I have three hardrives that were previously in other older computers. One of the hdd's has Windows98 installed on it and the other two have other somewhat improtant files on them. I recently just built a new comp with a new hdd in it and installed Windows XP on it. When hooked up one of the old drives(w/OS) in place of my new hdd and booted up the comp I get a message that says "cannot find OS" or something like that. I kind of half expected something wouldn't work. So.... How do I access my old hdd, and the two hdd's without an OS, so I can put all my files on a disk to put on the new hdd? If it matters, I do plan on reformatting all three of the old hdds.
