I had backed-up the images taken from the card, onto the DVD, and worked on one or two , in PS, then Saved into My Pictures, and a USB drive stick. Later, I discovered the DVD announced itself as "NO DATA" . HOW, and WHY I do not know. It's a mystery.
Was it a Rewritable DVD, if so accidentally hitting delete while the disc drive was high lighted could have done it.
