Hi Helen, when you say program disks, what do you mean?
Assuming your drive can read ok but cannot write, I qould firstly try different software. You can go to nero.com to get hold of a trial version to check it, or the windows burner is quite good too, but I dont know if that is the one that you are using.
You didnt mention CD-Rs. Try these if you havent. Not a straighforward solution to problems like these. Worst come to worst you can try the HP recovery, just to eliminate the software being an issue.
Hope this advice helps
