Issue: How to fix SMART Hard Disk Error 301 in Windows?

Hello. For a few months not, I receive the black screen error SMART Hard Disk Error 301 every time before Windows starts loading in. Nothing has happened so far when it comes to my laptop's usability, so I wondered how do I fix this error for good?

Solved Answer

SMART Hard Disk Error 301 is an error message which is shown right before booting into Windows, and it indicates that the hard drive on the computer is failing. It occurs during this stage of the bootup because the firmware performs checks on the system, looking for issues with the hardware. If you received this error, it means that this check found hard drive corruption, and you need to take action as soon as possible.

SMART Hard Disk Error 301 is unique to HP laptops only, as it is a result of an HP SMART check – a customized version of power-on-self-test, otherwise known as POST,^[1] which is a diagnostic testing sequence initiated by all Windows machines before it begins to load all the needed components.

Once the boot sequence begins, users experiencing this problem would see the following message:

SMART Hard Disk Error

The SMART hard disk check has detected an imminent failure. To ensure no data loss, please backup the content immediately and run the Hard Disk Test in System Diagnostics.

Hard Disk 1 (301)

As the message claims, it is important to backup all the data stored on the hard drive, which should be done immediately. Unfortunately, some users said that they were unable to boot into Windows completely after receiving the SMART Hard Disk Error.

While the reason for the error is a failing or corrupted hard drive, there are several reasons why the error might show up in the first place. Most commonly, it is related to overheating problems (which are well known on laptops overall), physical hardware damage, or, in some cases, system file corruption and malware infections.

In this article, we will show you how to fix SMART Hard Disk Error 301 correctly and take appropriate actions once such error is observed. Regardless if you can or can't boot into Windows, you should perform several troubleshooting steps we provide below.

Fix 1. Restart your computer

If you are experiencing SMART Hard Disk Error 301 for the first time, the first thing you should do is try to restart your computer. The error might be a false positive, so it is worth checking whether it occurs again after restarting your laptop.

• Completely turn off your computer
• Pull out the battery plug if it is connected to the socket
• Remove the batter fully
• Now, press the power button on your laptop and hold it for around 30 seconds
• Put the battery back in and try starting the device once again – see if the problem is solved.

Fix 2. Test hard disk from the BIOS
