I had some strangeness with my PCM-M10 las night and did a quick search, but didn't see any posts with this issue.
I was recording a band with CAFS-Omnis > PCM-M10 so I was not looking at the recorder during the show. After the show when I powered off the recorder, I noticed that the upper 1/3 - 1/2 of the screen didn't look right...it was mirror image, dark with light text. By the time I noticed this, I had already slid the power switch so I didn't get a good view of the exact display issue, although I did note that it took longer than usual to power off.
While riding home, I decided to play back from the PCM-M10. The recording was about 2 hours long. I fast forwarded through the 1st 30 min which was before the band started. The show sounded great, but then around the 90 min mark, the recording began to sound funny. It sounded almost like it was skipping. This 'skipping' continues for the rest of the recording. When I got home, I loaded into Audacity to look at the waveform and it does not have breaks. I also listened closer and essentially it sounds like the recording is just missing segments of maybe 1/2 second or so. The sound before and after the gap are seemlessly (on the waveform) blended together.
Has anyone else seen this? I am using a Ridata 8 GB card and recording to the card before internal memory. I have been using the card for probably 9-12 months without any problems with maybe 2-4 shows a month. I had reformatted the card (via USB cable) on Saturday. I then recorded a couple sets on Saturday night. I hadn't had a chance to process those sets before last night so I did not format before this show. The two sets from Saturday do not exhibit this problem.
I suppose I can think of a few possibilities.
1. My card is dying.
2. The recorder got too hot (I normally run open) or otherwise randomly glitched. (I did not notice the recorder as being particularly hot when I powered it down.)
3. The recorder is dying.
Any suggestions?
