Hi

I got this MMC card from a client. She said that nothing happened to it, but all the photos are missing.

When I checked the card, it's well detected and seems to work fine. Passed R-Studio on it and no files found :shock:

I opened it with Winhex and it's all 0000 and FFFFF as you can see in the pictures.

Is there any change to get the files out? What could cause this??

Thanks

I know depending on the brand and model of camera they have their own different ways of doing things when you format them. Most I have seen low level format the card with their own specific patterns. That's the only thing I can figure from this. We see it all the time "I didn't do anything to it" but walk them through the process and then they remember they formatted it.

Just my guess.

So this suggests a LL format of the card, right?

Change a single byte in some sector, then remove power from card and connect again, check if byte remains changed. If yes, data is lost. If no, then it possibly some controller failure.
