You may wish to use an external FireWire or USB hard drive to store your Aperture Library, referenced images, or Vaults. Here are some suggestions on preparing the external hard drive for best performance with Aperture. Many external hard drives come pre-formatted as FAT 32. This is a native Windows file format that can be read by Mac OS X, but is not ideal for use with Aperture.

Before you begin to use your new external hard drive with Aperture, reformat it to the Mac OS Extended file system:

1. Be sure your drive is attached and mounted.
2. If you have already written any data to the drive, back it up before proceeding to the next step.
3. In the Finder, choose Go > Utilities. The /Applications/Utilities folder will open.
4. Launch Disk Utility.
5. Click the icon for your external hard drive in the sidebar on the left.
   


6. Click the Erase tab along the top of the window.
   


7. From the Volume Format menu, choose Mac OS Extended (Journaled).
   


8. Enter a name for the external hard drive in the Name field.
9. Click the Erase button.

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.

• How to format a startup drive for a Mac If you want to format a drive that will be used as your Mac’s startup disk, the procedure is a little different from formatting it for use as a secondary.
• Want to format a hard drive for Mac and PC compatibility? You have to set it up correctly before getting starting. Mac OS Journaled is the formatting option for Mac and NTFS or MS-Doc is the.

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.

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.

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.

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.

How To Format A Hard Drive For Mac And Pc

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.

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.
