Unfortunately I cannot copy files onto the digital camera. It mounts as a
read-only device. However, I copied the same file twice from the camera to the
file system and compared: files differ.
I created hexdumps of the two files and compared those. It appears that there
are simply a few single bit errors. See attached file with the diff of the two
hexdumps.
Here is the log of what I did:
