How to Understand External Hard Drives?

Understanding the basics of external hard drives is important before getting into the placement details. These devices add to the limited space on your Mac's internal drive by acting as extra storage units. External HDDs or SSDs come in a range of sizes and formats so that they can be used for large storage needs, from simple file backups to high-definition video libraries.

Types of External Hard Drives:

There are many types of external hard drives, and each has its way of connecting. Here is a list of the most popular kinds:

  • HDD (Hard Disk Drive): Stores info on spin magnetic platters.
  • Solid State Drive (SSD): Uses flash memory to access info faster and longer.
  • Portable vs. Desktop: Size, portability, and power needs should differ.

How to Mount External HDDs/SSDs/USB Drives/SD Cards on Mac?

Step 1. Connect the external hard drive to the Mac.

The first thing you need to do is connect your external hard drive to your Mac. What kind of hard drive you have will determine which of these ports you use:

  • USB (Universal Serial Bus): The most common type of link, it makes things easy to use by just plugging them in.
  • Thunderbolt: A high-performance choice for sending and receiving data very quickly.
  • FireWire (Legacy): This is an old technology that can still be found on some Macs and EHDs.
  • Network Attached Storage (NAS): Connects to your network so multiple devices can view it.

The type of link will have a small effect on the mounting process, but don't worry - the main steps will stay the same. Once everything is hooked up, ensure the hard drive gets power (if needed) and that all the cables are firmly plugged in.

Step 2. Recognize the external storage device.

Once the physical link is made, your Mac should immediately recognize the external hard drive. To make sure of this, do these things:

  1. Open Finder.
  2. Press Command + N or click on the Finder button in the Dock.
  3. You should see your external hard drive in the "Locations" area of the Finder sidebar. It could show up with your name or the name the maker gave it.
  4. If you can't see the drive, try unplugging it and putting it back in. Also, ensure the drive is turned on, and the cables are connected properly.

Step 3. Mount the External Hard Drive.

Most of the time, Macs immediately mount external drives they recognize. If your drive doesn't mount instantly, though, you can do it by hand using these steps:

Method 1: Mounting via Finder

  • Start up Finder.
  • Click Finder on Apple menu.
  • Choose Settings.
  • Click on the "General" tab in the Preferences window.
  • Click the box next to "External disks" under "Show these items on the desktop." This step ensures that external drives can be seen on the screen and are easy to access.
  • Close the Finder Settings window and go back to Finder.

Now, you should see your external hard drive on the screen. Just double-click on its picture to open it and see what's inside.

Method 2: Mounting via Disk Utility

Disk Utility is a built-in macOS tool for handling disks and volumes. It can mount your external hard drive if you can't see it in Finder.

  • Open Disk Utility.
  • You can use Spotlight to find Disk Utility (Command + Space, then type "Disk Utility" and press Enter) or go to Applications > Utilities to find it.
  • Disk Utility will display a list of all the linked drives and volumes. In the list on the left, look for your external hard drive.
  • Click on the name of the external hard drive to choose it.
  • Choose the "Mount" button from the menu. It looks like a play button.
  • The disk utility will try to mount the drive. If it works, it will show up in the sidebar with a list of its titles below it.
  • To get to your mounted external hard drive, close Disk Utility and go to Finder.

Step 4. Safely Ejecting the External Hard Drive.

It's important to properly eject your portable hard drive when you're done using it to avoid losing or corrupting your data. How to do it:

  • Find the icon for the portable hard drive on the desktop or Finder.
  • Click the drive icon and then right-click or press and hold it.
  • "Eject" can be chosen from the choices that appear.

Troubleshooting: When External Drive Not Mounting on Mac

Technology can be unpredictable at times.  If your external hard drive doesn't mount, do these things:

  • Double-check the Connection: Ensure the external hard drive and your Mac have a tight connection on the wire. If you can, try another USB port.
  • Power Up: Make sure that any external power source your external hard drive needs is plugged in and working.
  • Permissions Peek: In very rare cases, permission problems could stop building. Disk Utility lets you check and change rights (more on this later).
