Using Cyberduck (Version 2.5.5 (1971) sorry for not being up-to-date) I
transfered two sets of files from a Linux machine to my Mac. Both sets
consisted of 900 .tga image files each 2.6MB in size (representing frames
of HDTV 720p) for a total transfer of 2.3GB. The transfers were initiated
by dragging a folder from the server (in Cyberduck's window) onto my
desktop. While later processing these sequences in QuickTime I got errors
("Failed (-8969)") which turned out to be because two of the frame images
were incomplete.
I wondered why Cyberduck had given me no error or warning about the
incomplete files. I fixed the problem by manually dragging over
replacements for the two bad files. These files transfered as expected,
so the original data seemed to be fine. I was then able to process my
animation data in QT.
But I was REALLY surprised when the second animation sequence had the same
problem, and it turns out, on the same two frame numbers! The content of
the two video sequences were different, yet frames 384 and 768 of BOTH
sequences were only partially transferred by Cyberduck. Note that these
frame numbers are related by a factor of 2, suggesting a bug that
manifests itself every 384 files, or roughly every gigabyte?
Here is a view of one of the two folders, sorted by file size, showing the
two incompete files at the top:
