I had an r16 for 9 years before I had to get a new one. Now all of a sudden I'm starting to get "file access errors messages occasionally and I can't complete that recording because it won't let me that file past the error message. Manual says to exit, which I did, no good. Turned off power and turned back on. All tracks are saved to that point, but I just can't go further. I was really tempted to get an aural interface and DAW like most of the rest of the world, but I didnt' want to lose all of those files i had on the SD cards, etc. By the way I also tried deleting files to give more space to no avail. any ideas?
