Another of the 4 USB sticks (each silverish plastic marked on
outside: "Sony Corporation D33021", with a yellow removable soft
plastic spot with black font, marked "2G", bought at the same time,
also went bad, (2nd on an XP, not a BSD, & also pulled apart during
extraction from computer). All 4 sticks were returned to dealer.

A passer by said he had also bought 3 x Sony 2G sticks from another
stall holder at the same Croydon (in Britain) computer fair, & all
3 of those had died too.  Our vendor was asked whether they were
actually Sony and said yes, but Sony had had problems with them and
sold them all off. His own supplier had bought loads of them and
some were OK but not all.

So there's bad Sony 2G sticks about (& note at least the stick that
pulled out of its plastic, worked OK first write).  I'm suprised
Sony didnt dump these 2Gig sticks in the crusher.  Maybe they thought
they had, & some criminals got involved & recovered them, or maybe
Sony haven't seen enough returns yet, & not pulled them.
