I didn't mean to offer that as an actual workaround. I meant it as a demonstration that the SAME set of files can be transferred over to the unit if you use a different program to do it. A "sync" is, at it's heart, a "transfer" where only new or updated files are transferred (and some files may be deleted), so it seems significant to note that Windows Explorer can do this without problems.
I'm not saying that the file transfer protocol isn't related to this issue. I'm merely pointing out that this does not prevent Windows Explorer from successfully transferring the same files over, which indicates that the problem is not simply an issue with windows and the android transfer protocol. Once MC does the sync analysis and determines which files to delete and which to transfer over, isn't it primarily a transfer operation at this point? If so, and if Windows can natively transfer the files over, then what is MC doing differently such that the transfer doesn't work correctly?
Thanks,

ah i see what you're getting at- some users have been reporting missing files and incomplete syncs too i forgot.
SGS3 Easy UMS - Mount external microSD card as USB mass storage
http://forum.xda-developers.com/showthread.php?t=1711009unfortunately (or fortunately for some of you stock huggers ;-)) , this requires ROOT. that being said, there is might be a simple enough solution for Samsung / HTC users alike, but it requires a bit of research and "hacking" of your phone. truthfully, the devs at XDA and other android communities have made these rooting processes so painless and automated that the only risk is perhaps losing some apps worth of data in the switch. also, rooting does not require you to replace your whole UI or experience (that would be a custom ROM). simply gaining superuser access over your current install is like giving Administrator rights in Windows (which is a no brainer, no?)
if not..
the first thing you should definitely try is uninstalling the Samsung (or HTC is the other victim) sync software / drivers. they are junkware and can only complicate existing issues. next, disable USB debug > reboot. reinstall *just* the USB drivers if you can find them for your device (skip the sync manager bloatware, Kies, etc).
if anyone would like to give it a while id be more than happy to walk you safely through the process and back if it doesn't work... sucks to see you guys stuck with great phones that can't even do what iPods did ten years ago :-/
