Don't F*ck With Terminal

Long story short, I was attempting to gain permissions to a DVD, which my computer recognizes as a "volume". (Nothing, illegal, btw.) I read up a bit (a very, little bit) on Terminal, and thought I'd try a few commands. Not only did I not gain access to this volume, but I accidentally permanently muted my system volume.

Fortunately, an hour of Googling lead me to a help discussion which suggested I re-set or zap the PRAM. Thankfully this worked, and I have vowed never to open the Terminal app again! (At least not until I educate myself on Unix commands.)

Consider yourself warned!!
