Copying a large file from portable hard drive to another in Windows results nothing

I'm trying to copy mu music-library (about 125gb) to another portable hard drive. However, When I try to do it, Windows' copy-alert just pops and then goes away. I've also tried to first copy them on C:\ without any progress. All of the drives are NTFS.

The Wiki page (en.wikipedia.org/wiki/Robocopy) provides a nice "Quick Start" under the common usage. In the external links, there are links to the Robocopy GUI and RichCopy as well as the Robocopy command line reference tool. But probably: robocopy C:\foo C:\bar /E Will copy Foo to Bar, recursively and including empty folders (as per the wiki) –  Dylan Yaga May 19 '10 at 16:11
