I also found a solution. It's working so far, but who knows if it will last. Anyay:
Download OnyX (freeware)
Open this app, and select the "maintenance" tab. In THAT window, you will be going to the "rebuild" section, but first, de-select all checkmarks under "permissions" and "scripts."
The under "rebuild, de-selct everything EXCEPT "appearance of folder's content." Leave it set for "this folder and all sub-folders."
You can now naviagte to all of your hard drives, and delete ALL .DS files. New, clean ones will be automatically and instantly generated.
Sadly, you cannot navigate to / clean an entire drive, it must be a folder. What I did was create temporary "hold" folders on each of my drives, into which i dumped the entire contents, then cleaned THAT folder with OnyX. I think you can also do everything at once by navigating to your master boot drive icon, then clicking on the "volumes" folder, (which oddly contains all drives connected to your Mac) but I haven't tried this yet.
Anyway, on my first two attempts at transferring huge collections of data, things went without a hitch, which is a minor miracle for me.
