I just upgraded to Ubuntu 16.04 LTS, and wanted to backup my files (i know, i did it wayyy after i was supposed to, judge me if you want) but when i put my SD Card in, it wasn't recognized (i mean that it doesn't appear in the file explorer). The SD Card slot on my computer doesn't let the SD card go all the way in; that's the design, but i think this is what's causing this. Idk.

I'm using Ubuntu 16.04, and Dell Inspiron 20 Model 3048.

P.S. I'm using an SD Card adapter from PNY.
