Many SATA controllers offer selectable modes of operation: legacy Parallel ATA emulation (more commonly called IDE Mode), standard AHCI mode (also known as Native Mode), or vendor-specific RAID (which generally enables AHCI in order to take advantage of its capabilities). Intel recommends choosing RAID mode on their motherboards (which also enables AHCI) rather than AHCI/SATA mode for maximum flexibility.[3] Legacy mode is a software backward-compatibility mechanism intended to allow the SATA controller to run in legacy operating systems which are not SATA-aware or where a driver does not exist to make the operating system SATA-aware.
Some operating systems, notably Windows Vista, Windows 7, Windows 8, Windows 8.1 and Windows 10, do not configure themselves to load the AHCI driver upon boot if the SATA controller was not in AHCI mode at the time the operating system was installed. Although this is an easily rectifiable condition, it remains an ongoing issue with the AHCI standard.

Technically speaking, this is an implementation bug with AHCI that can be avoided, but it has not been fixed yet. As an interim resolution, Intel recommends changing the drive controller to AHCI or RAID before installing an operating system.[3] (It may also be necessary to load chipset-specific AHCI or RAID drivers at installation time, for example from a USB flash drive).
On Windows Vista and Windows 7, this can be fixed by configuring the msahci device driver to start at boot time (rather than on-demand). Setting non-AHCI mode (i.e. IDE or Combined mode) in the BIOS will allow the user to boot into Windows, and thereby the required registry change can be performed. Consequently, the user then has the option of continuing to use the system in Combined mode or switching to AHCI mode.[8]Inter alia with Windows 10 and 8, this can be fixed by forcing the correct drivers to reload during Safe Mode.[9]
In Windows 8, Windows 8.1 and Windows Server 2012, the controller driver has changed from msahci to storahci,[10] and the procedures to upgrade to the AHCI controller is similar to that of Windows 7.[11] On Windows 8, 8.1 and Windows Server 2012, changing from IDE mode to AHCI mode without first updating the registry will make the boot drive inaccessible (i.e. resulting in a recurring boot loop, which begins with a Blue Screen error).
A similar problem can occur on Linux systems if the AHCI driver is compiled as a kernel module rather than built into the kernel image, as it may not be included in the initrd (initial RAM disk) created when the controller is configured to run in Legacy Mode. The solution is either to build a new initrd containing the AHCI module, or to build the AHCI driver into the kernel image.[12]
On a Windows based system, the operating system detects the SATA controllers during boot and loads device drivers supporting the configured SATA mode. For the purpose of this article, only AMD SATA controller for AHCI mode is covered.
The AMD SATA controller component is not compatible with and will not be offered nor installed by the chipset driver package on AMD desktop systems running Window 10 or using AMD Socket AM4 and Socket TR4 chipsets. Forcing a manual driver installation via Device Manager on these systems is not supported and may cause stability and performance issues with some mass storage devices, such as solid-state drives (SSD).
If the system is not using Standard SATA AHCI Controller driver and is experiencing stability and performance issues with connected SATA devices, use the Roll Back Driver option to restore to the default controller.
The ahci driver is a SATA framework-compliant HBA driver that supports SATA HBA controllers that are compatible with the Advanced Host Controller Interface 1.0 specification. AHCI is an Intel-developed protocol that describes the register-level interfacefor host controllers for serial ATA 1.0a and Serial ATA II. The AHCI 1.0 specification describes the interface between the system software and the host controller hardware.
The ahci driver currently supports the Intel ICH6/7/8/9/10, VIA vt8251 and JMicron AHCI controllers which are compliant with the Advanced Host Controller Interface 1.0 specification. The Intel ICH6/7/8/9 and VIA vt8251 controllers support standard SATA features. The ahci driver currently supports hard disk, ATAPI DVD, ATAPI tape, ATAPI disk (i.e. Dell RD1000), hotplug, NCQ (Native command queuing) and Port multipliers (Silicon Image 3726/4726). Power management is not yet supported.
AHCI is supported on Windows Vista and later versions of Windows; Linux since version 2.6.19; OS X; and various open source operating systems, such as OpenBSD, NetBSD and FreeBSD. While Windows Vista and Windows 7 include the AHCI driver, those OSes won't install AHCI if it's not enabled on the boot drive's controller.

AMD AHCI Compatible RAID controller have limitations compared to hard disk controllersof different manufacturers. By using this controller (and especially with an older driverfor AMD AHCI Compatible RAID controller), only limited hard disk information reported. However, this is not really related to Hard Disk Sentinel and completely independent from the hard disk model(s) used.
Generally, hard disk controller drivers affect how special commands (for example the statusdetection) are transferred to the hard disks / SSDs and some drivers may offer less functionsthan others and may completely block such special commands.
Hard Disk Sentinel 4.60 and newer versions show the current disk controller and its currentdriver version (and release date) on the Information page. This can be used to quickly verifythe driver and replace it from the Driver Zone page if required, for example if the status of hard disks can't be detected.
right click on Computer, select Properties -> Device Managerlocate "AMD AHCI Compatible RAID Controller" device. It is located in the Storage controllers (or in some cases the IDE/ATA controllers) section.Right click on this device, select Update Driver Software and select "Browse my computer for driver software"Specify the folder C:\AMDAHCIAfter clicking on Next, the installation begins and when completed, you will need to restart the computer, thenfurther hard disk status information should be detected and displayed.
That's the maximum possible with AMD RAID Controller and it is not a bug / limitation of Hard Disk Sentinel, but a bug / limitation of the AMD RAID controller (even with therecommended "best" driver available for that).
We can just hope that one day AMD will change their mind and hear the requirements of users. AMD: we want to monitor the complete status of ALL hard disks / SSDs configuredas RAID arrays and you should release a new driver which allows this.Wonder why AMD still does not allow this - as complete hard disk monitoring is possible with dozens of RAID controllers from all major manufacturers by Hard Disk Sentinel (listed atCompatible hard disk controllers, RAID controllers section, so have no idea why their users are not important for AMD, why they ignore our requirements.
Note: newer Windows operating systems may automatically have driver version 3.6 or 3.7 installed as default. The numbers are confusing as they may indicate the driver is newer - but it is actually older and worse than the recommended driver.These 3.6 and 3.7 versions do not provide access to any hard disk status information. Upgrading the driver of the AMD AHCI Compatible RAID controller to the recommended 3.2.1540.92 version helps in such situations.
In the worst case, you may try to install the "Standard AHCI 1.0 Serial ATA Controller" driver.This is a built-in driver in Windows so there is no need to manually download and extract.When standalone, non-RAID configuration used, it can work correctly for the AMD controller.
To install this driver, proceed the above mentioned installation stepsright click on Computer, select Properties -> Device Managerlocate "AMD AHCI Compatible RAID Controller" device. It is located in the Storage controllers (or in some cases the IDE/ATA controllers) section.Right click on this device, select Update Driver Software Browse my computer for driver softwareThen select "Let me pick from a list of device drivers on my computer", and if required, enable the "show compatible hardware" option - and then Windows should show the "Standard AHCI controller" driver also as an option. 2ff7e9595c
