Fix AHCI Port0 Device Error on Windows computer

What is the AHCI Port0 Device Error?

The AHCI device error is generated from BIOS. SMART has detected that your hard drive at port 0 is faulty, and the drive may or may not be accessible. Your hard drive can fail at any time. If you are using a desktop if you can, try to change the port where the hard disk is connected. If you still encounter the issue, this might be due to hard disk itself.  You can troubleshoot the issue by running the Check Disk utility, disabling the failing hard drive, and checking the port.

Fix AHCI Port0 Device Error on Windows computer

This AHCI Port0 Device Error does not usually occur due to the operating system failure; instead, it occurs when your computer detects an issue with your hard drive at Port 0 or Driver corruption, missing files, etc. Take these steps to resolve this issue:

  1. Check Physical Connectivity
  2. Run Check Disk
  3. Reset BIOS settings
  4. Check the health of your hard disk using a third-party tool
  5. Replace the hard drive.

To get started, press F1 when you see this error screen to go to your desktop. Once here, to be safe, backup your files to an external hard drive.

1] Check Physical Connectivity

First of all, we should restart the computer. Sometimes by doing this such issues get resolved. If restarting the computer doesn’t fix the problem, then make sure that all cables connecting the storage device to Port 0 are securely plugged in. If you have a spare SATA cable then use that cable, this could help resolve such an issue.

2] Run Check Disk

You can use this solution if your computer boots normally after showing an error. Check Disk (CHKDSK) is a Windows built-in tool for detecting and fixing disk corruption. This solution could help resolve the said error.

  • Press the Windows key and type Command Prompt in the search bar.
  • On the right side of the window, select Run as administrator.
  • Now click Yes in the User Account Control(UAC) prompt.
  • Type the following command in Command Prompt.
 chkdsk /r
  • Press the Y button when it asks to confirm the scan and then press Enter button.
  • Once the Windows scan is completed, it automatically repairs them.
  • Finally, restart the computer to see the effect.

Hopefully, your issue will be resolved now.

4] Check the health of your hard disk using a third-party tool

Macrorit Disk Scanner

There are various third-party disk error checking software that you can use to check the health of your hard disk. Even though the command mentioned earlier, Check Disk, can tell you the health of your drive, these tools can convey to you the hard disk’s health status in detail.

You can use free utilities such as HD Tune hard disk utility, Macrorit Disk Scanner, or EaseUS Partition Master Free to check your device’s status. These tools can measure the drive’s performance, errors during scanning, health status, and much more.

5] Replace the hard drive

If you cannot resolve the said error using the above solution, then replacing the storage device will be the best option. But before replacing the storage device, we should connect our storage device to a different port. If everything is ok, then there is no need to do anything. But if this does not solve the problem, we must replace the storage device.

What should I do if the AHCI Port0 Device Error persists?

If none of the above solutions work, you should consider replacing the hard disk. Solid State Drives (SSDs) typically have a lifespan of 7-10 years, while Hard Disk Drives don’t last for more than 5-7 years, and the former offer significantly better performance. Hence, you should get an SSD drive, restore the backups, and enjoy much smoother performance.
