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. -- Julian Stacey. Consultant Unix Net & Sys.
