Only a guess...
You have a problem with that SD card. Not all of them work and I've seen similar things happen. Part of the problem is that it takes less current to read than it does to write. Writing can take a lot of current on some cards, causing volt drop and causing the card to shut down. Once that happens it's flagged as being removed. Sometimes you can add a filter, a low value resistor and an electrolytic capacitor in the VCC line to the card. That doesn't always fix it (been there, done that). The answer is generally a new card from a reputable manufacturer.
