The solution is simple to activate / switch from IDE toAHCI in Windows 8.1 and 8 via storahci!
For this purpose, please enable AHCI via registry in the Windows 8.1 / 8! In Windows 7, it was still called Msahci.sys! But this as a sideline!
To run the registry in Windows 8.1 and 8, press the [Windows + R] key combination, then simply enter the text regedit and confirm the command by pressing Enter!
1.) ... The registry entries in Windows 8 for AHCI change!
2.) ... Download the "storahci" settings for Windows 8.1 and 8!
3.) ... What are the advantages / disadvantages when using AHCI on Win 8.1 / 8?
... see Image-1 Arrow-1 and 2).
Then restart your Windows-8.1 / 8 computer! And activate / switch from IDE to AHCI in the PC BIOS at PC-Boot [Del.-Key].
Value 1: (... see Image-1 Arrow-1)
"Start" set to "0"
And Value 2: (... see Image-1 Arrow-2)
"0" to the value "0" (zero)!
If you want to change the settings via a registry script, you can download it:
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci] "Start"=dword:00000000 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride] "0"=dword:00000000After downloading, simply open the zip file / folder "ahci_Windows-8.1_and_Win-8.zip"
and open and run by a right-click mouse (... see Image-2 Arrow-1)!
The Windows 8.1, or 8 starts quickly and the requests on the disk are accelerated by 10-20 percent!
But it also happens that older hard disks that do not get along so well and it comes to freezing, or the MS-Explorer is a few seconds paralyzed!
It is then quite annoying to work, here I recommend turning off, or switch from AHCI mode to IDE mode!
If multiple operating systems are installed on the same computer, this should also be changed to AHCI, otherwise you have to change the AHCI / IDE BIOS entry again! The operating system on which the AHCI was not enabled, so it can not start (boot)!
