You can buy Compaq and also HP System Recovery or Restore discs (CDs or DVDs) from this company:
They have all Toshiba Satellite laptops, including HP Pavilion DV2000, DV4000, DV5000, DV6000, DV8000, DV9000 and so on. Find yours in their website:
http://www.digitalmedia-labs.com .
They keep prices very low and ship right away, free shipping in the USA. Best place to get what you need.
Hope this helps
