sorry to hear that. If your card is now full, there would be no way to get the bridal prep footage anymore. The data has been all overwritten.,

Nicholas de Kock September 5th, 2010 02:28 PM

As Taky points out you can recover data easily if you format a card but once you record footage over a formatted card it's impossible. Sorry.

as noted, if you format a card or otherwise erase the data, you MAY be able to recover it, stick the card away until you get the chance to attempt recovery...

Once the 1's and 0's are overwritten, that's all she wrote, literally. I've heard that supposedly some "spooky" sorts of law enforcement entities can recover overwritten data, but I doubt it...

Im no expert at forensic technology and am not so sure about solid state tech... but when data is overwritten on a hard drive, it actually leaves behind a ghost image that is possible to recover.... which of course is a time consuming and expensive process. That is why when the government gets rid of a computer the hard drive must be overwritten with garbage data many times over to get rid of the ghost images and any hard drive with secret information is overwritten and then physically destroyed usually by shredding.

But I digress.... even with a good data recovery app, you may be able to get back bits and pieces, but I seriously doubt you will recover any amount usable footage.

Happened to me before too but lucky I didn't overwrite the card and was able to recover 99% of it. If you have overwritten it, as others have stated, it may not be possible.. but I would give it a shot anyway. Try Deep Scan using SandiskPro Rescue or something like that.

That was the sort of "spooky" type data recdovery I was talkiing about... I'm guessing magnetic media would actually have a "ghost" or the original material, possibly tape media... solid state... probably not.

I know top security stuff is supposed to be properly overwritten and destroyed, but with USB drives, I imaging "data security" is almost impossible nowadays - I read about those drives being a hot commodity in the bazzars in Iraq just outside the US zones...
