The code below gave me this error message

"Could not complete operations on some files and directories. See the Data property of the exceptions for more details"

Where do I find the Data property of the exceptions so I can troubleshoot what is causing this error?

Code
**********
directory_name = "robotic_surfing_vb 2008_scripts"
My.Computer.FileSystem.CopyDirectory("C:\" & directory_name, "T:\Backup\Laptop 3 - Dell D610 - All Data\" & Format(Now, "MMddyy") & "\" & directory_name, True)
