5DM2 Not Working With 64GB CF and ML
« on: September 11, 2013, 07:14:32 AM »
Hi all,

     I have a 5D Mark II. I put the newest nightly build on my Komputerbay 64GB 1000x CF. It kept giving me problems stating that "Fonts.DAT" wasn't found. Finally, it stops saying that when inserting into the camera. I inserted in the camera and recorded a regular .h264 video. Then took a couple pictures. I hit playback and the images and video was corrupt. The images were fuzzy with a big banner that said they are corrupt and the video would play like the first frame or couple frames and loop for the remaining part of the video. Now when I try to turn it on with ML on the card, the playback, info, trash can, live view, and menu buttons do nothing.

     I put the same files on my Komputerbay 32GB 600x and it works perfectly.

     I bought a new Komputerbay 64GB 1000x and I put it in the camera. It won't format. It just refuses to! What do I do?

PS: If I take out the card it works as normal.

One other thing to note is that when I insert the card that won't format in the camera actually in the camera, the camera waits for a while and displays busy on the side lcd. Yes, this card is visible on my mac and will supposedly format it, but the 5D2 won't read it.

Hi, did you figure it out what happened?

I have a similar issue. I had ML installed in a 16gb 1000x card, once day it gave me problems, after weeks it no longer recognised the card. I bought a new 16gb lexar 1000x card but the same, it won eve let me use it.

But if I use an 800x 8gb lexar it works without problems...

I think I have the same problem as you or almost the same.
