What is an AHCI controller driver?
Advanced Host Controller Interface (AHCI) is a technical standard for an interface that enables software to communicate with Serial ATA (SATA) devices. These peripheral component interconnect (PCI)-class devices move data between system memory and SATA storage media. To know if the AHCI driver is installed on your Windows 11/10 computer, in Device Manager, under the IDE ATA/ATAPI Controllers section, check for an entry that contains the acronym AHCI. If an entry exists, and there is no yellow exclamation mark or red “X” over it, then AHCI mode is properly enabled.
What is the SATA controller driver?
A SATA controller (serial ATA controller) is a hardware interface that connects a hard drive to a computer’s motherboard and manages or directs data flow. Normally, the SATA controller driver can be found on the CD or website of the system, motherboard, or SATA controller card manufacturer. If the SATA controller is recognized during Setup without special drivers, then you can complete the installation.
