Mounting a disk makes it accessible by the system. Unmounting a disk prevents your system from accessing any data and there is no risk of your disk getting disconnected during data transfer. Hence, before you remove your external storage device like a USB flash drive, you should first unmount it to avoid data corruption.
Once your drive is unmounted, other storage devices can access it. Note that the file system will be inaccessible during regular reads and writes.
