This can conduct a hard drive test which comes up with some fail like 7 .
You should re-test the hard drive to confirm that it continues to fail testing:
If it fails testing again, chances are it is going bad or has failed as suggested by gavinseabrook
I have searched for an HP error: 0x400110020000 10a
unsuccessfully; however, error: 0x400110020000 100a
yielded many hits. A number of these reveal a bad hard drive.
If you have to replace the hard drive, the following link trying to re-install hp recovery disks
, when you arrow down, gives some special instructions that might be helpful. Once the drive has been replaced, you should
be able to re-install the OS from your recovery disks; however, there is no guarantee that they will work unless you have previously used them to re-install. Not to fret, as replacement disks can always be obtained from HP.
