If the Hard Drive Test displays an error message and a warranty ID code, contact HP.
The customer service agent will ask you for the warranty ID if they need to set up a repair or replace the hard drive. The HP warranty ID contains four fields of six characters each, such as XXXXXX-XXXXXX-XXXXXX-XXXXXX, where X is an alpha-numeric character.
Having a warranty ID does not mean that your computer is still under warranty. The agent will verify your warranty when you contact HP.
