I'd buy a second hard disk and copy everything to it. Then store that second hard disk in a safe place. What else?
I have Windows 7 64-bit, IE 7 on an HP Pavilion HPE - h8 1010. I save many files on a Hitachi 2 TB external hard drive rather than on my desktop. I now simply want to save a copy of about 640 GB of those files in a safe place. I do not want to keep updating those files, just keep them in a safe place in case that external drive fails. (Save those files and remove them to store in a safe place away from the computer.) What is the best method to use?
