HI - I have a Nikon D70 and when I tried to transfer photos

This answer was rated:

HI - I have a Nikon D70 and when I tried to transfer photos from my camera to my mac (iPhoto) it shows 10 blank squares (so it knows there are 10 photos...) but the preview doesn't show up and when I click on transfer all it says "unrecognizable format" when I try to view the pics on my camera it shows "file does not contain image data" ? but I'm thinking there must be something there because it seems to know there are ten "photos" even though they show as blank squares... ?

Hello and welcome. How big are those files (individually) in MBytes?

I'm not sure - how can I tell?

You need to use The finder:

I am familiar with the finder but they aren't going to be on the finder if I can't transfer them right?

Ho i see, the pics you took with the camera show as black square on the camera. Those are picture that never leaved the camera and edited on a computer?

not exactly, no. I took the pics on the camera. I plugged it into the mac via usb port - waited for iPhoto to "see" them - it said I have 10 photos to upload and brought up 10 blank squares (normally the photo would be previewed in these squares) I tried ignoring the fact that they were blank and asked the computer to transfer all 10 and it says files are "unrecognizable format" . If I try to view them on the card while still inside the camera it just says "file does not contain image data" - which normally I would assume means there are not any photos but the fact that the mac is recognizing there are 10 files means there must be something on the card I think...

Ok, I researched this a bit and found this:
I don't think this is your problem as the camera say "file does not contain image data". A bad shutter or CCD would still give a valid image data (even if not what was intended to be took in photo). So it look like the camera internal card reader writer have a problem, or the card itself. Some corruption seem to have happened or a damage, or something dirty block proper electrical contact between he card and the camera.

So i would do a visual inspection of the card and contact, try another card and see if the problem still happen. If you have other pictures on that card that show fine, it might be recent file system corruption from the last 10 pictures. One thing is sure, forget about trying to get them to the computer if you can't even see them normally on the camera, this is the first problem to solve.

ok, maybe it is a corrupt card then - This happened last time I used this camera and card but I blamed myself because I thought it was because I had forgot to format it first - I definitely clicked on "format" this time before taking these photos and the same thing happened...


If the contact with the card is not optimal at all time (like a bended pin) the corruption have more chance to happen. Formating can often make previous corruption disappear (and all the file also) if the corruption was caused by a bad contact or a software glitch in the camera, that said it may not fix a card if the damage is with the material inside the card itself.

Another thing that can cause corruption is missing battery power at the same moment as a recording take place.

ok, but it sounds like a new card would be the first thing to try right?
