The read errors from the sectors ~800-10000 are normal for the Safedisk protection.
As krondike suggested, there is a program to help speed up the reading of these errors. It is called Daemon Tools - it is not the main function of Daemon Tools, but it is an added bonus. Goto the Daemon Tools website >>
www.daemon-tools.net << and read the online manual for instructions on how to use it's 'Fast Dump' feature.
