Ssd drive mounting in terminal

Trying to mount ssd drive viva usb on raspi4 getting errors research on you tube and google cant find anything to help with this error // mount: /dev/sda1: can't find in /etc/fstab.

mount command requires both a device and a mount point (which needs to exist). The mount point is a directory, and you need to ensure the permissions are set according to what you want to do
