How do you find a lost flash drive in your house? The last place I saw it was on a glass table. I looked everywhere. This is an emergency!
If you get really desperate, you could literally scan every inch back and forth throughout your house back and forth and you'll be bound to find it if it's there
Look in bags! Maybe your backpack? I lost mine once and bought a new one only to realize that I had put it inside a small pouch in my backpack .-. lol
