Is this catching or what?
Last night (after several weeks of no problem use) I put the unit into the car and got the
No Hard Drive blues. I reinserted the unit several times without success.
When I got home I plugged it in and same thing. I did some reading on the BBS and
so decided to leave it til the morning then check for loose wires/connectors.

Tried it first thing, same again; jiggled with the connector, same thing.
Left it a couple of hours, now back to OK!
Put it in the car, again OK!

Will see how long it goes for now.
As per Bob's previous note, what should I do if it goes again?
