However, if your Mac can't recognize the internal hard drive, or Mac is not detecting it at all, this internal hard drive might have some hardware problems. You can either send it to a local repair store, which could be costly, or say goodbye to this drive and buy a new one.

You can't access a Sandisk, Crucial, or Samsung T3 when the external SSD is not recognized or detected by Mac, whether the external SSD was working for a long time or it's a new SSD you bought recently. However, hard drives not working or showing up issue is so prone to happen even when you unplug the external SSD from the Mac and later on plug in the SSD again. It's definitely frustrating, especially when you have important files stored on it.

How can you fix the unrecognized external SSD and access your files stored on it? You will find the answer and troubleshoot this problem in this post.

Why is external SSD not recognized on Mac?

Various reasons are leading to external SSD not showing up issue on Mac. Here we conclude four main causes as below:

1. The SATA to USB 3.0 adapter/Dock is malfunctioned.

Usually, you need to buy an additional dock, disk case, or SATA adapter to access an SSD drive. During this process, if the externally connected SSD is not recognized by your Mac, it's likely that the adapter is not compatible with the disk's SATA interface, or the dock/drive caddy is faulty.

2. The external SSD is new and uninitialized.

This happens when users externally connect the SSD to backup or transfer files on the internal hard drive. But many newly bought SSDs are not initialized with a file system, which means there is no entrance for macOS to recognize and communicate with this SSD, and for sure, the external SSD won't show up.

3. The external SSD has a file system that can't be recognized by Mac.

Possibly, the SSD that you try to access is formatted with a file system. However, it's not a file system that your Mac can recognize. For example, it is formatted with a Linux file system. In this case, your macOS can't recognize the external SSD surely.

4. New software or firmware needs to be updated.

This happens frequently for Samsung portable SSD T5/T3, because you need to install Samsung portable SSD Software to unlock disk's password and update certain firmware for this SSD. And if the necessary software and extension are not downloaded, you may receive 'No Samsung portable SSD is connected' from its software.

5. The external SSD is not set to show up on Mac.

Sometimes, your external SSD actually is recognized by the Mac, but some setups stop the SSD from showing up in the Finder, on the desktop, or even in the Disk Utility. https://cooldfile447.weebly.com/anydrop-1-3-12.html.

6. The external SSD is corrupted.

Another possible cause is that you have unsafely ejected your SSD, which makes the external drive corrupted after some core data like partition table or file system is damaged. Also, you need to be clear that the life span of an SSD is limited depending on how frequently you use it.

Since all SSDs use SATA interface, so when an external SSD is not recognized by Mac, the first and foremost solution is to check whether the external SSD is properly plugged in. So simply do these checks:

• Try a different SATA to USB adapter and make sure it works by plugging in a different drive.
• Try to connect the external SSD directly to your Mac if it's a type C drive, rather than accessing it via a USB-C adapter.

Tips: If the unrecognized external SSD is a Samsung T5/T3 SSD, and you got the 'System Extension Blocked' and 'No Samsung Portable SSD is connected' messages when executing Samsung Portable SSD Software, simply go to System Preferences > Security & Privacy > choose Allow button next to the message: System software from developer 'Samsung Electronics' was blocked from loading.
