Camera memory card was accidentally formatted?

OK! Le me describe my problem briefly In fact, recently, I just re-installed my computer Windows 7 OS and carelessly forgot the plunged Canon camera during that process. And then, after that, the computer just can not read anything inside this camera. There was nothing shown on that camera memory card. So, I guessed, perhaps, I might have formatted this camera memory card intentionally when trying to re-install the OS. Do you have any idea to rescue my camera photos and videos back? Please, help me!


First, DO NOT use that memory card to take any more photos - this would likely overwrite your previous photos, if they still exist.


Second, assuming you are using an SD card, search the web for "SD card recovery" programs.  Pick one that you like and give it a try.  If the card was indeed formatted when you reinstalled Windows, you may not have any luck, but it's worth a try.


OK! As you guess, this memory card is possible to be formatted. But, as to your lost card data, no matter whether it is formatted or not, you can try data recovery software to see whether your lost card data is still recoverable.

Add no more new stuff on this memory card and also do not format it or anything else. Just insert it to your computer and download data recovery software to take chances.

After data recovery process, also remember to change another storage device to hold your restored stuffs in case of data recovery failures.
