I have a similar problem. Hope you can help.
2 identical HVX-200E, same firmware, age etc. One shots close and the other shots total.
I card reads perfectly and the other one says “ERROOR no date” after attempting to transfer. The thumb, timecode and everything seems OK, its just when it tries to transfer from this one card.
The cards were not write protected when I copied the content to the externaldrive where copies of both cards are sitting in separate folder.
thanks in advance
Bobby
