Yes, you can. Try sudo mount -oro /dev/<your usb drive partition> /mnt (for a more concrete example, assuming your USB drive comes up as /dev/sdc and has one partition, say /dev/sdc1): sudo mount -oro /dev/sdc1 /mnt Now if you are using a desktop environment, it will most probably mount things for you... but read/write. You can remount it read-only like so sudo mount -oro,remount /dev/sdc1 /mnt Perhaps your desktop environment has some knobs to do that. Here, I'll have to defer to more DE knowledgeable folks here.
