bad xp pro install disk, any fixes?

I have "student edition" (read corp) XP Pro SP2 disk that I bought from my school about two years ago for a friend, long story short they didn't ever come get it from me and it sat in a sleeve until a week ago when I remembered I still had the darn thing.

The disk will not install the OS as 12-18 files are corrupt or unreadable due to disk errors (check done with CDCheck). nLite reports similar issues with, I assume, the same files. The disk itself appears to be in good shape and has very little if any damage or scratching and I know that my disk drive is in good order so I think the CD itself was defective when I bought it.

What can I do to fix this problem? If I can borrow an XP pro disk from a friend and use my CD key will it matter what build, SP# or edition (retail, OEM, corp)? If SP3 disks will accept SP2 era keys I think I can find a disk but I wasn't sure it would work as I recall there being issues between SP1 and SP2 era keys and I know that SP3 era keys are longer.

Also, I did for a bit think about finding a CD image torrent but that just seemed first probably illegal, second very prone to crazy virus fun and third very hard to track down a non-modified version.

 

Windows XP keys come in three different types: OEM, Retail, and corporate (yours). As such you can only use a corporate key with a corporate CD. Also, I believe that the keys remain the same across service packs.

 

Please don't talk about torrents, etc, or anything fishy like that since we don't allow it. Thanks.

 

To determine whether the CD is damaged, follow this procedure and post back what happened:
1. Insert the CD into your computer's CD-ROM or DVD-ROM drive (or, in case your PC in question has no OS installed yet, to another PC with a working optical drive).
2. Click Start, and then click Run.
3. In the Open box, type cmd, and then click OK.
4. At the command prompt, change to the CD-ROM drive (this is typically drive D or E). To do so, type d: or e: (or whatever the letter of your CD-ROM drive is), and then type the following command:
dir /s
5. If you receive an error message, the CD is damaged, or the CD-ROM drive cannot read the CD.

No, they don't.

 

Trying to use a sp1 key with a sp2 disc has never worked for me.
