I had been having problems with my Kodak easy share camera and dock, I could not transfer pictures from the camera, I needed the pictures on the camera quite urgently, so I purchased a flash memory card reader.
I plugged it in this morning, and the drive showed up in My Computer, on accessing the drive it appeared to be empty.
I used the microsoft scanner and camera wizard to access the drive and the pictures showed up, but when I tried to copy them I was told the file could not be copied.
To check card: put memory card back in your camera and see if you can view the pictures on your camera. Are you being careful with the little switch on the card 'Lock/Unlock'? Make sure it is fully in the UNlock position.
