    Read full summary

    SMART Hard Disk Error 301 is an unpredicted error message that indicates hard drive failure or severe drive corruption. This error is related to HP laptops, which comes with HP SMART check embedded in the firmware. The HP SMART check is a customized version of Power-On-Self-Test (POST) check that scans hardware for issues when you boot the system. During the scan, if it finds a hardware-related issue, the firmware displays error code such as SMART hard disk error 301 when it encounters problems with the internal hard disk.

    Also, this error in HP notebooks is quite common and occurs unexpectedly. You never know when your HP laptop might throw this error. Moreover, it doesn’t let you boot Windows OS. Therefore, when the error 301 occurs, you must be prepared as it becomes crucial for you to act immediately and appropriately to prevent data loss. Below we have discussed a few troubleshooting methods along with a few tips and software solution that can probably help you solve the hard drive error before the situation worsens.

    Additionally, if the error isn’t fixed, the guide will also help you get your data back securely.

    Why SMART Hard Disk Error 301 Occurs?

    To solve the issue, we need to first understand the reasons to why SMART hard disk error 301 occurs. Then, accordingly, you can take measures to prevent such issues in future. Following are some of the factors that can lead to SMART hard disk error 301:

    • Outdated or Misconfigured BIOS
    • Loose connection
    • Application or Driver conflicts
    • Virus issues
    • File corruption
    • Unexpected shutdown
    • Power surge
    • Physical damage

    How to Solve SMART Hard Disk Error 301

    1. Change Boot Priority Order

    Turn off your HP laptop and then turn it on. Immediately start pressing BIOS key, usually F10 in HP laptops and desktops, continuously until you see the BIOS screen

    • Use left/right arrow keys and go to ‘Advanced’ tab
    • Using up/down arrow key, move the selection to ‘Boot Order.
    • Follow the on-screen instructions and move the hard disk to top in the boot order
    • Press F10 key to save changes and exit the BIOS

    Alternatively, you can press F9 key continuously after pressing the power button to enter boot priority order. Use up/down arrow key and select your hard drive to boot Windows.

    If the Windows starts, log in to your system and immediately backup your data. If it doesn’t boot up, proceed to the next troubleshooting method.

    2. Reset BIOS

    SMART disk error 301 can also occur when there is an issue with the BIOS/firmware. This issue could arise over a period as you use your system and tweak BIOS settings that sometimes coincide and lead to such errors.

    To solve this, you can update BIOS. When an update is not available, we recommend you to reset the BIOS configuration by following these steps:

    • Follow steps given above solution to enter the BIOS
    • Press F9 key to reset BIOS
    • Then press F10 to save and exit the BIOS settings menu

    Your system will reboot. Let it boot and if this fixes the error, immediately backup; else follow the next troubleshooting method.

    3. Reseat Hard Drive

    It’s possible that connection between the hard drive and the laptop might have loosened due to shock, physical damage, etc. Ensure a firm connection between the hard drive and the motherboard by reseating the hard drive.

    Be careful while playing with the internals of the laptop as it may further damage your laptop. If you are not familiar with 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.

    To hard reboot your HP laptop, follow these steps:

    • Shutdown the system
    • Disconnect the power cable
    • Remove the battery
    • Press and hold the power button for 15-20 seconds in order to discharge every bit of current left in the motherboard (inside capacitors, coils, etc.)
    • Wait for a few minutes and repeat once again
    • Then connect the battery and turn on your laptop

    Hopefully, this fixes the issue; if it doesn’t, the drive might have got corrupt. Follow the next method to recover your data and fix the drive error.

    5. Use Data Recovery Software

    The above-mentioned troubleshooting methods should fix the issue. However, sometimes, the hard drive gets severely corrupt, and common troubleshooting doesn’t work.

    So when the described methods fail, you must rely on a data recovery solution such as Stellar Data Recovery Standard. The software helps you recover your inaccessible data securely from a severely corrupt hard drive using the ‘Deep Scan’ functionality.
