How to copy files between two hard drives faster?

Does the speed increase again when you move the paging file back?

I haven't tried that yet, but I will. In the meantime I found some errors in the Event Viewer - more specifically, eventID 11 - which seem related to the USB drive. You're right, I should try putting the page file back fist, although this is not a welcome alternative - the copy (but not move) speed has increased rather dramatically after I moved the page file.

Well, I did recover my USB transfer rate by enabling write caching in Windows, so now it's much better although the pop-up copy Window freezes at the end while it waits for the remainder of the stuff to be written from RAM onto the USB drive.

It's still unclear for me why copy is so much faster than move between different partitions of the same drive though.
