Solved Enabling AHCI on Seagate SATA hard disk drive

December 15, 2011 at 14:11:24
Specs: Win7 Ultimate SP1, Intel QuadCore i5-760@2.80GHz_3.50 RAM
I have Asus P7P55d-E LX mboard & I would like to utilize AHCI on my Seagate SATA hard disk drive. In my BIOS setup I found 2 configurations regarding AHCI. [1] under 'Storage Configuration', Enhanced SATA with the option to set as IDE (default), RAID, AHCI; and [2] under 'Onboard Devices Configuration', Marvell 9123 Controller with the option to set as DISABLED, IDE (default), ACHI. Do I set both configurations to ACHI to achieve performance increase in my storage device? Note that AHCI support is enabled by default in my OS in the Registry. Thank you for your time.

I understand your frustration. That said, the difference in performance in practice is minimal. The specs of the SATA drive are probably just as important as running in AHCI mode vs. IDE.

If you ever need to perform a fresh install that would be the time to change the setting.

Which one you set to AHCI depends on which controller/s you are connecting the SATA hard drive to. The Marvell controller is a SATA III (6GB) type.

Keep in mind that if you already have Windows installed and you change that setting you may need to re-install.

See the MB spec link below to help determine which is which, if you don't know.

I have Seagate hard drive connected to SATA1, LiteOn DVD writer to SATA3 & Asus DVD writer to SATA5. According to the manual, these are the Intel SATA connectors.

As to your concern about enabling ACHI when Windows is installed, read some articles about it, example on "http://support.microsoft.com/kb/922976". Will this work on my computer?

You can try that. Vista and Windows 7 have SATA drivers included so if a repair is initiated the correct driver should be available.

Just so you know, while running in AHCI mode is preferable you may not see any improvement in performance.

As you should already be doing, be sure to backup your files before trying to change the mode. You should always maintain at least two copies of any files you wish to keep.

Sorry for the delayed reply, had an emergency to attend to. So back where we left off. Since the OS was installed in IDE mode (default), I did a small registry edit to enable the AHCI driver before switching the SATA mode for the intel controller to [AHCI] in BIOS setup (http://support.microsoft.com/kb/922976). Rebooted just fine and updated currently installed Microsoft's Standard AHCI 1.0 SATA Controller driver to latest Intel Rapid Storage Technology driver & rebooted to finalize driver installation. Everything seems to work fine but when I inserted a game disc on DVD RW Drive #1, a dialog box appeared which read: Cannot locate cd-rom; "Please insert the correct CD-ROM, select OK and restart the application". Tried on DVD RW Drive #2 & other game discs with the same result except on data discs which works fine. And also games without the need to insert their respective game disc can be played too. Can each of the SATA devices can be configured individually even though all are connected to the Intel SATA ports? I mean, the hard drive to AHCI & the 2 optical drives to IDE mode. And lastly, I keep activating my OS everytime I turn my desktop on, why is that? Any thoughts? There must be a way on how to fix this problem?

If you have the optical drives connected to the Marvell controller, switch them to the other one.

Watch the POST screens to verify the optical drives are being configured there.

"And lastly, I keep activating my OS everytime I turn my desktop on, why is that?"

Do you mean you need to activate with Microsoft each time?

My hard drive along with the two optical drives are connected to the board's Intel SATA connectors. And yes, I have to get online to activate my OS everytime I switch my PC on. By the way, Happy Holidays!

You didn't indicate weather or not the optical drives are seen in the POST screens at start up. If they are seen in the POST screens but not in Windows then I suggest you go into Device Manager and remove the optical drives, reboot and see what happens.

Cannot confirm whether optical drives are seen on POST screens because it only flashes a fraction of a second. But are visible in "My Computer" window under Devices with Removable Storage [1] (G:) DVD RW Drive & [2] (H:) DVD RW Drive along with the 4 hard disk local drives listed as C; D; E & F. And as mentioned earlier, both optical drives are able to read data dics but not game discs.

"both optical drives are able to read data dics but not game discs".

If this means that the drives do not auto detect then try opening the disk using Windows Explorer.

Auto detect is an optional setting that you set.

To change those settings go to Control Panel AutoPlay.

Autoplay is turned-on on all media. Even tried to manually run the game through it's executable file but to no avail.
Since I can't get to automatically launch the other games when inserting their respective game dics in the installation
drive (other games installed do not require game disc to run & they still work normally), I did try a little experiment
(call it what you will) to confirm my suspicions. All 5 games were installed before switching my drives to AHCI mode &
were operating normally untill I switched to AHCI mode & the games that needed their respective disc inserted to run
suddenly didn't work thus the error message. So while in AHCI mode, I installed a new game that required a disc inserted
in the drive to launch the game automatically and it worked. The newly installed game played normally. Next,
uninstalled one of the games that stopped working after switching to AHCI mode & re-installed it back (now in AHCI
mode), and guess what, the game now works. Re-installation worked. I have no knowledge on computer science to
explain what just happenned, I guess sometimes a simple common sense will do the trick. I think we've got this
problem solved but I will be closely monitoring my PC in case any unexpected error(s) will arise just to be sure. And
now the next issue at hand is the "activation" part. The computer does not display any warning sign stating activation
required everytime the PC boots. I navigated to the Control Panel's System properties to check on the system rating
only to find that Windows requires activation. On every first boot (anytime) of the day, i am required to activate
Windows online with 30 days to comply with but on every reboot on the same given day I am still required to activate
online but with only 3 days left to comply with. This is on a day to day basis. This is a puzzle I do not understand. I do
not know if this is just an activation glitch or something. I have no idea why this is so. I probably will switch back to IDE mode if things won't work the way I want to. I'll give it a few more days to figure this out and maybe we'll get lucky. Thanks for your time.

Did you perform a registry hack about activation? I just read today about folks trying to get around activation hacking the registry. It doesn't work though.

Maybe the change you made with the MSKB caused the activation. I suggest you contact MSoft.

My OS is Windows 7 Ultimate with SP1_x86, OEM System Builder Pack. Genuine copy of Windows, legally registered and activated. The activation problem only appeared when I switched to AHCI mode, everything was OK before that.

When I switched to AHCI mode, the system also automatically switched the IDE/ATA/ATAPI controllers from Intel 5 Series SATA Storage Controllers to the system's Standard AHCI 1.0 SATA Controllers. I noticed the Seagate hard drive icon appeared on the Notification Area & when clicked, a tooltip appears which read "Safely Remove Hardware & Eject Media" which is normally associated when a USB Flash drive is inserted. But why a hard drive icon in a notification area? Odd and unusual. And on top of that, in Control Panel's Devices and Printers window under Devices section, added are the 2 optical drives and the hard drive along with the attached USB devices. I figured this wasn't right so I thought of updating the system's Standard AHCI 1.0 SATA Controllers to the latest Intel's Rapid Storage Technology Controller & driver which is supported by my Asus m'board. I've read on many articles updating the drivers usually does the trick and it did. Icon in the notification area along with the added items in the 'Devices' area all disappeared and I thought went well. And that's when i noticed the game discs & the activation problem. Updating did
resolve the problems but managed to come up with new ones. If this issue can't be fix, I have no alternative but to revert to it's default IDE state. I won't use this desktop on either controllers with issues.

Try performing a startup repair. The Google link below has several useful links on that topic.

I can't risk having anymore problems popping up each time I try a fix that seems endless. I've decided not to pursue the task in mind before it gets any worse. On the other hand, my desktop is back in it's normal, reliable & stable self. In the end I think that's what counts most. Thank you for your time and patience. Enjoy the holidays.
