Once you haveyour memory card damaged, it is highly recommended to stop further operationson the memory card (e.g. taking new pictures, or delete, format the memorycard). Data recovery software like "Card Recovery" isable to recover the lost pictures in most cases.

First, you need to confirm your memory card can appear as a drive letter in"My Computer", which will allow recovery software to access andrecover the lost photos.

There are many card readersavailable in market (e.g. SanDisk and Kingston). You can buy one from Amazon orBest Buy.

Then, you may download and install Card Recovery to your computer. Launch itfrom Start Menu -> Programs -> Card Recovery. You select the drive letterof your memory card, and destination folder for save the recovered files. Card Recoverywill scan your memory card and locate the recoverable pictures. The process isquick and easy. Usually it takes less than 15 minutes.
