Q: set SATA controller to operate in AHCI mode

How do I set SATA controller to operate in AHCI mode onDell Inspiron 537MT ? I'm getting ready to add a 120 GB SSD & use MiniTool Partition Wizard to Migrate Windows 10 OS to SSD https://www.partitionwizard.com/help...from-free90100 If SATA controller is in AHCI mode then I think I can migrate to the SSD as planned, but if SATA controller is not in AHCI mode I don't know what to do!! I'm doing this for a friend & I'm also documenting on my website so anyone else can have info to add a SSD & extend the life of older computer to save $$here's my web address http://shopwilkes.net/comp_help/how_to_install_an_ssd.htm any info will be greatly appreciated

HiI got M91p Desktop (ThinkCentre) - Type 7033D55my SATA Controller Mode needs to be set to AHCI in system BIOS but BIOS is protected by passwordAny solutions?

Read other answers

Hi. My desktop (h8-1080t) is about 5 years old, and is configured with two 1TB, factory-installed HDDs, along with a custom-installed 250GB SSD where my OS (windows 10) now resides. Out of the box, the two HDDs were configured in raid 0. When I moved my OS over to the SSD about a year ago, I changed the sata controller mode in the BIOS from "RAID" to "AHCI." Now, since I'm about to sell my computer, I changed the mode back to "RAID" (my intention was to configure the hard drives into RAID 1, so as to increase reliability for whomever buys the computer; I now realize that HP's bios doesn't seem to support anything besides RAID 0). Anyway, after making this change, my computer will no longer boot. I get past post and the screen is black with a blinking white cursor, as if the operating system isn't there. No blue screen. No text. Nothing. After doing some reading, it seems that I needed to do a clean OS install if I wanted to change the controller mode. After trying to revert back to AHCI mode and even IDE mode, the issue persists.

A:PC Won't Boot After Changing SATA Controller Mode from "AHCI...

Hi: That is correct. You would have needed to install the RAID driver before changing the setting and restarting the PC. Now it is in no man's land. See if you can rectify the problem by trying the info on this link below... https://support.microsoft.com/en-us/kb/922976 If not, you will need to reinstall the OS with the drive controller set as you wish.

this is an ASUS X83V notebook - Setting the SATA operation to 'compatible' mode at installation, Win8 CP installed fine, no hitches. Switched BIOS to Enhanced/full mode and it fails.

I recall this sort of problem from XP installs where tricks were needed to support SATA, but I do not recall this on Seven. Will Win 8 not detect the right controller, fetch the right driver? Do I need to manually force-install, reboot, reselect enhanced mode, and go from there?


A:Are SATA issues like Vista?? Can't operate in full SATA mode

Is this so-called "enhanced" mode switching the storage over to AHCI mode? If so, you have to edit the registry first before being able to do that.

I have 2 IDE DVD drives (TEAC DV-W516D DVD/CD ReWriter, and TSSTcorp DVD-ROM SH-D162C DVD/CD Reader). Teac is capable of 16X DVD writting. My motherboard Gigabyte Z77-D3H has only SATA II/III slots. So I connected each IDE optical drive to motherboard's SATA II slot(s) using IDE to SATA I adapters (1 adapter per optical drive). Windows 7 Ultimate 32bit is running, and SATA AHCI is being used.

My question:

SATA I = 1.5Gbps = 187.5MB/s (adapter capability) is faster then DVD 16X writting = 177.28Mbps = 22.16MB/s.
TDK DVD+R disks tested OK (on other PC) for 16X capability.
Why is Nero reporting of only 2.4X and 4X writting speeds?

A:SATA AHCI Controller, IDE DVD RW slow speed

I believe ACHI mode is used for a RAID setup. You can only run in either mode not both. That might be a large part of your problem. Try switching back to SATA mode.

Hi, bit of a long shot, not sure if anyone will be able to help me.

I remember a good few years back i would always use the latest SATA or matrix / RST drivers and would always update them regularly, I?m pretty sure i have had newer drivers on my laptop in the past than what i have now, i cannot find any though, every time i try to install any of the above they always say not supported on my laptop, the drivers that are currently installed are:

Driver Version:

Date: 29.11.2011

They are very old and would like to be able to use any newer ones that would benefit me, the rest of my laptop is up to date, just not that.

Even when i run Intel software update utility it finds nothing new for it.

My laptop is Lenovo Edge E530.

I am running windows 10 64 Bit Pro

If anyone can help at all that would be great.

A week ago this driver was up to date (per what Driveragent says) 2 days ago, i ran driveragent again and it said i needed to update it. Well ive tried and tried and tried updating it, and it wont update. So, for some idiotic reason, i decided to delete the device and let windows rebuild it. Well, its been a pain in the keester ever since. If i revert it to a microsoft driver instead of intel, driveragent says its updated, but then i go to reboot, it rebuilds itself and reverts itself back to an oudated driver (according to driveragent) How do i fix this once and for all. Ive done several system restores via restore disks. Nothing happens. Please help!!! This is getting the best of me.

The driver it says its using is iastor.sys

Am running a new Lenovo G570 laptop with Windows 7 Home Premium. Attempting to access my IDE ATA/ATAPI controller (Intel Mobile Express Chipset SATA AHCI controller) to check for DMA settings. Getting nowhere, because what I get is a message that tells me it is working properly. No opportunity to see whether or not it is running as DMA or PIO. The computer has Intel Core i3 installed, and the driver was preinstalled when I purchased the machine. Have attempted to rip a DVD, and while it worked, it took a looooong time to load and the result was not particularly useful (short homemade DVD that duped three times!). Is it possible to access settings beyond "working properly" so that I can be sure that the rip/burn process is OK? Help appreciated! Thanks, Jacko.

I was/am trying to solve a BSOD issue and made things worse.
After running memory tests, hard drive diagnostics, sfc /scannow, and not coming up with anything I started to lean towards driver issues.
I used WhoCrashed to analyze my system and it pointed to iastor.sys (intel storage manager driver)
Then I used DriverMax to show me drivers that need to be updated, there were a lot but I started with 2 Intel drivers:

Intel ICH10R SATA AHCI controller
Intel 82801 PCI Bridge -244e

I used DriverMax to download and install the drivers, after updating and restarting my machine it was very slow and it crashes frequently. Takes 5 minutes to boot windows and 30 seconds or more to complete any simple task (clicking on start button, scrolling navigation sliders, opening programs, etc.) and the computer crashes before I can do anything besides open a program. It did have a message that said driver failed to install. I opened DriverMax to rollback the drivers but it crashes while doing so.

I can start it in safemode and the computer is still extremely slow but does not crash. I went to do a system restore to the point before I updated the driver and 7 or 8 hours later is was still on the logging out of windows screen. I restarted and tried again to an even earlier point and the same thing happened again. I then restarted and opened safe mode w/command prompt and ran sfc /scannow and here it is 12 hours later with only 14% of the verification phase done. It's not frozen just m... Read more

I have an Erazer X315 (Machine Type Model: 90AY000CUS) on Windows 10.  The SATA Controller was switched to IDE from AHCI.  It ran a bios update now the machine wont start.  The power will kick on the HDD, and fans will kick on at 150% after 5-7 seconds.  I switched my monitor to the onboard graphics (vga) but still do not get a display (anything). I have removed the redeon GPU and reset the CMOS through the battery and the jumper. Again no display.  I have tried multiple monitors as well.  Im sure this is due to the AHCI being switched to IDE, but I cant return to the bios to switch it back.  Any thoughts? Thanks in advance.

Hey everyone. I hope everyone is doing fine. I've literally rebuilt my entire machine but I think I made a mistake before installing Windows 7.

I should have gone over the BIOS with a fine tooth comb, but I did not. The SATA mode is set to IDE instead of AHCI or RAID and now of course, I can't switch it to my knowledge without getting a BSOD. It means I would have to reinstall the OS over again.

I have been reading up online and did a search here, but didn't find the appropriate thead. I have two questions. I read on a forum somewhere, where an Intel user used a program to change this in Windows somehow. Is there some kind of utility that will allow me to switch to AHCI mode without reinstalling Win7 64bit?

Second question, is it worth it to switch over? I see the benefits are this:

AHCI mode brings 3 main advantages:
Supports NCQ (Native Command Queuing) allowing SATA drives to accept more than one command at a time and dynamically reorder the commands for maximum efficiency.
Supports hot plugging of devices
Supports staggered spin ups of multiple hard drives at boot time

My machine seems kind of slow when accessing data and don't know if this is an issue with the SATA drives being in IDE mode. I got some choppiness in some games that's coming from access data (tested) and that seems weird but could definitely come from SATA drives being in IDE mode.

A:Sata Mode AHCI / IDE

That's weird. I thought Windows 7 handled switching to AHCI mode better than that. Guess it has the same problem as XP.

Anyway, quick answers to a couple of your questions:

1) There is nothing magical about AHCI. About all you will gain is the ability to hot-plug drives. That may be worthwhile if you use an external HDD connected by eSATA. Otherwise, I wouldn't worry about it.

From what I've read, NCQ is only of real benefit in an environment where the disk is being accessed constantly, such as server. Normal desktop users probably won't see any measurable benefit.

The staggered spin-up thing probably doesn't matter either. Maybe it would, if you were running a large RAID (like maybe a 6-disk RAID 10) and had a barely-adequate power supply.

2) Yes, there should be a way to install the AHCI drivers so that Windows 7 doesn't bluescreen on startup. I did it with Windows XP, although it wasn't all that straightforward. I didn't have to reinstall Windows XP, and you shouldn't have to reinstall Windows 7 either.


Just for curiosity, I tried switching my disk controller to IDE mode. Windows 7 booted, but then made me reboot immediately, presumably because it had to install the IDE-mode drivers for the disk controller. On next startup, I re-ran the Windows Experience Index test. My disk score remained exactly the same (5.9) as when I had the disk controller in AHCI mode.

I then restarted, got into the BIOS menu & switched the disk controller back to AHC... Read more

I have just completed a new build using my HDD's from my old computer so I an running Win XP Pro SP3 32-bit before installing Win 7 Home Premium 64-bit.

My HDD are configured as IDE in bios and everything works fine. If I reset the HDD mode to AHCI I only get the windows splash screen and the system restarts.

Searching the archives I found the following from crjdriver :

FWIW I have done some tests running native or standard ide and ahci. On an intel p35 chipset board, an amd 770 chipset board, and an intel 945 chipset board. On each one, native ide actually gave better performance in a benchmark. Not by much however it was faster with both a raptor drive AND a seagate 7200.11 drive. If anything should benefit from ahci, it should be the newer seagate however it did not.

I have an XP + Linux dual boot setup. I booted XP for the first time in months, and it immediately went back to the BIOS boot (no BSOD, only the automatic reboot). Safe mode did the same thing. After experimenting with BIOS setups, I discovered that the problem was apparently triggered by my changing the SATA controller setup from IDE to AHCI mode. Linux is OK with this, but XP apparently not.

Can someone verify this? Do I need another driver for XP? I doubt if the performance gain from AHCI is noticeable (true?) so perhaps it is just as good to keep the IDE mode for both OS's.

A:XP does not boot if SATA in AHCI mode?

my 2 cents: keep IDE mode.

however, the problem can solved by forcibly installing the xp SATA driver while in IDE mode (you must install hardware that is currently not connected). then restart in AHCI mode and windows XP should work.

I installed XP in dual boot mode with Vista pre-installed on a Toshiba Satellite L350-20J notebook.

Since I couldn't find the appropriate files for the F6 process in the Matrix Storage Manager (in the L350 Toshiba driver section for XP, you get an EXE file) to use at xp install time, in the BIOS I switched the SATA AHCI parameter to "compatibility". The XP installation went fine.

Once XP was installed, when I tried to run the Matrix Storage Manager driver, I got the message "This computer does not meet minimum requirements for installing the software". On the other hand, the chipset utility was installed without a hitch.

When I switched back the "compatibilty" parameter to AHCI in the BIOS, the system would not boot properly. It would direct me to multiple choice screen for Safe mode, etc.

Furthermore, EasyBCD gets stuck when I try to define Vista in the Add/Remove entries section.

How can I get into SATA mode at this stage?

I have a company laptop (HP 8530w) with Checkpoint Pointsec HDD encryption and 32bit Vista.
I want to use win7 booted from an external eSATA drive. For that to work first of all I had to remove the internal HDD, because win7 install has already ****ed my system up one time (probably the MBR because the encryption never came up after I installed win7 on the external drive). Secondly I had to set SATA mode to IDE because in AHCI mode it can't be booted on this laptop. (RAID would also work but I didn't want to complicate things).
My question is if I try to boot from the internal drive would it **** Win Vista up or even the encryption stuff? I mean without resetting SATA mode to AHCI (so that i don't have to change it every time I want to boot from the extrnal drive). And that's not even the biggest issue: for now I think I will remove the internal drive every time I want to boot another OS, I don't want to go to IT support all the time.

Basically what i wanted to achieve is to get the laptop to boot from the external drive whenever it is plugged in at home, but boot the company OS Vista at work. It seems it is not that easy.
Do you think it can be done?

Maybe I'm going to buy a SSD to speed up my PC Is it possible to use one of the black sata ports if I enable AHCI. (I don't want RAID, just want to use it like the others SATA ports).

Then should I put my DVD or a harddrive in the black port?

A:SATA that support AHCI and RAID mode only

If you enable AHCI, I suppose that SATA ports 5 and 6 will behave like the other four SATA ports. I see no indication in the M4N78 PRO manual that ports 5 and 6 are on a third-party controller.

On my own Asus motherboard, I'm using AHCI mode. An SSD, a HD, and two optical drives (all SATA) work without problems.

I don't know how easy it is to switch to AHCI mode without re-installing windows with your nVidia chipset. It's not difficult with Microsoft drivers:

Hi, back with another issue on a different computer.

I'm installing Seven on a WinXP machine and completed the install, but forgot to change the SATA setting in the bios from "compatibility mode" to AHCI. Now when I change it, windows gives me bluescreen on boot.

I'm dumbfounded that Windows Seven startup repair can't fix a problem this simple, but it completely failed, wasn't even able to find a problem.

I was thinking it might be easier to just reformat and begin the install over again, or startup in safemode and install the intel SATA drivers... assuming it will let me boot into safemode with AHCI enabled.

Is there another alternative here?


ps. On the other computer (different thread), I'm going to wait till I have several hours of uninterrupted time, in case I need to begin over installing all the windows versions one at a time. I'll reply with any success/failure on that thread later in the week.

A:Changing SATA from Compatibility mode to AHCI

Not to worry - Windows 7 actually already has a generic AHCI driver; it just needs to be enabled before you change the mode in your BIOS.

Microsoft provides a step-by-step guide for doing so, which involves nothing more than setting a single registry value.

and finally when I changed SATA mode to AHCI it saw the HDD but could not start Windows, so I changed it back to IDE and it started Widows as if nothing had happened.
Whenever I shut down the computer and try to start it, the same thing happens, and I do all these steps again.

I also tried to install windows 8.1 on AHCI mode, but the same thing happened again. But this time I had to switch to IDE and then AHCI again.

Also, when I pick restart option, not shut down, there is no problem. It restarts just fine.

Do you have any idea why this is happening or how can I fix this?

Hi everyone I've got a Latitude D820 and I really like it. I'm really interested in getting an SSD to put in this system but I have my doubts. I have been told that SSDs only really like being in ACHI mode but the D820 doesn't have this option in the BIOS. I've also been told that SSDs running in IDE compatibility mode will cause bluescreens and have slow performance.
I did some digging around and discovered that Dell have hidden this option from BIOS setup for the sake of saving time, answering costumer support calls regarding SATA operation and drivers.
So my question is, will Dell be able to release a new BIOS revision with this feature enabled? The D820 is still a capable and i would hate to see it crippled in this way.
Thanks in advance for any replies.

A strange problem, nothing critical, but I found it annoying that my optical sata drives will not boot from a bootable disk when in AHCI mode in Bios. If I switch the drive mode to native IDE then I can boot just fine from either of the Opitcal Sata drives.

I have done some searching and found this has been a problem out for some builds/MB in the past but you would think with a new MB and Sata controller and such this would no longer be a problem.

If you look at my specs you will see the Gigabyte MB. The documentation is fuzzy on the sata ports. There is a setting to put SATA port 4/5 into some kind of IDE support mode. I currently have the slots 0 - 3, used for all the drives. 0 & 1 for HDD, and 2 & 3 for the optical drives, wondering if I use the 4/5 slots for the SATA and set the bios to the 4/5 ide support if this might solve my little problem.

Has anyone else out there run into a similar problem?

A:AHCI mode no boot from sata optical drives

Optical drives to my knowledge don't benefit from AHCI.
You have 2 controllers, Intel and Gigabyte.

1. Install SATA hard drives on the Intel controller and set it to AHCI.
2. Install Optical drives to the Gigabyte controller and set it to IDE.

Even if you did set all controllers to AHCI, double check the boot option and make sure that the optical drives are set as the first boot device.

Ideally, the hard drives take advantage of AHCI, so it doesn't matter whether the optical drive is set to AHCI or IDE.

hi all. i just got an asus a8r32 mvp deluxe crossfire board, and it has tons of options in the bios im not used to seeing. one of them, under storage, allows you to run your sata drives in 'emulated pata mode' or 'AHCI mode.' i have read that AHCI is faster, but what exactly does it do, and how do I get my computer to support it, because everytime I enable it my system reboots and will not load windows. thanks.

I am having trouble installing Win 7 Ultimate x64 on my new Intel 510 SSD drive connected to the Marvell 9128 controller (on my Asus board) in AHCI mode.
Mind you, Windows installed fine on the 510 when Marvell was in IDE mode.
I am usually able to get to the HDD selection-screen, and here I see the Intel 510 drive just fine. Then, I load the Marvell 912x Controller Driver V1.0.0.1036 (downloaded from asus.com - where I made sure to select Win 7 64-bit). I also tried the version - downloaded from some other place.

During the subsequent installation, the setup crashes/hangs at various times. And nothing more happens.
One time I managed to get into Windows after the installation but after one more reboot, that was the last I saw of the Desktop.

I read a guide on how to switch to AHCI controller-mode after having done the installation in IDE mode.
The guide (How to enable AHCI in Windows 7 RC after installation | iThinkDifferent), along with several other guides, talks about modifying the "msahci" entry to value "0" under

This results in the same hang-situation during boot-up - after the switch to AHCI has been done in the BIOS.

Side-notes: Have run Memtest on the RAM for over 12 hours with no errors (also, the system has run stable as heck the past six months on a regular HDD on the exact same Marvell port).

I sooo need your suggestions! I find it so frustrating that I... Read more

does anyone know if it's possible to change the hard drive mode from SATA to AHCI (or even IDE) in the BIOS ?

I can see the hard drive in the BIOS but I am unable to select it to make changes as it's "greyed-out".

I have installed the latest BIOS but that has not made any difference.
Many thanks.

A:Equium L40 - Can I Change Hard Drive Mode from SATA to AHCI?

I don?t have this notebook model but usually SATA controller mode options in BIOS are either AHCI or compatibility.
I presume it is set to AHCI.

Your notebook has SATA HDD so I don?t understand why do you want to change anything. Using AHCI mode HDD can run with ?full speed?.

I am a user of the vistax64 forums and found thread on the 7 forums related to a problem I have. I use vista but I don't think my problem is OS independent. Anyway, I stumbled upon this thread:
Sata Mode AHCI / IDE

A user, Unifex, posted this "Well, that's the thing for Dell Inspiron - there is no separate setting in the BIOS for AHCI. Only IDE and RAID. But, RAID actually corresponds to AHCI, so by choosing RAID I actually get the AHCI BIOS screen and so on"

That is exactly what I want to know how to do. How do you get the AHCI BIOS screen after selecting RAID in the Inspirion 530s BIOS? I am aware this is a very hardware specific question. I hope this is appropriate for these forums. Unifex, if you happen to be reading this post, I would greatly appreciate your input considering your familiarity of this BIOS.

A:Selecting AHCI SATA mode: Dell Inspirion 530s


I believe the RAID option is for the AHCI. There inst a separate BIOS Screen for this option although it may show a few more settings on the BIOS relating to the RAID. If you are going to setup your OS so that it uses AHCI then you will have to download the drivers first or your system wont boot.

For a little more information have a look at this:

Hi, I recently purchased P53s in Windows 10. I've been trying to dual boot with Ubuntu but the computer doesn't recognize the SSD when booting with a flash drive. In bios, I can't find a place for changing the SATA mode to AHCI (no sata configuration). Should I update the bios? Please let me know what to do. Thanks!

Can someone hit me with a link for manually installing the AHCI driver and switching the OS mode for the storage controller.

If I remember right, this is just putting the driver in /sys/drivers, running a script, and making a registry change. Then you reboot, change the motherboard setting, and then install IMSM after the OS comes back up. I don't remember the script, or if it was just a reg edit, etc.



A:change storage controller to AHCI mode post install (win7 64-Ultimate)

Normally this is done in your BIOS, once you have the driver downloaded and installed. When that is done, reboot, go in to bios change settings, save and exit and complete the reboot.

So after I changed to SATA AHCI mode in the BIOS, the main boot internal hard drive shows as a removable device in system tray. So how do I fix this issue, and I did follow the instructions in the Microsoft Knowledge Base article 922976, http://support.microsoft.com/kb/922976
to enable the sata driver first before I changed the BIOS setting. However in the Vista on the
same hard drive in the same computer, with the same SATA AHCI fix done to enable the needed
drivers, the internal hard drive does not show in the system tray as removable. So possibly if
I install the Intel Matrix Storage Manager from their site for this ASUS P5QL Pro motherboard
with a Intel P43 express chip set, known as ICH10, then after a re-boot it may no longer show
as removable. This computer is a 2009 store built desktop that has only one 500 GB SATA hard
drive installed. I had it set in the IDE compatible mode, so that I could mult-boot with XP, Vista, 7, and Ubuntu Linux.

A:after change to SATA AHCI mode in BIOS the drive shows removable

That's not an issue at all, and it's perfectly normal. AHCI offers, on some boards, hot swap capabilities. It's nothing to worry about.

I am confused, as I'm not really that good at computers. Does this update format your computer as I have a lot of things in my computer. Please help, I have SP2.

A:Intel - Storage Intel(R) ICH9M-E/M SATA AHCI Controller Windows update

Hi smalis,Your image shows two Microsoft updates:1) MS Security Essentials virus definition update. (this should automatically update in the background)2) Intel Storage Sata Controller.Neither update will "format your computer" but my recommendation is NOT to download (#2) Intel Sata Controller from the Microsoft Update site. This type of driver from a stability and reliability standpoint is best obtained from the manufacturer of your motherboard or the manufacturer of your computer system (Dell, HP, etc) if it is OEM.

There is nothing to fix, SATA drives are hot pluggable so that is all perfectly normal.
