Copied my hd to an identical Seagate 160gb drive. All files are identical when viewed in my computer. The clone will not boot up when installed as master and the original drive removed. Message saye "a disk read error occurred". Symantec won't get back to me although they say an email comes in 2-3 days. It's a week. Should I get a boot up disc and try to work with it from that? Stumped!
