Last weekend, I went to East Coast with relatives and take some pictures. Somehow I am now unable to retrieve the pictures in my SanDisk Extreme 4GB card. I had dropped my 4GB card in my office and someone may has step on it or ???
I input the SD card into the SanDisk card reader but it cannot detect the card. I have another 2GB Ultra which the card reader can detect and display the photos.
What are the possible reasons for card failure? Can I do a re-format of the SD card?
Appreciate some advice, thank you.
