Flashing folder with question mark after being dropped
My Macbook fell from the table but I was able to turn it on and nothing seems damaged. A few days went by, I put my laptop to sleep and when I open it, I see the flashing folder with question mark. I was able to restart the laptop and it worked like normal except that this happens every now and then, maybe more often when I throw it on my bed. Should I be concerned and how do I fix this? Thank you.
