CR2 files greater than 10 MB transferred over just fine. All of the files were over 10 MB in size but size is not the issue – many. What’s interesting is that only the occasional Canon raw file (.CR2) will fail with the Error code -36 message. Here is the error message when the Mac OS X file copy process encountered such a file: For clarity, Canon raw images from the S100 are characterized by the. When the copy process encountered such a raw file it stopped the copy process at that point. Everything copied fine except for the occasional Canon raw file. Things got interesting when I attempted to copy the existing folders contains my images from the internal hard drive on the MacBook Pro to the Firewire 800-attached Oyen Digital hard drive. The external disk drive was formatted with the Mac HFS+ file system, just like the disk in the MacBook Pro.
I recently purchased a portable external disk drive ( Oyen Digital 1TB Firewire /USB) for holding all of my camera images, which includes jpegs and raw data from both Canon and Nikon cameras. I’ve been shooting raw images for quite a while and archiving them in folders on my MacBook Pro (Mac OS X 10.6.8). Since I use Adobe Lightroom (4.1) as my image repository, having raw images provides a lot of flexibility for “developing” the final image, typically in jpeg format. A few months ago I purchased a Canon S100 which has the capability to shoot both jpeg and raw images.
