I have been experiencing issues with ACR 6.7RC when downloading images from a CF card via a CF card reader (firewire). I have tried the following methods:
To rule out my MAC and CFreader I copied the CR2 files directly from the CF card via finder to another directory on the HDD and the process was very fast and completed without any errors.
To test further I have broken down the qty of images to convert to DNG; this seems to work when I convert up to 100 images at a time BUT the occasional DNG file can not be viewed as it appears corrupt; the original CR2 file is fine.
Interested to see if anyone else has any similar issues....
Yes, I see the same thing and have reported it.
