Only very recent i have a problem, i shoot 100 pictures load them into aperture, at least 8 of the 100 raw images have pink blue or white bands across the image or half the picture is covered or one corner. you can just about see the photo behind the colours, if i send them to photoshop Cs5 and look through the raw images the ones that were highlighted in aperture sometimes are ok in photoshop, the ones that are not ok might be fine in aperture. is this a software problem or is it my computer.

Sounds like a camera issue to me. Does the same thing happen when you change memory cards? Can you upload an example image?
the same thing happens with a brand new card
What do they look like on your camera screen?
They look perfect on the camera screen, even the thumbnail images look ok on the computer, it appears when i open them up?
If they are OK on your camera, have you tried opening them in the camera manufacturer's own software?
Looks like a corrupt file. Often a single corrupted file can have a knock on effect on other images shot afterwards on the same card. I would try and salvage what you can and then format the card in-camera. Try copying a load of images from your computer hard drive to the card to see if they're written to the card without errors. Also try taking several test shots and check to see if they've come out correctly.
What brand of card is it? If it's been purchased from E-bay, it's possible it could be an inferior, fake card. Not that it couldn't happen to a decent make if you're unfortunate enough.
The images are displaying fine on your camera, because those are just jpeg previews, it's the actual Raw file itself which is probably corrupt.
Do you format your cards when you have finished downloading them or do you delete them? You may have a faulty card. Have you tried other cards?
i used a brand new one the other day and had 6 bad pics out of 50, ive always deleted pictures in the camera, now i will format the card every time i use it
I think that some of the files are partly corrupt so when you view them on the camera it will show you the embedded jpeg which is a small part of the file, when you view them in Photoshop it will ignore the embedded jpeg and import the raw file and problems will show up. Aperture is a funny one, it could be that it uses the embedded jpeg for fast preview of files but doesn't read the raw data until you fully open one of the images in which case you should get the same result as Photoshop from the same file but only when you open it fully as if to work on it.
There's software available, for Windows and possibly for OSX, that can recover all of the embedded jpegs and save them as separate files - jpegs are better than no files at all.

A different card this time? If so that would be pretty unlucky to have two duff cards, sure there are plenty of fake cards about but they tend to be real generic memory cards with stickers claiming they are a faster card and better brand than they really are.
For it to happen to two cards I think there may be a problem with your camera, perhaps there's electromagnetic interference while camera is writing to the card (eg from a mobile in a top pocket).

Good advise indeed, but I have never connected my camera to a PC
Take the card out and use a card reader
This happened to me, and it was a card problem, sometimes OK then like yours, new card sorted problem for ME...Len
You have six variables that could be causing the problem, Camera, memory card, card reader , computer, import software and finally imaging software. You need to isolate the problem and have already ruled out the memory card so you are now down to five. So if possible try another computer if fault still apparent the you can suspect the camera or card reader if all ok then it's the computer or software.... you get the idea, it's just a case of elimination and removing elements from the equation to find the culprit.
Best of luck..... Trev
