I was recording with a DR-10 and what I think happened is my subject pulled out the batteries instead of using the slider to turn off the recording. The result is I have two audio files that won't play. They do have size - 453mb and 336mb respectively They are both the second recording of the day, (002_230825 and 002_230826), but I think that's just coincidence. Both of their runtime shows as 0:00 I can tell by the data size that there are recordings there - I just can't play them. Any help would be greatly appreciated!
