I had my CF-card reader die on me a few times (ie, it suddenly stopped working: instead of being recognised, and then allowign me to access the CF card, it was "cycling", ie appearing/disappearing from windows). So I decided to do a backup using an USB cable.
- my PC had [historically] the EOS utility installed
- for personnal reasons (mostly: special workflow, and avoiding the clumsy download inteface) I wanted to just copy the files over, BYPASSING the EOS utility
- however, when plugging the USB cable between the 5d-ii and the PC, it only got recognised as the camera, and when exploring that I could see each image TWICE in JPEG (one with extension, the other without, but both JPEG, whereas I know that on the CF one is .JPG, and the other .CR2, larger and with more details). I tried however to copy both, each in separate directories (as they had the same name), but it really ended up as 2 identical files each time, as if it "hides" the raw and instead shows another instance of the associated JPEG file.
exemple: using a CF reader I would get IMG_0001.JPG and IMG_0001.CR2, the 2nd raw and much larger in details and size. Via cable I saw "IMG_0001" and "IMG_0001.JPG", both ending up as "IMG_0001.JPG" on my computer, and none the raw file...
How could I retrieve the .CR2 files? (if possible, without uninstalling the EOS utility! But still bypassing it... Ie, how to use a USB cable and access the files as if by a card reader?) (Should I boot on some linux boot CD and try from there?)
