C100: Oh ****!!! I formatted a whole day of shooting and then recorded over it

[clint lealos]

I pray that someone here can help me. I committed the ultimate sin and formatted a very important card and recorded over it to make matters worse. Has anyone ever done this and found a proven solution? There are tons of recovery software sites, but I'm looking for something tested and proven if possible. Thanks in advance.

There are many utilities that can recover data after formatting but you've just learned an expensive lesson if you recorded over the original files. The data is gone.

Yeah I've heard of people recovering data after they formatted but not after formatting and recording over it.

This is why I run twin 64GB cards. When in doubt just keep recording and sort it out later.

You can try Sandisk Rescue Pro. I think it's free if you have a Sandisk card. I've used it before to recover stuff from SD cards, but never after overwriting the card so I'm not sure how much luck you'll have. Did you record over the entire card after formatting? A quick format of the card (as opposed to low-level format) will just wipe the card's directory and leave the data basically intact on the card. The data will sit there and can potentially be recovered until it is written over.

Sorry to hear this Clint. I really feel for you, but I wouldn't waste your time trying to recover the files. After format and record they are most certainly gone. Even if there are a few fragments, due to the nature of video data, they will probably be unusable.

I was the Gaffer on a feature a couple of years back where the Producer pi**ed the DIT off so much she left. The producer tried to do the job himself and ended up deleting half a days work. The amazing thing is the DOP ensured there were two recorded copies from camera and the producer managed to delete both!!!

We all make mistakes, but make sure you learn from this one!

Good luck.

Only recorded over the card partially. Any chance some of it is still there?

I'm not an expert on how the cards write info, but in general the way it works is that the data is all over the place and the directory tells you where to find the pieces. Formatting (quick format mode) just tells the directory that the whole card is now available to write over. At that point, recovery is known to be possible since all the parts of the clips are still there. Once you start writing new info however, you have mixed new bits in with the old bits, so even if you are able to recover or reconstruct the old directory info and find the locations of the old clips, there's a good chance that the new clips are going to have replaced some of the old data and made the old clips unusable. How much of the old clips survive is going to depend on how much you recorded after the format.
That's just a basic overview to give you an idea of what you're dealing with. Whether it is possible to recover some of the data or not I really don't know. Good luck.

If you only partly rewritten on the card then it's higly likely that some of your data can be recovered.
you could try this:

good luck.

There is indeed a chance, but no guarantee. try as many recovery tools as you can get your hands on

My go to in thais case would be sandisk rescue pro or reduce pro deluxe . Since you recorded on the card after formatting you may get some partial files back or none at all. Formatting a card by mistake is one of those sphincter moments , but not fatal if you don't follow the formatting action with recording on the card. If you use the formatted card to record new files, there is no easy way out, and you probably won't make that same mistake again...

A good practice to get into:
1) Have lots of cards. I have five 64 GB P2 cards(72 mins @ 60P / 170 @ 24P) for each of my VariCam's and six(more if you count the one's I have with my NanoFlash) 32 GB CF cards(80+ mins each) for my C300. SD cards are pretty cheap, relatively speaking. You should have at least 5-10, if not more.
2) Never format a 'shot' card the same day and until it has been backed up and verified that the data/footage is all there and intact. I don't even recommend deleting single clips 'to free up space' from a card while you're shooting, like some people do.

The Sandisk recovery software works great and is easy to use. Assuming that you didn't fill the card up again after formatting, you WILL be able to recover most of what hasn't actually been recorded over (I know because I've done this before). Good luck!
