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.
