Why not just use the -v flag of the copy command
Code:
D:\users\default>copy /?
Copies one or more files to another location.
COPY [/A | /B] source [/A | /B] [+ source [/A | /B] [+ ...]] [destination
[/A | /B]] [/V] [/N]
source Specifies the file or files to be copied.
/A Indicates an ASCII text file.
/B Indicates a binary file.
destination Specifies the directory and/or filename for the new file(s).
/V Verifies that new files are written correctly.
/N Uses short filename, if available, when copying a file with
non-8dot3 name.
/Z Copies networked files in restartable mode.
To append files, specify a single file for destination, but multiple files
for source (using wildcards or file1+file2+file3 format).
You'll need to ensure that the source file is big enough to fill the disk, as well.
