I dont think it makes much sense adding more complexity for just
for a single case. As Theodore already pointed out, you've got
a problem in the usb storage and/or the (OS-side) filesystem,
so that would be the first place to look at.

Another way would be coding an own overlaying filesystem (via
9P or FUSE) to handle your desired sync magic. 

BTW: I'm working on MC based on my libmvfs (a small userland
VFS library) - this is also a place where such an fs could be 
plugged in.
