MacOS High Sierra: Why you can't format an internal SSD with HFS+ format But you can downgrade and reformat for an older version of macOS. Start up your Mac from it, and then use Disk Utility. How to Format or Reformat SSD on Mac? By Shirly Chen, 2017-12-01. A Solid State Drive is primarily used on Mac machine. If you want to recycle a SSD, formatting is the.
So, you just bought an external hard drive or a portable SSD and wanted to use it on your Mac. But somehow, macOS doesn’t allow you to write data to the drive.
That’s all because it’s been initialized with Windows NT File System (NTFS), which is primarily for PCs. Apple Mac machines support a different file system.
In this post, I’m going to show you how to format your external drive for a Mac compatible file system i.e. Mac OS Extended (Journaled). Just follow this easy step-by-step guide and you’re all set.
Important note: If you have useful files stored on the external drive, be sure to copy or transfer them to another safe place prior to formatting. The operation will erase all data and your files will be gone for good. You could use a recovery program like Data Rescue to retrieve them, but the odds of recovery vary.
Pro tip: If your external drive has a large volume, like mine – a 2TB Seagate Expansion. I highly recommend you also create multiple partitions. I’ll also show you how to do that below.
Most External Hard Drives Are Initiated with NTFS
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.
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.

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.
Once you hit “Apply”, a new window pops up asking for your confirmation. Take a few seconds to read the text description to make sure it reflects what you intend to do, then click the “Partition” button to continue.
Step 4: Wait until it says “Operation successful.”
To check whether the operation is really successful, go to your Mac desktop. You should see multiple disk icons show up. I chose to create two partitions on my Seagate Expansion — one for backup, the other for personal use. You can find more info in this post: How to Backup Mac to an External Hard Drive.
