I'm trying to reformat my hard drive and reinstall my copy of windows xp pro...I've done this many times in the past, but for some reason now I keep getting errors saying that certain files are missing when its copying setup files onto the HD from the disc. I popped the disc into my laptop and the files are definetely there, and I also made a copy of the disc, just to make sure it wasn't scratches on the disc. I used both my DVD-ROM drive and DVD-RW drive, so I don't think the drive is the problem. Any ideas?
