How to Format a Hard Drive For Both Windows and Mac

By Melanie Pinola 29 December 2015

Want to use one external drive for both your Windows PC and your Mac? One hurdle you’ll face is that, by default, these platforms use different filesystems. Windows uses NTFS and Mac OS uses HFS and they’re incompatible with each other. However, you can format the drive to work with both Windows and Mac by using the exFAT filesystem. Here’s how.

In this guide we’re using exFAT instead of FAT32, another filesystem that both Windows and Mac can read and write to, because FAT32 has a maximum 4GB file size limit whereas exFAT can work with files as large as 16EB (exabytes). exFAT also performs better than FAT32.

You can format the drive from either the Mac or the Windows machine. However, if you want to use part of the drive for OS X’s Time Machine backups, you should do this from the Mac, since there’s an extra step to make the drive compatible for Time Machine.

How to Format an External Drive in OS X

1. Connect the drive to the Mac.

2. Open Disk Utility. The easiest way to do that is hit CMD and the spacebar at the same time and type in Disk Utility to find the program.

3. Select the drive you want to format.

4. Click Erase.

If you don’t plan on using the drive for Time Machine, skip steps 5 to 11 below and continue with step 12.

5. Give the drive a descriptive name and leave the default settings: OS X Extended format and GUID partition map. These will format the drive in OS X’s HFS+ filetype so it will be compatible with Time Machine.

6. Click Erase and OS X will format the drive.

7. With the drive selected in Disk Utility, click Partition.

8. Enter the amount of space you want to set aside for Time Machine. In this example, we’re shrinking the Time Machine partition to 128 GB instead of allowing Time Machine to take up the whole drive.

9. Click Apply.

10. Select the new untitled partition so we can format it as exFAT for use with both Mac and Windows.

11. Click Erase.

12. Give the partition a name and select exFAT for the format.

13. Click Erase to finish.

Your exFAT-formatted drive or partition can now be used for both Windows and Mac. Note that using a drive frequently between Windows and Mac could increase the chances of file corruption, so make sure you have backups of the files on the shared drive and be extra careful about safely ejecting the drive before disconnecting it from your computer.

How to Format an External Drive in Windows

The instructions below are for Windows 10, but other versions of Windows from Windows 7 and up can also format an external drive as exFAT for use with Mac as well.

1. Connect the drive to your Windows PC.

2. Open the Disk Management tool. You can do that by typing «disk format» or «disk management» in Windows search or going to Control Panel > Administrative Tools > Create and format hard disk partitions.

3. Right-click on the external drive’s partition or unallocated space you want to format and choose New Simple Volume…

4. Follow the wizard to choose a volume size.

5. Assign a drive letter.

6. Choose exFAT as the file system in the Format Partition screen.

7. Give the volume a new name.

8. Click Next.

9. Click Finish.

Windows will format the drive as exFAT and you’ll be able to use the drive on both Windows and Mac.

Many people doubt that whether they can read Mac drive on Windows. Some took action: they removed the drive from Mac and connected it to a Windows PC properly. But after connecting the Mac-formatted drive to Windows, a prompt window will pop up automatically on the screen, saying that they need to format the disk before use.

What Does Formatting a Hard Drive Do

Some users said they clicked on the Format disk button by mistake when seeing the prompt window mentioned above; they were wondering if there’s any way to help them recover a formatted hard drive. Luckily, the answer is yes.

What does disk formatting mean?

Formatting a hard disk/drive refers to delete all the file & folders save on a drive and set a certain file system for it. The formatting action is performed to prepare a data storage device (including hard disk drive, solid-state drive, USB flash drive, and SD card) for initial use. Two of the most obvious results of formatting a hard disk are: deleting data and changing file system.

Besides, there are also other benefits of disk formatting:

• Get more space on disk.

What about Windows 10 read Mac drive? Please read the following sections.

Can a Mac external drive be read on a PC?

A lot of people are wondering whether they can read Mac drive on Windows 10 with freeware. In fact, there is both free and paid software to help people read Mac drive on PC easily, without formatting the disk. I’ll introduce some of the useful software you can use on Windows 10 to read files and folders from Mac-formatted drive.

3 is suitable for reading HFS & HFS+; choice 4

5 is used to read APFS on Windows.

Choice 1: HFSExplorer

HFSExplorer is completely free; it’s a basic application designed to help users read Mac-formatted hard disks and disk images. HFSExplorer gives support to various file systems: HFS (the Standard file system on Mac), HFS+ (the Extended file system on Mac OS), HFSX (the Extended Mac OS file system with case sensitive file names), etc.

What Does HFSExplorer Allow You to Do

• Browse volumes on Mac by using a graphical file system browser.
• Check the volume related information.
• Extract files you need (copy files to Windows hard disk free).
• Mount & read disk images like .dmg and .sparsebundle.
• Create disk images from the volume on Mac.

The partition schemes including Master Boot Record, GUID Partition Table, and Apple Partition Map are supported by HFSExplorer.

Attention!

You need to install Java first if you don’t have it on your PC since it’s required (Sun’s Java SE runtime environment version 5.0 or greater in which OpenJDK works fine).

HFSExplorer: Launch error

No Java runtime environment found. HFSExplorer cannot function without Java.

Press “OK” to open up http://www.java.com where you can download a Java runtime environment for your system.

You should just click OK as prompted to download & install proper runtime environment when seeing the window above.

How to Use HFSExplorer to Read Mac Hard Drive on Windows

1. Connect the Mac-formatted drive to your Windows PC.
2. Run & use HFSExplorer as administrator.
3. Select File from the menu bar.
4. Choose Load file system from device from the submenu. You can also press Ctrl + L.
5. Click Autodetect to load the drive.
6. Choose the files & folders you want to view on Windows.
7. Click Extract.
8. Select a folder as the destination.
9. Expand the folder to read files on Windows PC.

Attention:

• HFS/HFS+/HSFX partitions can all be detected by using HFSExplorer.
• You can also Select a device or Specify device name manually in step 5.

If the connected external hard drive is not showing up on PC, you can’t detect it in step 5. You must make it appear in Windows first.

Is there any other hard drive reader for Windows? Of course, yes; please move on.

Choice 2: Apple HFS+ Drivers

Another way to access HFS + files in Windows 10 for free is installing Apple HFS + drivers.

Steps to Read Mac Drives on PC with Apple HFS + Drivers

First, you should make sure you don’t have Paragon or MacDrive (the hard drive readers I will talk about later) on your Windows computer. If you do, please remove them now.

Second, you should download the correct Windows driver package to your local drive.

Third, you should configure your Windows as follow.

1. Go to the default download path (Downloads folder) to extract the downloaded zip file.
2. Find AppleHFS.sys and AppleMNT.sys files.
3. Copy them by pressing Ctrl + C (you can also do it by right clicking & choosing Copy).
4. Go to this path: C:\Windows\System32\drivers.
5. Copy them by pressing Ctrl + V (you can also right click on any blank area & choose Paste).
6. Navigate to the downloaded folder to find Add_AppleHFS.reg file.
7. Open the .reg file to bring up a Registry Editor prompt window.
8. Click on the Yes button and then click OK.
9. Restart your computer to make changes take effect.

Fourth, you should connect the Mac-formatted drive to your PC -> open File Explorer (also called Windows Explorer) -> locate that drive under This PC -> access files you want.

Choice 3: HFS+ for Windows

Though the Paragon HFS+ for Windows is a paid hard driver reader, you’ll love it after using.

What Can Paragon HFS+ for Windows Do for You

• The speed is fast and the performance is stable.
• The Mac file systems are integrated into Windows File Explorer.
• It provides full read and write access to Mac drives formatted with HFS, HFS +, and HFSX (just like other drives in Windows).
• It allows Windows programs to read from or write to the Mac-formatted drive on Windows.
• There are additional features that worth the cost.

How Much Does It Cost

The Paragon HFS+ for Windows is sold on the official website for $19.95 with a single seat license; $49.95 with one license worked on 3 PCs.

If you don’t want to spend money in reading Mac drive on Windows, you should download the trial edition; it is free for use for 10 days. You can access, copy files from or to the Mac drive during this period; it’s enough.

Choice 4: MacDrive

If your Mac drive is formatted with APFS (Apple File System), you won’t be able to read Mac hard drive on Windows because there are no free apps designed for it. But you have many choices of paid applications to access & edit Mac drive files on Windows; MacDrive is a popular one designed by Mediafour.

Merits of MacDrive

• It is used to help users read data from and write data to Mac disks from Windows directly.
• You can read both APFS and HFS+ drives in File Explorer.
• It allows you to create and partition Mac disks on your Windows.
• A graphical interface is offered for Mac-formatted drives verification, format, and repair.
• It’s a trusted solution which can date back to 1996.

The only drawback of MacDrive seems to be the selling price is higher than some similar tools. You need to pay $49.99 for the Standard version or $69.99 for the Pro version.

Is it worth the price? Yes, if you have such needs; it also includes unique features like support for Mac-formatted RAID disks.

Choice 5: Paragon APFS for Windows

Paragon also designed an APFS for Windows app for reading APFS Mac drive on Windows; it is considered as one of the main competitors of MacDrive.

Features of Paragon APFS for Windows

• It provides read and write access to Mac drives formatted with APFS.
• It also allows you to access and edit compressed and cloned files (you can only access the encrypted volumes without making any changes).
• It gives support to auto-mounting at start-up; the partition tools of MacDrive are not included in this app.

The biggest disadvantage of Paragon APFS for Windows when compared to MacDrive is the HFS+ support. The biggest advantage of Paragon APFS for Windows over MacDrive is the price – it costs only $49.95 for one license worked on 3 PCs.

Of course, there are many other tools available for you to read Mac drives on Windows (10/8/7, etc.).

Bonus Tip

You can format your Mac hard drive to exFAT, which supports both Windows and Mac OS X. In this way, you can get full read and write access to exFAT drives on Windows without any additional third-party software.

The only thing you need to worry is that the data on Mac drives will be removed. So you need to turn to MiniTool Power Data Recovery as mentioned in part 1 to recover the files you need after formatting.

How to format a hard drive? Basically, there are three ways.

• Right click on the drive in File Explorer -> choose Format.
• Open Disk Management -> right click on the target drive -> choose Format.
• Format Partition with MiniTool Partition Wizard – a professional disk manager.

Final Thoughts

Though you can’t access a Mac-formatted drive on a Windows computer directly, there are useful ways and tools to help you read Mac drive on Windows easily. Please just follow the steps mentioned above and choose the tool depending on your needs.
