True, and not only that, USB jacks on PCs and laptops can develop problems.
I was running MC20 as a DVR on a spare laptop, and continually having problems. When I moved the external hard drive to my router (and thus recorded TV to it over the ethernet cable from the laptop to the router), all the problems went away.
If you do a web search, you'll find a lot of threads talking about USB going bad on motherboards...
