Originally posted by ricky I usually plug only the camera to the computer( which is a Mac) when I'm downloading photos, but it doesn't have any other problems with other devices like external Hard Drives. Also this problem starts when I had just cleaned the sensor with sensor swipe. I don't know if could be any connection with that issue considered that the camera works fine. Could be the cause some kind of corruption of the SD Card? Thank you.
Do you have any other computer in the house?
Have you tried and see if it works OK on the other ones? If you don't have another computer, could you try with a friend's computer?
I doubt is the camera to be honest....
Have you tried to use a different cable? Have you tried a different SD card!?
