What Does SD Card Mount or Unmount Mean?

Well, the mounted & unmounted phenomenon isn’t new to SD users, but it’s quite common.

Still, there are a few users who get confused between the “mounted” or “unmounted” word. Therefore, below I’ve discussed both of them very clearly:

SD Card Mounted: A mounted SD card refers to the process of connecting the SD card to a digital device (PC, Android, etc.) and making its contents accessible to the device’s operating system. On the other hand, we can say, the operating system recognizes it and allows you to use it.

SD Card Unmounted: An unmounted SD card simply means that the card used in a digital device (PC, Android, camera, etc.) has been disconnected from the device without being properly ejected. And it’s no longer connected to a digital device to store or transfer data.
