Methods to Fix Samsung SSD Not Detected on Mac

1. Check Finder Settings

Because of changes you've made to your settings, your Mac might not recognize your drive sometimes. This problem can be fixed by letting your Mac see other devices. How to do it:

Step 1. Open a Finder, then click Finder on Apple menu. Then choose Settings.

Step 2. Click General and Sidebar, make sure External disks is selected. Then you can see all connected devices on desktop and Finder sidebar.

Click General and Sidebar

2. Reboot Your Mac

Are many apps or processes in the background when you connect your Samsung Portable SSD to your Mac? These may have used up most of the memory on your Mac, making it impossible for your Mac to join.

Remove your SSD from the drive, close all your apps and background tasks, and restart your Mac. After that, connect your SSD again before you do anything else on your Mac. That will give it enough time to find the link.

3. Try Another Cable

Each external SSD has a cable made for that type of SSD and its power needs. So, if you choose the wrong one, your external device might not have enough power to work right, and your Mac computer might not recognize it.

Check for these small problems before you try to fix them. Get a cable with connectors that work with your SSD and a power source that is right for it.

4. Check/Update Your Drivers

If your Mac's drivers are outdated, it might have trouble reading your SSD. As it turns out, users of macOS Big Sur often have trouble with the Samsung T7 not being recognized on Mac M1. Firmware changes are part of the macOS changes, so you must update them. Click on System Settings in the Apple menu to do this.

Click on System Settings

1. Choose General from the menu on the left, then click Software Update in the right pane. Then, do what it says on the screen.

2. You should also get the Samsung Portable SSD program that works with your macOS version. That will make your computer better at using the drive.

5. Format the New SSD

If you bought a new SSD and your Mac won't recognize it, it could be because insufficient space was allocated. Most of the time, you'll need to format an SSD after buying it to work with macOS. How to set up a new SSD on a Mac:

  1. Use the right port (like USB, Thunderbolt, or USB-C) to connect the external SSD to your Mac.
  2. Ensure you've changed the Settings to show external drives.
  3. The Disk Utility can be opened by going to Finder > Applications > Utilities > Disk Utility.
  4. You'll see a list of drives of Disk Utility. Go to the external SSD you want to format and click on it. It might look like a drive that hasn't been cleaned or set up yet.

    Format the New SSD

  5. Click Erase in the action pane.
  6. Configure format settings.
  7. Give the newly prepared SSD a name.
  8. To begin processing, click the "Erase" button.

6. Check Your Mac’s Security Settings

To keep you safe, your Mac may block access to and from devices it doesn't know how to use. Using your Samsung Portable SSD with the Mac, check if your security settings halted the link. Click on System Settings in the Apple menu to do this.

Check Your Mac’s Security Settings

Choose Privacy & Security from the menu, then scroll down the right side until you reach the Security area. The Allow Accessories to Join setting will let you know if it stops you from getting to your SSD.

Choose Privacy & Security

7. Run First Aid

  • Step 1: Go to Finder > Applications > Utilities and open Disk Utility to use First Aid.

    open Disk Utility

  • Step 2: On the left, find your drive and click on it. At the top of the window, click on First Aid. When asked, confirm.

Taking Preventative Measures:

  • Regular Backups: No matter what kind of storage device you use, it's a good idea to back up your files regularly. Time Machine is an easy-to-use choice for automatic backups that comes with macOS.
  • Safe Ejection: Always properly eject the SSD using the Finder option before disconnecting it to keep your files safe.
