How to Fix ‘External Drive Not Showing Up’ Issue on Mac – Guide
Most of the time, when you plug an external hard drive into your Mac’s USB port, you’ll soon see it mounted on your desktop. Apple likes to make sure they’re easy to find, so they also show up in the Finder in the left column under Places.
However, sometimes an external hard drive does not show up. It’s annoying, especially when you need to transfer something at that moment. Also, there may be a risk that the data on the external USB pen, hard disk or flash drive will be corrupted, meaning you cannot transfer what you need between devices.
edit your preferences
If this isn’t the first time you’ve been using an external hard drive and you’re having this problem, it probably won’t be a problem for you. However, you can still check your preferences – just in case. Your settings may not be set to display external hard drives on your desktop. To fix this, go to the Finder and click on the Finder button in the menu bar at the top of the screen. Follow Preferences → General → Show these items on the desktop. Be sure to check the boxes next to External drives and Hard drives. Then go to the sidebar and also check hard drives and external drives.
Make sure your cable has enough power
Some hard drives require more power supply than others, different types and brands of cables provide more or less power. Typically, a device requires up at 500 mA, which can be supplied by a USB 1.0 or 2.0 standard. However, if the hard drive needs stronger power output, it may run slower than expected or not connect at all. Make sure the USB cable is providing enough power to the hard drive and, if necessary, switch to a more powerful connector or a different USB port on your Mac. You can also use an external power supply or even a USB hub with Own feed – Adding your feed to your Mac’s feed may solve the problem. Don’t forget to have your Mac connected to the charger.
Try other devices for power supply
If you find that it doesn’t matter what type of cable you use, the hard drive is still not showing up, the problem could be with your Mac hardware. Try using another Mac or Windows device – if it only works on a PC, it’s likely that your hardware isn’t formatted to start up on a MacOS device.
Use Terminal
For average users, the Terminal app is a last-resort solution because they tend to find it complicated. However, it is almost always effective and not too bad if you carefully follow the steps:
If you are running MacOS Mojave or Catalina, you may encounter the “Operation not allowed” error when entering a Terminal command. This is not a software bug – it is due to additional System Integrity Protection security measures that Apple has introduced in the latest versions of the operating system. It blocks certain areas of the system and only eases the block during updates.
To fix this error, you need to grant Terminal full disk access
