Do you use teracopy? It's notorious for causing that kind of error messages when operating on any NTFS formated volume.
Also, on such a volume, it's much slower than the normal Windows process.
If Teracopy is installed, UNINSTALL it.

It's not a machine error and neither is it a software error - it's a user error...
You are trying to paste something into a place that does not understand what the something is - and if the software permitted the paste to go ahead the destination file would become corrupt and unusable - your intended action would violate the integrity of the file.
