Hard disk error

[DiegowG]

So I can’t factory reset my laptop and I keep getting a error that says “boot device not found and hard disk (3F0)”

@DiegowG -- the motherboard assigns "3F0" as the address of the device connected to the first SATA socket on the motherboard.

1. Check that the SATA cable is tightly connected to that first SATA socket.
2. Check that the other end of the SATA cable is tightly connected to the disk-drive.
3. Try a different SATA cable.
4. Check that one of the "power" leads (from the power-supply) is tightly connected to the disk-drive.
5. After having the computer powered-on for 10 minutes, is the disk-drive any warmer to the touch than before the computer was powered on?  If not, that is bad -- it should be generating some heat.
6. With the computer running, carefully and lightly touch the top of the disk-drive. Not feeling any vibration is a bad sigh.
7. With the computer running, listen to any noise from the disk-drive, as the read/write mechanism moves across the recording surface. They should be a small "rattle" (like a few tiny rocks inside an empty jam-jar). No noise means that the mechanism is either not moving, or the motherboard is not requesting it to move, to do any input/output.

Short answer: your disk-drive could have "failed", and it must be replaced.

Hi,

 Run HP Diagnostics.

Start the PC when powered off. Tap the "ESC" key.

Select "F2". Run system and component tests.

If you get a "fail", it probably will be the disk-drive that has failed, and it needs to be replaced.
