Hi Ive been using an external hard drive now for 2 yrs......recently it started to go missing on the my computer menu.....erraticaly cutting in with autoplay whenever it fancied......Now its missing all together and I cant find it anywhere.....Ive changed cables, changed usb port several times....any advice would be appreciated.......I will take it to a friends in 7 days or so, to check its still viable..........but any thoughts in the meantime gratefully accepted....Happy new year!!!!
