I have done the [almost] the same thing! (I had a little help )

Situation:

-- Start a 9 hour car trip to visit friends in NYC, carrying 1 passenger.
-- Get a HD not found message for the first time (on this unit).
-- Stop immediately at a home depot, buy allen wrenches.
-- Coach my girlfriend, who is entirely non-technical, through the entire (temporary) repair in no more than 20 minutes. (while speeding!)

I'll have to admit, though, your repair was quite an impressive (if not dangerous) feat.
