Hello

Hard Disk 1 Full (305) Hi, The 305 error would indicate that your Hard Drive is failing and will need to be replaced. If your notebook is still under warranty, contact HP and arrange to have the drive replaced

and get a set of recovery disk from HP , this would resolve the issue,

its not the hacker, its the hdd that is failing because of which you got black screen

A hacket can get into your system once the OS is loaded. They cannot hack when the computer is in BIOS or when you are doing recovery. The issue is with running recovery and not hacking.

Looking at the error code I can say that the hard drive has gone wrong and needs a replacement. Call HP and setup a service or take the unit to a authorized service center for HDD replacement.
