1DX lock up?

Seems the 32 GB LEXAR 1000x is at least a small factor in the lockups! maybe that's why they are ON sale at BH.

Maybe. Card I/O is asynchronous, I wouldn't expect it to lock up the camera. When I saw the issue, the shutter got stuck open. Thus, I wonder if perhaps the new shutter mechanism might have some quirks that haven't been fully worked out, or if maybe some of them have manufacture defects.

Just acquired my 1DX and it had a BAD charger  first second right out of the box.  Pain full 2 batteries and no juice had to wait a few days to get the Camera store to help me. So yeah i can see them shipping a bum camera shameful 7000$ and  quirks, but its the market we live in.

Ran chkdsk /R /F from command prompt, and it found no errors. I also ran "error checking" (right click on drive, properties, tools, "error checking"). It, too, found no issues.

Hmm...

FYI flash is not like a hard drive and bad flash sectors are usually automatically remapped in the cf card's firmware so unless it's totally screwed a chkdsk /f /r /x won't help or let you know there's a problem. It's technically possible that it's still the card but i'd still suspect some camera bugs.

Thanks, exphose. I had also written a Perl script that copied large files to the card until it was filled. Didn't run into any issues with the card. That, of course, doesn't rule out weird interactions between the card and camera.

But I'll note that I've not seen the issue with the replacement 1DX I have (knock on wood) using the same cards I had before -- I've even filled them up during a shoot.
