Moreover, many motherboard manufacturers supply products with a default option khổng lồ support PATA compatibility mode – IDE.

The matter is that operation of disk controllers in AHCI mode is supported in operating systems beginning with Windows Vista. That is, if you connect a disk with Windows XPhường. lớn the system with AHCI-enabled controllers, you will run inkhổng lồ a BSOD error (“the blue screen of death”). On the other hand, any SATA disk can work in IDE mode. Without kowing it, many users will feel no difference. In this way, computer manufacturers are trying lớn avoid possible problems with compatibility of hardware và software.

Another important difference between IDE and AHCI concerns working with SSDs. Rethành viên that you can’t install an operating system on an SSD in IDE mode – it requires AHCI to be enabled.

How to Find out Which Mode the Computer’s Controller is Using?

It is quite possible that AHCI mode is already enabled in your PC. It can be checked in several ways:

Method One

Go to lớn Device ManagerOpen the section “IDE ATA/ATAPI controllers”If there is a device containing “AHCI” in its name as in our case, it means that AHCI mode is used in this computer.

Method Two

Find an thành tựu with the name «Storage options», «SATA Mode», «SATA Emulation» or anything similar.

If the value of such sản phẩm is «AHCI» then AHCi mode is already enabled.

The matter us that if you just enable AHCI mode after Windows installation, you will face a BSOD error, INACCESSABLE_BOOT_DEVICE (which is known as “xanh screen of death”) or your system will refuse to boot, getting stuck in a series of restarts. That is why it is recommended to lớn enable AHCI before installing Windows.


Please take note, that in some computers, there is no BIOS option khổng lồ change to lớn AHCI mode. In this case, the problem can sometimes be fixed by updating the BIOS.
