somewhat like the early USB ports that came out on some MOBO's, plug in too much and things stopped working. (say USB powered speakers, business card scanners)
the units would still accept commands ("scan!" "OK"... whir-ur-ur.u...)
the mobo still works, hopefully the scanning app doesn't lock it up, or if it does kill the OS hopefully they set the "Auto Reboot" option.

some of voyagers bits that collect data (photo's, RF waves, catch particles) do the work on their own, analyse then periodically feed back the results.

some updates were sent so some would run a bit slower/less often (they were already programmed to restart one by one because they knew further away power would be limited - probably added longer delays for that too.) and of course each sends back "X started OK" messages so if it fails during restart they will know where (apparently a while back a couple of things have failed and were taken out of the startup list).

So the unit wasn't fully offline (or would restart if it was) but from what I read (a while ago)
- designed to restart if it detected failure,
- upon restart first check (in some cases actually wait) for new commands before anything else
- the radio that receives commands is itself autonomous and has a buffer in case the core is down

of course takes a long time to see if it worked: Amazon "you're parcel has been sent" - takes a day or two before it arrives before you can confirm as complete, working, arrived at all.

NASA engineers are troubleshooting the problem, but it's slow going given Voyager 2's distance from Earth. With the probe 11.5 billion miles (18.5 billion kilometers) away, signals take 17 hours to travel one way and mission personnel must wait a total of 34 hours to see whether a command worked.

after many otherwise intelligent sounding suggestions that achieved nothing the nice folks at Technet said the only solution was to low level format my hard disk then reinstall my signature. Sadly, this still didn't fix the issue!
