so that's the good news. the bad news came earlier in the night. For the first time since using the MicroTrack, I lost a recording. for the opening act, I was running a 1 gig regular Sandisk CF card (not Ultra II or III or whatever, just a plain Sandisk). I've used this card many times for opening acts, but in the past, I've always run at 16 bit from the V3 (via S/PDIF) for the opener, giving me an hour and a half of recording time. well these opening acts for Club d'Elf usually only run 45 minutes or so, so I thought I'd give 24/48 a whirl for the opener as well. Also, Scott and Rob were both recording as well, so I knew that if anything went wrong, I could just get a copy from them. this recording mysteriously stopped at 29:24.
That sounds suspiciously like the S/PDIF cable came loose or some other problem on whatever is sending into the S/PDIF in. If this happens, the MicroTrack's counter will stop and the recorder will just sit there waiting for the signal again (try pulling the cable during a recording to see what I mean).
definitely not. the cable was nice and snug the whole time, and the bag definitely didn't get jostled around or anything. and I really doubt that it's a problem from the V3

actually, at the end of the set, I pressed the "rec" button to stop and save, not realizing that it had stopped at 29 minutes. so then, it started a new file. so instead of the "saving file" screen that I was expecting, I saw a second file being recorded. (which I then stopped a few seconds later).
I didn't have any time this past weekend to do any tests, so I still haven't really figured it out...
