SOLVED! AHCI Port0 Device Error

by

Usually, Windows won’t take much time to boot up so people should be able to get to their work with relative ease. That being said, it’s not uncommon for Windows to experience issues during the boot-up process and AHCI Port0 Device Error is one of them. The moment that error shows up, Windows users cannot access the main screen which disrupts their working schedule. Read to the end if you want to know how to overcome AHCI Port0 Device Error. 

The Root Of The Problem

In layman’s terms, the error is not related to the operating system because you will see it prior to the starting of OS. AHCI Port0 Device Error is in essence the work of S.M.A.R.T (Self-Monitoring, Analysis and Reporting Technology). S.M.A.R.T displays AHCI Port0 Device Error whenever it detects an issue with your hard drive at port 0. Issues that involve the drive include corruption, missing files, improperly installed device drivers, etc.

What You Could Do

Restart
