Hi, I recently brought a sandisk extreme CF card 64GB with 120MB/s speed. After shooting about 1.2K plus photos .. the speed for the card became slow and I lost shot that was not capture on the card. It also fail to read some of my photos in the card. What I did was i manage to copy all the photo that it can read to the SD card and i reformat the card. In doing that I lost about 400+ photos which the camera cannot read. After that it was working fine, until i took about another 600 to 700 photos. when I was transfering into the computer, i lost about another 50+ photo due to JPG file corrupt. Does anyone have any of this issue on the new extreme CF card? It is really heartbreaking when you lost so many pictures..
I have the same problem as well.
I bought the 32MB and lost about 40 photos.
Seems that the new speed CF has reliability issue
