hi. can anyone help? i have a ptr1 and i have been using it quite successfully for ages. i recorded some audio yesterday and when switching off the unit said, improper or damaged disc. i was very annoyed as the disk already has about 10 hours of audio recorded on it. is there any chance of recovering the audio or have i lost it. if i reload the disc i get the same message. hope someone can help, smile. steve.
