My SD CARD is not working

[cluelesslumpy]

A notification pops ups on my phone saying that the SD card was removed even though I didn't, is this a hardware problem? I dropped my phone 2 days ago. But whenever I use my phone like watching vids that are located in my sd card it's fine but when left idle it says that the sd card is removed.

Probably yes this happened because you dropped your phone
