Solution 2. Check Finder Preferences

Another common reason your Mac could not be displaying your Samsung SSD is if it isn't set up to show external devices on the desktop. Follow these steps to show your SSD icon-

Step 1. Click on the desktop or open any Finder window.

Step 2. In the menu bar at the top of the screen, click on "Finder" and then select "Preferences."

Step 3. Click the "Sidebar" tab in the Preferences box that appears. Click on the "External Disks" checkbox and you can find it listed as the last item on the Sidebar list. Just scroll down to enable it and this guarantees that when connected, external drives such as the Samsung Portable SSD will show up in the Finder sidebar.

Step 4. Similarly, even in the "General" tab make sure "External disks" is selected. This setting determines whether connected external drives appear on your desktop.


Solution 3. Mount Samsung SSD with Disk Utility

You can try looking for your Samsung SSD file using Disk Utility if the above-mentioned method does not work for you. This method makes use of macOS's disk utility feature to manually mount the SSD.

You can verify that your Mac detects your SSD without any problems by manually mounting the external disk. Just, follow the steps mentioned below:

Step 1. Choose "Application" from the "Finder" menu, then click "Utilities" to choose "Disk Utility."

Step 2. Choose "Show all devices" from the disk utility's left-hand menu.

Step 3. From the left sidebar, choose your Samsung SSD, then click "Mount" in the disk utility window.

Solution 4. Check Samsung SSD File System

Writing to or altering data on disks formatted with NTFS is not supported by macOS by default. Plus, NTFS (New Technology File System) is the primary file system format of Windows operating systems and devices.

Although macOS can read (see) data on NTFS disks, it requires additional software to write (edit or delete) files to these drives. One approach to get access is to enable writable for your NTFS disk using a third-party tool like EaseUS NTFS for Mac.

This utility program's main purpose is to make it easier for macOS users to manage and communicate with external disks formatted in NTFS. Download the tool and build the connection for your Samsung SSD and Mac with one simple click.

Possible Causes of Samsung Portable SSD Not Detected Mac

There are several reasons why your Samsung Portable SSD may not be detected on your Mac. Some of the most common reasons include the following:

  • Hardware connection issues. Most of the time, the problem arises due to a poor connection where data transfer from the Samsung Portable SSD to the Mac isn't possible due to the cable being broken or malfunctioning. You can also have an issue with the port on the Mac or SSD that is broken or incompatible.
  • Software/driver issues. The SSD might not be detected if the drivers needed to connect it to the Mac are out-of-date or incompatible. Plus, sometimes to ensure compatibility, make sure you update to the latest macOS versions and have the latest patches for the SSD's firmware or drivers.
  • File system incompatibility. Certain SSDs might not work with macOS for various technological reasons, such as unsupported file systems. So, you might need to use a third-party app to make the SSD work properly.
  • System settings prevent detection. In addition to all the causes, sometimes Mac's system settings might prevent the driver from being detected. Such as:
  • Energy Saver settings. External drives may not be detected when you try to access them because macOS Energy Saver settings may be set to put them to sleep after a certain amount of inactivity.
  • Security settings. If not set correctly, security mechanisms like FileVault or Gatekeeper may prevent access to external disks.

Knowing these causes of external SSD not showing up on Mac will not only help you to understand the problem better but also help you identify the best possible solution for you. Share this with your friends who might be facing similar issues and keep reading to know the possible fixes.
