unfortunately, you're in the same boat as most other hp owners who can't hang onto their recovery disks. What other drivers are you needing or what device are you needing drivers for? Id your hardware and we'll attempt to help. If you are unable to id the hardware, here's some software that might help.

An alternative program is Belarc Advisor from www.belarc.com (a little more simple to use than Everest but not as good about identifying a place to find the driver).
