Note that all hard disk controllers provide hard disk status information in single/standalone mode only unless RAID mode is listed for the appropriate hard disk controller (RAID controller). Note: the firmware update for ASMedia ASM1051 USB3.0 bridge may work with enclosures, adapters based on this chip to get the missing status information.

-->Note
The ATA port driver and ATA miniport driver models may be altered or unavailable in the future. Instead, we recommend using the Storport driver and Storport miniport driver models.

Download Drivers for SATA AHCI Controller for Windows 10 By now you must know the importance of SATA AHCI Controllers in your computer. And the drivers for this controller are equally important as they provide communication between Windows 10 and the actual controller on your computer’s motherboard itself. To download the Media Creation Tool (Click on Download Tool Now), with that you can download the latest Windows 10 ISO (Select Create Installation Media for Another PC), you can create a bootable USB flash drive (min 8GB) using that tool.
In addition to the SCSI Port Driver and the Storport Driver, Windows Vista and later versions of the Windows operating system provide the ATA port driver (Ataport.sys), a storage port driver that is especially suitable for use with IDE controllers.
The most significant difference between the ATA port driver and other system-supplied storage port drivers is the protocol that the ATA port driver uses to communicate with other drivers. All other system-supplied storage port drivers use SCSI request blocks (SRBs) to communicate both with higher-level drivers, such as storage class drivers, and with miniport drivers. The ATA port driver uses SRBs to communicate with higher-level drivers only. To communicate with its miniport drivers, ATA port uses a packet called an IDE request block (IRB), which is defined by the IDE_REQUEST_BLOCK structure. IRBs are better designed than SRBs to the characteristics of ATA devices.
Another difference between the ATA port driver and other system-supplied storage drivers is that the ATA port driver shields ATA miniport drivers from certain requirements that are defined by the SCSI standard. For example, the ATA port driver uses ATA commands to collect the equivalent of SCSI sense data from the ATA miniport driver, translates the data so that it complies with a SCSI sense data format, and passes the data to higher-level drivers as if it were SCSI sense data. Therefore, ATA miniport drivers do not have to respond directly to requests from higher-level drivers for SCSI sense data.

The ATA miniport driver interface closely resembles the SCSI port driver interface. Therefore, if you have already written a SCSI miniport driver, you should be able to easily learn how to write an ATA miniport driver. Drivers for current ATA/ATAPI technologies, such as Serial ATA (SATA), should use the higher performance Storport miniport interface.
Together with the ATA port driver, the operating system provides a default ATA miniport driver and a default controller minidriver. The system-supplied default drivers work for most controller hardware, and we strongly recommend that the default minidrivers be used wherever possible.
Symptoms
After you use the BIOS setup of a Windows 7-based computer or a Windows Vista-based computer to change the Serial Advanced Technology Attachment (SATA) mode of the boot drive to use either the Advanced Host Controller Interface (AHCI) specification or redundant array of independent disks (RAID) features, you receive the following error message when the computer is restarted:
Cause

This issue occurs if the disk driver in Windows 7 or Windows Vista is disabled. This driver must be enabled before you change the SATA/RAID mode of the boot drive.
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
322756 How to back up and restore the registry in WindowsTo resolve this issue, enable the AHCI driver in the registry before you change the SATA mode of the boot drive. To do this, follow these steps:
Exit all Windows-based programs.
Click Start, type regedit in the Start Search box, and then press ENTER.
If you receive the User Account Control dialog box, click Continue.
Locate and then click one of the following registry subkeys:
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesMsahci
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesIastorV
In the pane on the right side, right-click Start in the Name column, and then click Modify.
In the Value data box, type 0, and then click OK.
On the File menu, click Exit to close Registry Editor.
More Information
During the Windows 7 or Windows Vista installation process, any unused storage drivers are disabled. This behavior speeds up the operating system's startup process. When you change the boot drive to a driver that is disabled, you must enable the new driver before you change the hardware configuration.
For example, assume that you install Windows Vista or Windows 7 on a computer that contains a controller that uses the Pciide.sys driver. Later, you change the SATA mode to AHCI. Therefore, the drive must now load the Msahci.sys driver. However, you must enable the Msahci.sys driver before you make this change.
This issue affects only the boot drive. If the drive that you change is not the boot drive, you do not experience this issue.
AHCI provides several features for SATA devices. These include hot plug functionality and power management functionality. For more information about the AHCI specification, go to the following Intel website:
