This also happens with my 40G Toshi in my ajr20 v1.26 after I upgraded from
the stock fujitsu. I have posted this problem before, but we seem like the
only ones that have it - I'm kind of glad its not just me.

I also found that my lap was the only workaround for this problem :-)

It also happens with the stock firmware - allthough I haven't used that for
ages.

I think maybe the physical attibutes of the vibrations are important.
However, I wouldn't rule out some sort of damage occured when we upgraded -
if we really are the only ones. I can shake it, tap it against stuff,
anything really - and it works fine - as soon as I put it in my car (on the
seat with me (I have no passenger seat)) and drive, it happens basically
every time. I have to put it on my nicely padded lap to use it in the car.
In fairness, the stock fujitsu drive did it too - to a lesser degree, but
only when I had it on the centre console, on the seat it was fine.

My old fujitsu has been sold now, but it would have been interesting to put
it back in and test it again, just to rule out any damage. Maybe you are
still in a position to do that?

Stu.
