Well, I had my first error last sunday. I was rigged four channels; two as phantom, and 1&2 TRS input; @ 24.96
The day before I ran track at a rehearsal; no issue. The day of concert, as the house announcements were being made, I got a Write Error. I tried again, a couple of times, and got immediate errors. So, I jumped into the menu, and changed sampling to 24.48, and tried again. This time it stuck, and the recording went off without further issue, with only the boiler plate house announcement being missed. But, that was too close.
I had Erase Formatted (long format) the card prior to use, as I always do. So, it was a cleaned card.
I tried replicating the issue at home, and no go.
The card is a Sandisk 16gb Tascam approved model.
