10 Fixes for USB Not Showing Up on Mac

The reasons behind the problem of a USB device not showing up are various, including the USB port is not working, USB drive corruption, virus infection, macOS faulty, etc. So, to figure out the effective solutions for your own case, you need to take time to have some basic check, exclude the irrelevant issues, identify the potential risk, and finally solve it!

Important
As losing the access to data is the most direct impact of Mac not detecting a USB drive, you might need to perform USB data recovery on Mac.

Fix 1. Change the USB-to-Mac connection way

Have you tried to restart your Mac once or twice? Before taking further measures, don't forget the most efficient way to tackle commonplace hardware glitches that arises from time to time. If this operating system restarting fails to solve the current problem, move on to check the physical connectivity issue step by step.

Step 1. Plug the USB drive out from the not working USB port and change to the other USB port. Try all the available USB ports on your Mac.

Step 2. Did you use a USB connection cable or a USB-C adapter? If yes, take the USB drive out, and directly plug it in the USB port.

Step 3. Is there the other Mac computer available to you? If yes, try to connect the USB drive to this computer. Is it showing up normally?

Step 4. For SD card owners, the common way to connect an SD card to a Mac needs a card reader. If changing the USB ports did not work, try to change a card reader for a new round of tests.

The four steps of troubleshooting a USB drive not showing up on Mac are very basic, however, quite helpful in most cases. Each step can help us exclude the issues of a bad/loose connection, a not working USB port, a lack of power, and other superficial phenomenons.

Fix 2. Change settings for Mac detecting an external hard disk on the desktop

Occasionally, your Mac has already recognized the USB flash drive but not shown it on the desktop. Thus, you should go to Finder > Preferences > General and make sure the 'External disks' option is ticked. Then you'll see the USB flash drive showing up on Mac desktop.

Fix 3. Change settings for Mac recognize an external hard disk in the Finder

Finder is the other access for us to check a connected external drive on Mac. If your flash drive or external hard drive is not showing up there, go to Finder > Preferences > Sidebar, and under Locations, you need to tick the option 'External disks'. By selecting this option, we can make sure that the connected external USB hard drive or flash drive will normally show up in the Finder.

Fix 4. Check the USB drive in System Information

When you cannot find the USB drive on the desktop or in the Finder, try to look for it in the System Information section, which is usually a hidden place for average Mac users.

Step 1. Go to Applications > Utilities > System Information.

Step 2. Check if the system detects the USB drive. Click 'USB' on the left panel, and you can also check the USB flash drive information.

Fix 5. Reset USB ports on Mac to detect a USB drive

Step 1. Restart Mac computer, press the Command +Option+P+R keys until the Apple logo appears.

Step 2. Press Command+Option+Esc keys to close all applications that are not responding.

Step 3. Plug the USB which is not showing up to your Mac computer. If it doesn't show up, click Apple icon and select 'Sleep'.

Step 4. Wake up the computer after a few seconds by pressing any key.

Step 5. Shut down the Mac, unplug the power cord, reattach it after 15 seconds.

If this doesn't work, we should suspect the corruption issue at this moment. Don't give up and try to do some repair by yourself.

Fix 6. Repair USB flash drive with First Aid if it doesn't show up

Step 1. Go to Applications > Utilities > Disk Utility.

  1. Step 2. Select USB flash drive on the left panel of Disk Utility, and click 'First Aid' at the top toolbar and click 'Run'. Disk Utility will repair any errors on the drive automatically.

Step 3. Select the USB drive and click 'Unmount' at the top toolbar, unplug the USB and plug it back in 10-15 seconds.

Fix 7. Check and fix errors in a not recognized USB with Terminal

Step 1. Open Terminal in Utilities, type:diskutil list and press Return.

Step 2. Find the disk number of your USB flash drive, type: diskutil info disk2 and press Return. (Replace 2 with the disk number of your USB flash drive.)

Step 3. Type: diskutil eject disk 2 and press Return.

Step 4. Type: diskutil list and press Return.When the USB disappear from the Terminal list, close the window.

Step 5. Close Terminal and open Console to inspect your drive errors.

Step 6. Click 'Errors and Faults' to check if there are any errors.

Step 7. Reconnect your USB flash drive back to Mac, if no error shows up, your USB flash drive is safe.

Fix 8. Save data and reformat the not showing USB drive

Disk reformatting basically solves many hard drive issues, including the not showing up USB, particularly the time when you are able to see the USB icon but files are not showing. USB drive showing empty makes no sense, so you have to reformat the disk and make it usable again.

Note that reformatting will erase data. As long as the data matters, you need to follow the standard procedure to ensure zero data loss.

Step 4. Finish the necessary information (name, format, and scheme) to format the USB flash drive.

Fix 9. Update your macOS and firmware

Did your Mac's OS keep updating all the time? Chances are that your Mac won't recognize a USB drive, especially after a macOS update. This time, take a close look at the settings whether your Mac is up-to-date. Equally, firmware updates address a variety of hardware issues and the functionality of the USB ports could well be one of them. So, keep your software and firmware up to date will likely make the USB drive show up as normal again.

Fix 10. Send the USB drive to a repair center

Nowadays even the branded USB flash drives are not expensive. If you've tried all the suggested troubleshooting methods, the USB drive is still not showing up on Mac, you have to accept the truth that it's severely damaged and beyond your ability to repair it.

Mac won't recognize a badly damaged flash drive or external hard drive since there is no way to show it up, even temporarily, which makes the data recovery difficult. The last chance for you to rescue data is to send the broken USB drive to a specialized data recovery service center nearby, and let the professionals try their best. You need to prepare for the manual data recovery cost, which is noticeably higher than the software data recovery. Hence, always try the cost-effective plan of using EaseUS Data Recovery Wizard to scan the USB drive for the first attempt.

Step 1. Correctly connect your USB flash drive to your Mac. Launch EaseUS Data Recovery Wizard for Mac. Start selecting the flash drive and click 'Scan' to let the software search lost files on it.

Step 2. After a quick scan and deep scan, all files will be presented in the left panel in the scan results.

Step 3. Select files you want to recover and click the 'Recover Now' button. Don't save the recoverable files to the USB drive itself in case of data overwriting.

Formatting VS Erasing (Is formatting or erasing permanent data deleting?)

Formatting, is to make a media a new place for data storage that you may change its file system while you format it. Formatted drive data would be marked as available for new data to take its space.

There are three levels of formatting

  1. quick format (no disk error checking and repairing)
  2. full format (includes repairing bad blocks)
  3. low-level format (it could only be performed by professional low level format tool, which is usually shorten the life of device)

Erasing, is to remove information on your device, which is more simplier than formatting, however it is not true wiping out all the information since erased files could be restored with help of free data recovery software.

Well, the truth is data could also be destoryed if you continue using your device after the formatting or the erasing and saved a huge number of files. If no data was saved to formatted/erased media, data could still be restored with professional tools.
