I bought a new card reader and have tried to download images from Panasonic SDHC (8gb) card without success. The PC was unable to detect the removable disk, and when it is able to detect it I still could not transfer the pictures. I then tried to transfer images from my 2 other SD cards and the transfer worked perfectly.
Conclusion: Card reader ok; Panasonic SDHC memory card faulty.
However, just out of curiosity I tried downloading the Panasonic card images again using another spare card reader and the transfer worked smoothly!
So, to conclude that the Panasonic memory card is faulty is also not correct.
Has anyone in CS encountered a similar situation before, and if so, how did you resolve it? Would appreciate members help.
