Your HDD , most likely has failed. Take a look at this: http://h30434.www3.hp.com/t5/Notebook-Operating-Systems-e-g-Windows-8-and-Software/hard-disk-error-code/td-p/1118627 OR: http://h30434.www3.hp.com/t5/Desktop-Hardware/Hard-drive-failure-predicted-BIOHD-7-error-code/td-p/84080

Compaq laptop has detected a SMART fault. You should backup your data and test the harddrive with the maufactures diagnostics like Seatools for Seagate. Run a short DST. Drive may pass. I would still replace it. Clone your current drive to the new one. The drive is probably on its way out.

If you are getting errors from the hard drive diagnosis, the solution is--replace the hard drive. Don't mess with it. You can install the defective hard drive as a second drive and possibly lift data from it. Keep messing with it and you may lose more data.

From your description I understand that the DVD drive is not working and you have code 10 error in device manager.
Do not worry, run the following fix on the pc and then restart the notebook.
