Windows Explorer is notorious for not working well when it's
performing operations which are being done through a wedged-in
layer designed to "trick" it into thinking it's dealing with
just another drive. All of the "make my Treo look like a
thumbdrive" software is doing at least two layers of that
sort of indirection.

Windows Explorer is *also* notorious for failing when asked
to perform an operation involving a very large number of files
or a very large amount of data.

Those other apps are probably trying to use the same methods
that Windows Explorer does, and making the same wrong assumptions.

If you have to do it this way, I'd suggest using a command-line
application such as xxcopy, which has a lot more error-checking
(and a lot more patience).


Having said all that, the functionality you're looking for
is a good idea, and I hope someone builds a conduit that would
work that way as part of the regular sync, if there isn't one
already.

P.S. Also try setting the properties panel of a thumb drive
mapping - there's a checkbox for "optimize for quick removal"
vs. something else I forget; that might fix one of the errors
you mention.

Using Windows Explorer to copy a huge number of files 
from one pretend USB device to another at the *same time*
...that's some serious optimism.  :)
