I'm attempting to copy some large files from my camera (Canon EOS 500D) to my laptop, which is running 64 bit Ubuntu 9.04. I am using USB to connect the two devices.
For most files, it is simply a matter of Ctrl-C and Ctrl-V. I have done this successfully many times with both photos and small movies (eg. 180MB).
However, when I attempt to do this with very large files (eg. 3GB), the copy seems to start with a lot of activity both on the camera and laptop, but after 10 minutes or so the camera is automatically unmounted and the copy fails to complete.
I have read that this might be due to the device not mounting as a mass storage device, but I cannot see any obvious way for me to change this behavior.
Can anyone offer any direction here? I'll get a USB card reader if necessary, but I'd prefer to be able to just plug my camera in.
