As an HP notebook user, you may encounter error code “301”, which indicates that there is a hard drive problem in your HP laptops. The boring error unexpectedly appears between the middle of the work time when your computer tries to boot. This problem can be due to several reasons, such as an incomplete installation of the operating system, a conflict between software and applications, files infected with malware or viruses in the operating system, a corrupt download, etc. If the error occurs, it means that 90% of the registry has been corrupted. You can easily resolve this error on your own or simply dial the HP Notebook PC Technical Support phone number for quick assistance with technical expertise.

What are the causes of 301 hard drive error?

Hard Disk 301 error occurs due to several reasons. Following are some of the reasons that causes hard disk 301 error.

• SMART hard disk check Failure
• Broken IDE/SATA controller chip in the Motherboard
• Unexpected shutdown
• Physical damage to the hard drive
• Outdated or Misconfigured BIOS
• Virus attacks

Quick fixes to hard disk error 301

1. Change Boot Priority Order

Turn off your HP notebook, and then turn it on. Immediately press the BIOS button, usually F10 on HP laptops and desktops, until the BIOS screen appears.

1. Use the left / right arrows and go to the “Advanced” tab.
2. Using the up / down arrows, move the selection to “Start Order”.
3. Follow the on-screen instructions and move the hard disk upward in the boot order.
4. Press the F10 key to save the changes and exit the BIOS.

You can also press the F9 key continuously after pressing the power button to enter the boot priority order. Use the up / down arrows and select your hard drive to boot Windows. If Windows starts, log in to your system and back up your data immediately. If it does not start, go to the next troubleshooting method.

2. Reset BIOS

The SMART 301 disk error may also occur if there is a problem with the BIOS / firmware. This problem can occur over a period of time when you use your system and change sometimes coincident BIOS settings that cause such errors.

To resolve this problem, you can update the BIOS. When an update is not available, we recommend that you reset the BIOS setup as follows:

1. Follow the steps given above to enter the BIOS
2. Press the F9 key to reset the BIOS
3. Then press F10 to save and exit the BIOS settings menu.

Your system will restart. Let it start and if it fixes the error, back up immediately; otherwise, follow the next troubleshooting method.

3. Reseat Hard Drive

The connection between the hard disk and the laptop may have loosened as a result of shock, property damage, and so on. Make a strong connection between the hard drive and the motherboard by reinserting the hard drive. Be careful when playing with the internal parts of the notebook, as this may cause further damage. If you do not know the hardware part, skip this method.

4. Hard Reboot

While system reboot is the first step to troubleshooting, sometimes restarting a system doesn’t necessarily fix some issues such as SMART disk error 301. In such a case, you need to shut down the system and discharge traces of current from the motherboard. This is referred to as a hard reboot.
