I changed the batteries before you ask, and in fact, that's where the pain began... Happily cruising through the universe during a Frontier : Elite 2 sesh on Outcast, batteries died, ho hum, thinks I, lifts my heavy arse off the sofa, gets fresh batteries, bung them in, turn on my GP2X and erm... nothing. Turn off, then on again. Nothing. Try again, wait 60 seconds - nada. Turn off, pull out SD card, put it in card reader on laptop, and the laptop says - "Uhm, what SD card are you talking about? I can't see anything." I'm very surprised by my talking laptop, but then I remember that my soul is weeping for I know not what to do to salvage something - anything - from this ungodly mess. Ideas? I have an unrecognizable SD card for no apparent reason. Because its unrecognizable, I can't get at it to make it recognizable. So its still unrecognizable... and so on.
