I'm getting this problem when transferring large folders full of photos from my hard disk to a USB 80MB connected hard drive. The copying works OK to begin with and then grinds to a halt with error msg: Cannot create or replace **** Cannot find the specified file. Make sure you specify the correct path and file name. A message pops up on the tool bar entitled Windows - delayed write failed.
Yesterday it was a similar problem with the error msg: Cannot copy ****. The path is too deep.
NB I am not an IT professional!
