I was taking pictures on a Sandisk SDHC Card 4GB with an Olympus camera. Everything was going well, viewing pictures on the camera. Then one day I wanted to look at the pictures I had taken that day and for several pictures (not all of them) I got a message of format error. That day I stopped using that card.
Back home, I tried looking at the pictures on the computer but here also I could not see them (same ones I could not see on the camera - about 200 pictures out of 1,500.
I tried several recovery programs but the format issue was not corrected.
I also converting the files with the GMIP program, and graphic Converter but I also get messages saying that files are not images, or that markers are missing or incorrect.
I lloked at several forums but could not repair the files. Can somebody please help me?
