So I was out tapin' last night with my AT853s and JB3 and the opener goes just fine. Then I get through the first set and I go to push stop and I get the unable to save message. I've heard of this happening before (never been there) and I know that if it is unable to write the file everything is lost. So I say to myself "ohh shit" and chide myself for not daisy chaining a backup in and then I say to myself, "okay, well at least you'll catch the second set". So I try to start a new recording and it gives me some bullshit about insufficient space for the recording (those wasn't the exact error message but you get the gist). I pull the battery, repeat the process and get the same shit. Here's the rub. I just reformatted my JB3 before the outing so it was clean and should have been no problem. So I come home all pissed, and say I'll get to the bottom of it in the morning. So here I am, sitting at my desk and my JB3 works again (I did like 5 test recordings sequentially and it saved each one appropriately). So what is up here guys? Can anyone shed some light on my situation. Honestly, I would have been much happier if I had needed to reformat and reinstall the firmware then having to run around with a tempermental recording rig.
