I have just installed a new server and am running windows 2003 server. I copied all the files from my old server to an external hard drive and am now trying to copy them to the new server. I keep getting an error saying "cannot copy file:cannot read from the source file or disk" . It only happens when I try to copy the larger folders - approx 150 MB or more. I can copy smaller files just fine. Any ideas? Help Please.
