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.

You should click Cancel instead of Format disk when seeing this prompt. Why? That is simply because the formatting action will damage your data saved on that drive.

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.
• Solve disk problems caused by soft failure.
• Improve disk/system performance greatly.

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.

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

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

Bluestacks download for macbook air. 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:WindowsSystem32drivers.
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.
• OpenDisk 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.
