I am planning to get myself an external HDD. Is there any offering that you may be aware of with an option to open the contents in a default read-only mode (may be firmware based or physical switch), allowing write operations only after authenticating (may be like a password or physical switch), without having to install any driver/software in each computer I plug this into? Does encrypting give me the same facility? This is because I don't want to regret after plugging my HDD to an unknown PC possibly infected when I just want some data copied from disk to that PC. Thanks!

Doing a quick google search has lead me to this:
