I think you are right. I think it must be the cable or the NEXTO communication with the PC. I'm glad you solved your problem.
My similar problem is not solved yet.
Yesterday I was shooting about 300 pictures. Exactly 4 pictures were wrong. 4 Corrupted NEFs. Like my previous bad pictures : On the camera the NEF seems to be ok, I can zoom in and out and i can see the picture correctly on the camera screen. But if I convert it to jpg on the camera the jpg gets corrupted as yours. If I try to open in CaptureNX2 the program crashes.
I will try to give you more data: - Like Brian said, previous to the shots, I formatted the card with the D300. - The card was empty so I didn't delete any of the pictures to save space. - I detected the issue was on some (not all) rapid sequence shots. First shot, less than 1 second, another shot. 1st shot corrupted. 2nd shot ok. - The card used is a 8GB Kingston SDHC class 4. I use a 15$ SDHC to CF Adapter purchased on ebay.
I think the card is ok. I have used it a lot of times with my old d3000. But I am beginning to think if there is a problem with the SD-CF adapter. I hope the shutter and the buffer of the camera are both ok.
Do you think the sd-cf adapter could be the problem? Thank you in advance for your responses.
