Well, the SD Card is perfect, it's not faulty. I tried using my Tablet's SD Card, but no luck. I know it worked in the laptop, because I once transferred music onto it. I tried using it in another laptop, and it worked.
I recently got a drone with a MicroSD to USB adapter which was included with it, but it didn't work. Well, long time ago, I got a SD Card with a Adapter so I can use a MicroSD Card with a SD Card reader. The Card's capacity is 1GB, but I don't remeber the card's model, but it was not bought from internet for almost free.
The computer acts like nothing was inserted into the SD Card Slot. But the Adapter I always use is not faulty. I tried the SD Card in my phone and it worked. The Device Manager detects it in SD Host Adapter section as SDA Standart Compilant SD Host Controller.
