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.

If you read my previous post about how to format an external hard drive, you know that I bought a 2TB Seagate Expansion external drive and managed to create two partitions on the disk — one for Mac backup purposes, and the other for personal use.

In this article, I’m going to show you how to backup your Mac data to an external drive. You should backup your Mac on a regular basis, especially if you’re planning to perform macOS updates.

I did this several weeks ago while preparing my MacBook Pro for the High Sierra update. You may also be interested in taking a look at the issues I encountered during that process just in case you also want to upgrade your Mac to the latest macOS.

Please note that the backup tool that I used is Time Machine, a built-in app provided by Apple. If you want to backup your Mac data without using Time Machine, there are also alternatives worth considering.

Where is Time Machine on Mac?

As I said, Time Machine is a built-in app within macOS ever since OS X 10.5. To find it, click on the Apple logo on the top left corner of your screen, then select System Preferences.

In the Preferences Pane, you’ll see the app located between “Date & Time” and “Accessibility”.

What does Time Machine Backup?

Time Machine is definitely the easiest way to backup Mac. In addition, the app is created and recommended by Apple. Once you have a timely backup, it’s incredibly easy to restore all or part of your data in case of accidental deletion or a hard drive crash.

So, what kind of data does Time Machine backup? Everything! Photos, videos, documents, applications, system files, accounts, preferences, messages, you name it: They all can be backed up by Time Machine. You can then restore your data from a Time Machine snapshot. To do so, first open Finder, then Applications, and click on Time Machine to continue.

Be aware that the recovery process can be only be conducted when your Mac is bootable.

A Step-by-Step Guide to Backing up Mac to an External Hard Drive

Note: the screenshots below are taken based on macOS 10.12.5 Sierra. If your Mac has High Sierra or an older version, differences may exist, but the process should look similar to what’s displayed below.

Format An External Hard Drive For Both Mac And Pc

Step 1: Connect your external hard drive.

Format An External Hard Drive For Mac Without Losing Data

First, use the USB cable (or USC-C cable if you’re on a newest Mac model with Thunderbolt 3 ports) that comes with your external drive to connect that drive to your Mac. Once the disk icon shows up on your desktop (if it doesn’t, open Finder > Preferences > General, and here make sure you’ve checked “External disks” to let them show on the desktop), move on to Step 2.

Step 2: Select the disk for backup.

Now open Time Machine (I tell you how above) and select the disk you want to use. I have partitioned my Seagate drive into two new volumes, “Backup” and “Personal Use”, as you see from the screenshot. I chose “Backup”.

Step 3: Confirm backup (optional).

If you have used another disk for backup before, Time Machine will ask you whether you want to stop backing up to the previous disk and use the new one instead. It’s up to you. I selected “Replace”.

Step 4: Wait until the process is complete.

Now Time Machine will start to backup all your data. The progress bar gives you an estimate of how much time is left before the backup is complete. I found it a bit inaccurate: Initially, it said “About 5 hours remaining”, but it only took two hours to finish. It’s worth noting that the remaining time may vary from case to case depending on the write speed of your external hard drive.

It says I have to wait 5 hours

After about an hour and a half, it says only 15 minutes remaining

Step 5: Eject your external drive and unplug it.

When the backup procedure is completed, don’t rush to disconnect your device as this could cause potential disk problems. Instead, go back to the main desktop, locate the volume that your external hard drive represents, right-click and select Eject. Then, you can safely unplug the device and put it in a safe place.

One More Thing

Like any other hardware device, an external hard drive will fail sooner or later. It is advisable to make a copy of the data on your external drive — as they say, a “backup of your backups”! One good option is to use cloud storage services. I now use IDrive (read our full review here), and I really like it because the app is so easy to use, and it also allows me to back up my Facebook albums and photos automatically. Backblaze and Carbonite are also popular options in the market, though I have yet to give them a try.

I hope you find this tutorial helpful. I can’t emphasize enough the importance of data backup these days, especially when my mid-2012 MacBook hard drive died all of a sudden. I’ve also seen cases where my friend’s computer and hard drive failed. You can imagine their desperation. Without a proper backup, it’s really hard to restore data. Although you could try a third-party recovery program like Prosoft Data Rescue and Stellar Mac Data Recovery, chances are they won’t get all your lost data back.

How To Format An External Hard Drive For Macbook

Anyway, the main takeaway I want you to have from this article is this: Backup your Mac with Time Machine and create a second or third copy of those backups if you can.
