Windows 10: storAHCI.sys long delay in response with AHCI/NVMe mode and HDD

The Storage test is freezing/responds after very long time in the field with AHCI/NVMe mode and HDD. Application is sending commands using win32 DeviceIoControl API and IOCTLs. However, the response is frozen/very slow. Is this a known issue?OS : Microsoft Windows 11 Pro v10.0.22621 Controller: Standard ATA AHCI Controller v10.0.22621.2506 Storage: SEAGATE ST500LM030-1RK17D WKP6BVWX and CL1-3D128-Q11 NVMe SSSTC 128GB

NVMe and AHCI? New system SSD + HDD

Hey guys.

I'm building my brother's new PC and he is gonna have a Samsung 960 EVO m.2 SSD which is NVMe
and a 1TB 7200 Hard Drive.

How would I set up the drives? Considering I'm mixing both NVMe and AHCI?

My bro hasn't decided on the exact motherboard/cpu combo yet, either Intel's Z270 or AMD's X370

I'm so used to drives being SATA (AHCI) for both SSD + HDD combo and I've never used any NVMe drive.

What happens if he goes with NVMe SSD and a SATAIII one thats AHCI? How do I set them up then?

Thanks in advance!

 

NVMe to HDD to NVMe

Hi

Welcome to Microsoft community.

It sounds like you want to migrate your operating system from your current NVMe SSD to a new one, and you're considering using an HDD as a temporary storage medium. Here are the general steps you could follow:

1. Backup Your Data: Before you begin, make sure to backup any important data to an external drive or a cloud storage service.
   
2. Clean Install on HDD: Install a clean version of Windows on your HDD. You can do this by creating a bootable USB with the Windows installation media, booting from this USB, and selecting your HDD as the installation destination.
   
3. Swap SSDs: After the installation, shut down your computer, remove your old SSD, and install your new one.
   
4. Clone HDD to SSD: Use a disk cloning tool to clone the Windows installation from your HDD to your new SSD. There are many free and paid disk cloning tools available, such as Macrium Reflect or Clonezilla.
   
5. Set Boot Priority: After cloning, restart your computer and enter your BIOS settings. Set your new SSD as the first boot priority.
   
6. Format HDD: After everything is working correctly on your new SSD, you can format your HDD to use it as regular storage.
   

However, it's worth noting that you could simplify this process by cloning your old SSD directly to your new SSD, without needing to use the HDD as a temporary storage medium. This would require a NVMe to USB adapter or an enclosure, which can be purchased relatively inexpensively.

Always remember to backup your data before performing any major operations like these.

Aktiver ahci i windows 10 home.

Hi Moffe Nielsen,

Thank you for posting to Microsoft Community.

If you want to install Windows OS on a Solid State Drive and boot it successfully after enabling AHCI in the bios, you can also follow the steps below to enable AHCI mode.



Method 1: Enable AHCI Mode via Command Prompt

• Hit Start, type “command,” right-click that result and choose “Run as administrator.”
  
• Type bcdedit /set {current} safeboot minimal into the dialog box and press the Enter.
  
• Close the window and restart the computer to enter the BIOS.
  
• Enable SATA AHCI mode in BIOS with the same steps as in Method 1, and then exit to boot into Windows safe mode automatically.
  
• In the safe mode, open the Command Prompt (Admin) and type into
  bcdedit /deletevalue {current} safeboot, and then hit the
  Enter.
  
• After all of the steps, you can now restart the PC. You will successfully boot a Windows after enabling AHCI mode in the BIOS.
  

Method 2: Enable AHCI Mode via Registry Modification:

• Press Win+R to open the Run window. Type regedit and hit Enter to open the Registry Editor.
  
• As the Registry Editor opens, go to the following location
  

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorV

• Select iaStorV. In the right panel, double click on the
  Start DWORD to modify its value.
  
• Set the value to 0 for AHCI.
  
• Now again browser to the following location
  

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorAV\StartOverride

• Select StartOverride, and then in the right pane, double tap on the 0 DWORD to modify its value.
  
• Set the value to 0. Click OK.
  
• Now again navigate to the following location
  

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci

• In the right panel, double tap on the Start DWORD to modify its value.
  
• Set the value to 0.
  
• Again go to the following location
  

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride.

• If you do not find the StartOverride, then close the Registry Editor, else continue to below steps.
  
• In the right pane of
  StartOverride, double click on 0 keyword and set the value to 0.
  
• Close the Registry Editor.
  
• Boot the computer to your BIOS or UEFI firmware settings.
  
• In your BIOS or UEFI firmware settings, enable AHCI, and save & exit to apply the changes. Restart the computer.
  

Disclaimer: The registry is a database in Windows that contains important information about system hardware, installed programs and settings, and profiles
of each of the user accounts on the computer. Windows often reads and updates the information in the registry.

Normally, software programs make registry changes automatically. You should not make unnecessary changes to the registry. Changing registry files incorrectly can cause Windows to stop working or make Windows
report the wrong information.



Please take a backup of the registry. Follow the steps given in the link below:
