I needed to copy an entire hard drive without relying on the Windows interface, or I would be waiting a couple days. Instead, using the command line in Windows sped things up.
I know how to copy things in linux, cp src dst is the simplest syntax. In Windows of course, nothing is that easy. Windows does not use cp and I wanted a fool proof solution. Robocopy has been an ever favorite, but I never really understood all the switches, I wanted a prebaked solution. A quick google found me an excellent Serverfault article about it.
One answer suggested this:
xcopy source destination /E /C /H /R /K /O /Y
Which would do these things:
The command above will copy source to destination, files and directories (including empty ones), will not stop on error, will copy hidden and system files, will overwrite read only files, will preserve attributes and ownership/ACL information, and will suppress the prompting for overwrite existing destination files.
All those switches to just replicate what cp does. My files copied as quickly as they could, probably faster than they would have if I had used the Windows copy interface.
