What Does Unmount SD Card Mean?
Unmounting an SD card means disconnecting it from your device without physically removing it. After you’ve dismounted it, the device won’t be able to read from the card without mounting it again.
While many users skip unmounting their SD cards and skip straight to physically removing them from the device, unmounting first is the proper way to remove a card without risking damage.
Unmounting isn’t always called by that name, however. Sometimes, the option will be listed as “eject,” but the terms mean the same thing.
Do I Need to Unmount an SD Card Before Removing It?
Unmounting might seem like an unnecessary step, but it can save you from a headache later. When you unmount the SD card before removing it, you ensure that any running operations such as file transfers are fully completed.
If you skip this step, and remove the SD card while it’s still doing something in the background, you can not only lose your recent actions but also corrupt the rest of the data on the card.
It only takes a moment to unmount your card before removing it, so it’s a good idea to make it part of your routine if you want to avoid losing your data.
How Do I Unmount an SD Card?
The way you unmount an SD card varies depending on your system. However, the methods are fairly similar across the board.

It’s as simple as that. Once you’ve done this, you can safely remove the card.
Unmount SD Card on Android
The method to unmount an SD card on Android may vary slightly from phone to phone, since each Android manufacturer makes slight changes to the OS. The basic idea should be the same across all of them, though.
