Thanks so much, Karl. How do I write zeros to the SD card?
The audio is an interview. When I play it back RAW, I hear digital noise and then intermittent very high speed voice.

We recorded about 20-30 minutes of interview – lost power – then restarted and recorded 8 minutes of interview that is on the card. So, I’m assuming 8 minutes of the first interview was erased over.

Karl – could you or anyone else help me with restoring audio from a TASCAM DR-701D that lost power? I read through your methods, but it is way over my head. Any help is appreciated. I have an image file of the SD card.
