Hey guys, I've got a Western Digital Passport 320gb external drive (one of these:) Which has stopped working - when plugged in, the LED illuminates, the drive spins, and is recognised by the computer, but nothing comes up in terms of visible folders. Are there any 'free' software packages that might be able to help (on mac or windows), or if not - does anyone know any suitable data recovery specialists that can sort it, but won't charge hundreds! Thanks, Mike.
