My SD card is not showing up in Finder

I have a SD card that I put into my MacBook Pro. It then showed up in finder. I wanted to access it and I accidentally dragged the mounted card and now it's gone from Finder.

Taking out the card and inserting it again, didn't help. How can I find my SD card drive again?

In the Finder's sidebar, there should be a section called 'Devices'. Click on the one that's your computer's name and you should see the SD card. Drag it back to the sidebar.

In my case it did not show up because the name was blank. I use disk utility to name it.

I found that removing the SD card, then restarting, then putting the card back in after complete restart worked fine for me.

Make sure "Show External Disks" is enabled in Finder. Here's how:

Open Finder, Click on 'Finder' on the top bar and select preferences. 'This should bring up the Finder Preferences box. Under the first tab (General) make sure 'External disks' box is ticked. Under the third tab (Sidebar) 'Show these items in the sidebar' scroll down to 'Devices' and make sure the box next to 'External disks' is ticked (though this was probably selected by the first action)
