When using removable media on a Linux Mint computer, you will have to “eject” the removable devices from your computer. This term is a holdout from the old days of floppy disks when you would have to press a physical button to eject the disk from the drive. This holds true with optical discs, which still need to be physically ejected.
It is still a good idea to eject your USB drives before physically unplugging them from your Linux Mint computer.
Why not just yank out the USB flash drives and hard drives? When you connect a USB storage device to your computer, Linux Mint mounts the device as part of the filesystem. When you eject the device, Linux Mint first checks to make sure there are no open files or folders on the device, and then unmounts it from the system. By simply unplugging the device, you risk the chance of interrupting Linux Mint in the middle of writing to or reading from a file, which can cause data loss. It is better and safer to eject the device first. Fortunately, this doesn’t take much time at all.
There are two ways to eject devices. The first is to find the device’s icon on the Desktop and right-click on it. Select “Eject” or “Unmount” from the menu that appears (the actual term may vary by device) and Linux Mint will eject the device, allowing you to remove it safely. The second is to open a Nemo file manager window and look for the device you want to eject under the Devices heading in the left-hand pane. Next to each ejectable device you will see a small arrow. Click on the arrow button, and Linux Mint will eject the device, allowing you to remove it safely.
