Cooked Hard drive replaced by another repairer who also indicated that all data was lost, on connecting up at home new hard drive also cooked. Took my tale of woe to Nick at Nerdcore in Hughesdale and with wonderful customer service he explained lots of things to me in terms I could understand, installed a new drive, retrieved all of my "lost" data and made me very happy. Well done Nick - it's good to find people who know what they are about.
