During the last several years, I’ve used several removable drives, including a 500GB WD My Passport, 32GB Lexar flash drive, and a few others.

Format External Drive For Mac And Windows

Three weeks ago, I bought a brand new 2TB Seagate Expansion to backup my MacBook Pro before I updated to the latest macOS, 10.13 High Sierra (also see those High Sierra issues I encountered).

When I connected the Seagate to my Mac, the drive icon showed up like this.

When I opened it, the default content was all there. Since I wanted to use it on Mac, I clicked the blue logo with the text “Start_Here-Mac”.

It brought me to a webpage on Seagate’s site, where it clearly indicated the drive was initially set up to work with a Windows PC. If I wanted to use it with Mac OS or Time Machine backup (which is my intent), I’ll need to format the drive for my Mac.

I then right-clicked the external drive icon on Mac desktop > Get Info. It showed this format:

Format: Windows NT File System (NTFS)

What is NTFS? I’m not going to explain here; you can read more on Wikipedia. The problem is that on macOS, you can’t work with files saved on an NTFS drive unless you use a paid app Paragon NTFS for Mac.

How to Format an External Drive to Work with Mac (from NTFS to Mac OS Extended)?

Note: The tutorial and screenshots below are based on macOS Sierra 10.12.5. They might be different if your Mac has a different version.

Step 1: Open Disk Utility.

The quickest way to do this is a simple Spotlight search (click the search icon on the upper right corner), or go to Applications > Utilities > Disk Utility.

Step 2: Highlight your external drive and click “Erase”.

Make sure your drive is connected. It should show up on the left panel under “External”. Select that disk and click the “Erase” button, the one highlighted in red in the screenshot below.

Step 3: Select “Mac OS Extended (Journaled)” in Format.

A new window will pop up asking which file system you’d like to format the external drive to. By default, it’s the Windows NT File System (NTFS). Select the one shown below.

Pro tip: If you want to use the external drive for both Mac and PC, you can also select “ExFAT”. Learn more about the differences between these file systems from this thread.

By the way, you can also rename your external drive.

Step 4: Wait until the erasing process is complete.

For me, it took less than a minute to format my 2TB Seagate Expansion.

How to Partition an External Hard Drive on Mac

If you want to create multiple partitions on your external hard drive (in fact, you should for better file organization), here’s a step-by-step guide:

Step 1: Highlight your drive and click “Partition” in Disk Utility.

Open the Disk Utility app and highlight your external hard drive. Make sure you select the disk icon right under “External”. If you select the one below it, the Partition option will be greyed out and become unclickable.

Step 2: Add partitions and allocate volume for each one.

After clicking “Partition”, you’ll see this window. Located on the left is a big blue circle with the name of your external drive together with its volume size. What you need to do next is click the add “+” button to increase the number of partitions on your external disk. Then allocate the desired volume to each partition. You can do that by clicking the small white circle and dragging it around.

After that, you can rename each partition and define a file system for it.

Step 3: Confirm your operation.
