I spent the morning shooting a bunch of old gear that I’m preparing to sell. Imagine my dismay when I opened the CF card and saw every single file looking like this (see above). At first I thought the camera was defective, but some troubleshooting revealed that I could display the images fine on my camera’s playback. So that appears to rule out both the camera and the card being defective. That pretty much left the card reader as the prime suspect.
However, further testing reveals that files pulled directly off the camera via usb cable also are corrupt. So now I’m back to thinking the problem might lie with a defective cf card after all. Anyone ever seen anything like this before? I’m using Canon 5dmkiii with Lexar Professional UDMA7 (1000x) 32GB CF card.
Unfortunately I have only one CF card (typically I use SD cards, which are working fine) so I can’t test with another CF card immediately.
*** Update 11/26: I purchased a UDMA7 compliant card reader, the Lexar Professional USB 3 reader, and it reads the card fine. Images open normally. So apparently the culprit is the card reader, not the camera, or the cable, or the card. I had understood that USB 2 cf card readers could be used with UDMA 7 cards, but apparently that’s not the case. For me, at least, the 1000x cards require an updated card reader to function properly.
