How can you install XP on two hard drives on one computer?
I have accomplished this on my computer because I bought a second hard drive for the purpose of a backup along with additional space. However, the Maxtor hard drive that I bought had a floppy disk that came with it which had several functions ranging from hard drive setup to diagnostics to partitioning and image copy. The image copy feature is what allowed me to take a snapshot of my primary drive and format and copy it to my secondary drive, overwritng any existing files you may I had on it. You do, however, need to be aware that software and system conflicts can arise by running two sets of Windows XP on the same computer at the same time, albeit they're on two separate drives. That's why I prefer to do this ONLY to use the second drive as a backup, not as a supplement. If you need a second hard drive simply to supplement your primary drive for added disk space purposes, I wouldn't recommend putting the full operating system on it. Just leave it as is and use the free space as needed with your primary.
