space on your external drive that's in your preferred format regardless of which computer you're on at the time. If choosing this route, make sure that you have sufficient space on the hard drive to make the dual partition worthwhile. Starting with a 500GB hard drive would only give you 250GB of space per partition, assuming that the partitions were equal; you may be better off going with at least a 1TB hard drive unless your storage needs are minimal.

This can be done starting on either computer, using the operating system's disk management tools to create two partitions on the drive. If you have any data currently on the drive you should back it up before partitioning, since it could become corrupted or deleted during the process. Either shrink the current volume and add a new partition on the empty space or create two partitions if the drive hasn't been formatted yet. (If there is already a partition there but you wish to start fresh you can delete the current partition and treat the entire drive as empty space.)

Once the two partitions are created, use your Mac to format one of the partitions in either APFS or HFS+ and use your Windows PC to format the other partition in NTFS. Each computer will only be able to access its appropriately-formatted partition, though disk management software should be able to see the other partition as well if needed.

Reformatting the Drive

Should you decide at some point that you no longer want an exFAT or dual-partitioned drive, you can reformat the external drive for use by Windows or macOS at a later date. If there are multiple partitions on the drive then you should probably delete them to avoid accidentally formatting only one of the partitions instead of the entire drive. Even if there's only a single exFAT partition on the drive, make sure that you back up any files or programs that the drive contains since reformatting will erase everything contained on the drive. While there are ways to recover files and data after a format, these are not always 100 percent effective and data may be damaged, corrupted or lost completely.

When you reformat the drive, it will be similar to the process of installing the file system with which you previously formatted the drive. Connect the drive to the computer you wish to use it with and format it in the appropriate file system to meet your needs. On a Windows PC, this would be NTFS; on macOS it would be APFS(or HFS+ if you're using an older Mac.) Of course, if you're moving from a dual-partitioned drive to a drive with a single partition on it then you could choose to format the drive with exFAT instead. Just make sure that you don't adjust the cluster sizes too much if you're hoping to retain the ability to use the drive on both a Mac and a Windows PC.

Summary :

Want to format an external hard drive for Mac and Windows PC? Do you know how to do this work easily? This post will show you specific methods to make external hard drive compatible with Mac and PC, which are easy and safe to complete.

Quick Navigation :

As we know, external hard drives are widely used to backup data or interchange files among different computers. Well, is there an external hard drive that could be shared between Mac and Windows PC? Of course, there is. Actually, most external hard disks could be compatible with Mac and PC as long as you format them correctly.

Why Need to Format External Hard Drive for Mac and PC

To put it simply, if you want to share external hard drive between Mac and PC, you need to format an external hard drive for Mac and PC.

Currently, hard drives for Windows PC are always formatted with NTFS, while hard disks for Mac are formatted with HFS+. However, when we connect a NTFS formatted disk to Mac, Mac OS X doesn't allow us to write files to the drive neither edit files, though it can read a NTFS drive. Similarly, Windows OS will ask us to format the HFS+ formatted drive when we connecting such a disk, let along edit files saved on HFS+ formatted hard disks unless we resort to third party programs.

But luckily, there are file systems well supported by both Mac and Windows PC, and they are FAT32 (it might be called MS-DOS on Mac) and exFAT. As long as we format the external hard drive to one of these 2 file systems, it can be shared between Mac and Windows.

Further Reading

Both FAT32 and exFAT have advantages and disadvantages.

FAT32: FAT32 works with all versions of Windows, Mac OS, Linux, game consoles, etc.

However, single files on a FAT32 drive can't be larger than 4GB. If your external drive saves files larger than 4GB or you plan to save larger files to this drive, converting to FAT32 is not recommended.

In addition, a FAT32 partition must be not more than 32GB if you create it in Windows Disk Management. Of course, there is free partition manager that can help create a FAT32 volume up to 2TB, which also functions correctly.

exFAT: exFAT has very large file size and partition size limits, which means it's a good idea to format your external hard drive to exFAT.

Nevertheless, a lot of users complained that exFAT is slow, and they highly suggest using FAT32 if you can avoid file size constraints.

Three Options for Accessing NTFS Drives on Mac

Paid Third-Party Drivers

Some paid third-party NTFS drivers for Mac can be used to access NTFS drives on Mac. They work well and they have better performance than the free solutions which will be mentioned in the following part. Paragon NTFS for Mac is such a driver.

Besides, you can also use the paid third-party file system converters to convert NTFS to FAT32 or exFAT which are compatible with both Mac and PC. MiniTool Partition Wizard is one representative.

Free Third-Party Drivers

FUSE for macOS is a free and open-source NTFS driver that can enable write support. But, this solution is slower relatively. And the automatically mounting NTFS partitions in read-write mode can be a security risk for your Mac computer.

Apple’s Experimental NTFS-Write Support

The Mac OS has an experimental support for writing to NTFS drives. Usually, it is disabled by default and needs some messing around in the Mac terminal to enable it.

It doesn’t work properly all the time and could lead to potential issues with your NTFS file system. For example, it had corrupted data before. Thus, we don’t suggest using this tool and we believe it is disabled by this reason.

Here, we recommend using the paid third-party tools since they are easy-to-use and can do good work for you.

Then, we will introduce these three options for you in the following content.

The Best Paid Third-Party Driver: Paragon NTFS for Mac

Paragon NTFS for Mac can write, edit, delete, copy, or move files on NTFS volumes from your Mac computer. It offers a 10-day free trial. If you want to use it all the time, you need to pay for it.

With it, you don’t have to fiddle with terminal commands to mount partitions manually. Additionally, it can mount partitions automatically and safely. More importantly, it can code with the potential corruption. If you purchase a Seagate drive, you can even get a free download of Paragon NTFS for Mac.

All in all, it does its works well and gives you good user’s experience.

The Best Free Third-Party Drivers: FUSE for macOS

FUSE for macOS is a free solution to access NTFS on Mac. But it is less secure.

If you want to make automatically mount NTFS partitions in read-write mode on Mac, you need to temporarily disable the System Integrity Protection and replace one of Apple’s built-in tools with a binary that is more vulnerable to attack. Thus, your Mac is in danger when using this driver.

However, you can use it to manually mount NTFS partitions in read-write mode if you never mind using the Terminal. This will be safer, but you need to do more work. You can go to google the steps and see how complex they are.

Apple’s Experimental NTFS-Writing Support: Don’t Do This, Seriously

Although we mentioned this method in our article, we still don’t recommend it because it is the least tested. It is just for educational purposes, and it is available on Mac OS 10.12 Sierra. Perhaps, it will be unstable forever.
