I work at a production company and one of my shooters reformatted and recorded over a XQD card that had not been backed up yet. Is there anyway to attempt to recover the footage? Years ago, I used RED UNDEAD and it worked ok.
I think if the card has been reformatted and overwritten I think you have a problem. A colleague mentioned this software as working on XQD cards but I have no personal experience with it so for what it's worth here's the link. $40 worth.
I just had a very positive experience with Data Recovery Wizard: my card was corrupted and couldn't be read, this 80eur software gave me back all my clips from a two-day eight-people shoot.
