Good Morning
Thank you for contacting the community.
Have you tried the hard drive diagnostics: Power on > Tap F12 > Diagnostics > and run them from there.
Also, do you have any swaps, were you could possibly test a known working drive in the system. The best thing to do would be to run the complete diagnostics, this will also test the memory and the board.
Failing there being any hardware issues, its possible that you may need to run a chkdks/r or full operating system re-install.
Regards
Kevin
