RWs are perfectly fine, although a thumb drive would be much easier. Or just backing up the important stuff
Thank for your response. I already use a separate harddrive to keep copies of all my major files, which I can connect to with either my PC or laptop and share information between them. The backup to which I refer is part of the Backup and Restore program that came included with both my computer and laptop. I got the laptop with Windows 7 almost a year prior to being forced to replace my 8yr old computer (which was still running Windows XP) due to corruption of major files on the harddrive which absolutely prevented rebooting the computer. Repairing the problem was way more expensive than buying a new computer, even though I still don't like Windows 7.
Anyhow, I guess I will find some thumbdrives that I can use alternately each time my machine tells me itstime to create a new backup file.
