Dear all, I've asked this question last year in September supposingly as well. Then my SD card, which had been previously in a card reader, which wasn't the best, couldn't be read anymore - it showed, in both camera and reader, that it needs to be formatted. Now I have the same problem with a card bought last month, 5 years guarantee, from Hamburg, Germany, the department store Karstadt. The name is Formel 1. I found on CHIP.de that PhotoRec would read the images, and was happy. I bought a new card reader (ACME) for this. However, 0 file recovery. Any ideas? The camera is a Nikon D3000, bought February 2011, and the Nikon seller sais that I should use compatible cards, like SanDisk and Lexar. And that then at least it will not happen again. But with the FujiFilm (XD cards) I never had problems, over many years. thank you and kind regards Maria PS: for a photo salon no image I took with the Nikon was accepted, but FujiFilm ones yes (yes, FujiFilm is digital) - maybe I should get back to the old camera?
