Hi, been having a problem with one of my USB drives when trying to copy folders over. I get a error code (Error code-36) saying it can't complete. If I copy over the contents of each folder it will do it but not if I try to drag and drop the whole thing. Reformatted my USB drive but still getting the same. Seems to only effect folders I've recently created as old ones will copy fine. Any ideas on things to check?
