Coming From XP, Enable AHCI For SATA Drives?
May 11, 2011
I'm coming from win XP and I've got 3 SATA drives currently operating in IDE mode. I am just about to move to Windows 7 Pro and I was considering setting the motherboard to recognize the drives as AHCI. I am going to reformat one drive completely for the OS drive.
My questions are:
1. Will this negatively affect my other two storage drives because they had previously been running in IDE mode?
2. Is there a way to determine whether or not my drives support AHCI at all? (They're all SATA drives bought in the last 4 years.)
3. I intend to run XP mode, will AHCI mode pose any problems for this?

I would like the good and bad about running your SATA drives in IDE and AHCI modes.
I have 3 drives. 1 SSD and 2 normal hard drives.
Does it even make a difference? I have an Esata bracket that I want to run in AHCI mode but how about the normal system and data drives? What is the best way to set up drives?

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.

New i5-8570k with Z77X-D3H build. SSD's & HD's. 1 backup HD is in a caddy (simple SATA connection, its not a raid device) with on/off switch. BIOS is AHCI by default. Installed Win7 Pro x64 then after chipset drivers with mobo DVD. IRST is installed but notes say it should be installed during o/s install. How to confirm AHCI is on? The drives aren't listed in safely remove/eject hardware icon in systray. HD Caddy is useless because hot swap isn't working or on.
Does the new Z77 chipset require the drivers to be installed during O/S install? I tried that with files on USB flash drive but Win7 prevented it because the drivers were unsigned. These are Intel's latest drivers for the Series 7 chipsets. I've tried to confirm whether i have AHCI on or not, 'AS SSD benchmark' detects 'iaStor'. I guess if the chipset drivers must be installed before o/s install then the question becomes "How to install Intel drivers that aren't signed during O/S install". There is no 'ignore & continue' option.

I recently upgraded to an SSD. I moved windows 7 over to the new SSD and re-aligned the partition properly The drive setup is as follows:
2x 500GB WD Black drives in RAID 0
1x 120GB ADATA S510 SSD
In BIOS, RAID mode is enabled. You cannot enable RAID for one pair of drives and AHCI separately. I was assuming disks that are not part of the logical RAID volumes would be set to AHCI automatically. I have enabled NCQ in AMD RaidExpert for the SSD.WEI is 5.9 for the primary disk. The primary disk is the SSD.Other strange behanivour is that the RAID array and the SSD both appear as SCSI devices in device manager, and Windows won't accept the ahci drivers from ECS.

I have the GA-EX58-Extreme Board and have just installed the pre release of Windows 7 7600 64 bit. Normally i have experience to get the BSOD when in staling with AHCI active in bios so i change to IDE mode. Installation went flawless and also the change to AHCI mode on Intel ICH10R controler went normal.
As always i got problem to change the J micron controller to AHCI and of cause i got the BSOD again. I installed the latest R1.17.48.16 driver and tryed again but no luck. Can some tell me what i am doing wrong. ? I have a hardisk and a dvd drive attached to the J micron Sata connection.

Very little, all the parts were shipped here about four days ago and I spent a couple of hours putting them together. I ran into a hiccup when Windows 7 Home Premium would not get past the extracting phase of the installation, kicking up the error in this thread. I began the first install on a 20GB partition, when that failed I tried just installing it on a single partition. When that failed I tried removing all the partitions and just installing on the unformatted drive, in it's entirety (seemed weird but others said they had luck with this).Testing Methodology:
At the end of each attempted solution I tried to install Windows again.My keyboard is a USB keyboard. All of my boot testing is done with a bootable USB that I have running MS-DOS 6.22. What I Have Tried:Solution 1: First I went into the bios and changed the SATA controller from AHCI to Raid SATA Result = FAILEDSolution 2: I tried burning OEM Windows disk from Microsoft to an iso at the lowest speed possible for my DVD burner (4x).Result = FAILEDSolution 3: At this point I had created and deleted so many partitions I was concerned it may be having an effect on the install. So I went to Samsung's website and grabbed their HDD utility tool. I figured let's kill two birds with one stone and test the drive while also restoring it to it's original state. So I did a low level format and then ran the HDD diagnostic. All came back with no errors. Result = FAILED
On to memory...Solution 4: I downloaded Microsoft's Memory Diagnostic Tool and let it run overnight. It returned no errors. So I decided to use MemTest86 4.1 and let it run for 10 passes, I did find errors then. As of now I am running each module of memory one by one to determine if it is a problem with them or the sockets on the motherboard. So far I have been unable to reproduce the errors I got when both modules were running together. As a precaution I double checked the motherboards specifications on the socket order for memory, all is to specs. Result = [PENDING]What's Next:After my current memory test ends, I plan on checking my BIOS to see if the correct memory speeds were detected in the auto detection. If at that point I'm still unable to reproduce the memory errors, I'll put both memory modules back into the system and run the testing again to see if I can reproduce the errors I got the first time.

In the BIOS on a laptop the disk choice can enable SATA as IDE or AHCI.
If I chose IDE do I actually lose any disk performance -- having IDE makes it easier to have Windows XP as a dual boot system without having to hunt down all the SATA drivers and slip stream an XP disk.
Remember this is a LAPTOP not a desktop so disk performance won't be that great in any case.

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?

I have just fitted a SSD drive in my computer windows 7 64 bit system, when I installed windows onto the new SSD I just unplugged my old hard drive and fitted the SSD and just installed windows 7 and all worked ok. But after the new install was working I was told I needed to make a change in the BIOS to alter the settings from treat Sata as IDE to treat Sata as AHCI. I did this and all was ok with the new drive the installation worked and the new drive is running ok.
But now I have since read that I should have made the bios change before installing windows nad should not be done after the install, So do I need to reinstall windows 7 with the bios changes to treat sata as AHCI before I install or will it work ok it seems to be ok but im not sure now. I was also under the impression that I could still have my old hard drive fitted and just select the hard drive I wanted to boot from as the computer started, I wanted to do this so.
I could still has access to all my old stuff if I needed it. But now my old hard drive will not boot until I change the Bios back to treat Sata as IDE, so is this not going to work or will I have to change the bios each time I need access to my old drive. Also I have an Asus P6T SE motherboard so can I plug the SSD into any Sata port or is it better to plug it into number 1 if so how do I find which one is number one.

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.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.

Went into the registry, and changed the Start Value of msahci to 0. However, when I enable AHCI in my bios, Windows 7 won't boot. It freezes and then my system restarts.

Okay I plan on doing a clean install of Windows 7 on my laptop. I have an SSD from crucial.I know that I need to enable AHCI BEFORE I start the installation of Windows 7...correct? I saw this Intel website in regards to AHCI.Intel Rapid Storage Technology” Configure the BIOS for RAID or AHCI on an Intel Desktop Board.I know that my laptop has a chipset that supports AHCI."Enabling AHCI or RAID after installing the operating system is not recommended or supported when a SATA hard drive is the boot drive. Enabling AHCI or RAID after installing the operating system might cause an immediate blue screen with an 0x0000007b error code, followed by a reboot. If you use AHCI or RAID, enable them before installing the operating system.".it looks like enabling AHCI is the absolute last thing I should do before installing Windows 7. As in this is the routine I should follow.
1) Back up any drivers/files/etc that I need
2) Insert Windows 7 Installation Disc
3) Close out of pop up install window.
4) Restart Laptop
5) As laptop is restarting enter BIOS
6) Follow Intel's step by step guide for enabling AHCI
7) Change system to "Boot from DVD Drive"
8) SAVE new BIOS Settings....EXIT
At that point my computer should REBOOT and this time it will do so from the DVD drive and Windows 7 installation screen will appear correct? OR am I missing something? Do I need to do anything in Windows 7 itself before I do anything with the BIOS?

i have an m17 r2 alienwAre laptop.in the bios menu the sata option HCAI is selected but when the comp boots it says no operating system is found when booting for bios sata option RAID it runs fine. But the comp should be on HCAI in order to run features that a specific to that computer . I have tryed reformatting but in HCAI it on finds the second of 2 500g hard drives but the partition with the boot is on hdd1 not hdd2 . Boot up again with RAID it finds both and and I can reformat have tryed to reset the registry and have tryed using drivermax to find out if I'm missing sata drivers I've also tryed reinstalling my bios from the dell

I'm attempting to install a retail copy of Windows 7 Ultimate 64-Bit (VPCEB15FM) or "PCG-71312L" on this laptop. However, this message appears: "A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now." The problem is that I cannot find the Intel 5 Series 4 Port SATA AHCI Controller drivers for Windows 7 64-Bit to put on a floppy or USB drive. I've combed the Sony website and Google and the only Intel 5 Series 4 Port SATA AHCI Controller Drivers that can be placed on a floppy or USB are for Windows XP. Without the TXTSETUP.OEM, I'm dead in the water! The 64-Bit drivers (INDOTH-00215023-0042.EXE) are for an already installed Windows 7. BTW guys, the the BIOS settings on this laptop is as anemic as it gets, so there is really no way to optimize there..

I just changed my disk setup from:
1 SATA HDD Primary OS Disk
2x SATA HDD Backup Disks in RAID 1
TO:
1 SATA SSD Primary OS Disk
1 SATA HDD Backup Disk
[No RAID]
Everything worked great, no problem. So, since I don't have a RAID array anymore, I decided that I could change my BIOS setting to AHCI instead of RAID. I have a Gigabyte GA-P35-DS3R v1.0 mobo.
These are my steps:Settings > Integrated Peripherals > "SATA RAID/AHCI Mode" = RAID
--> Changed this setting to AHCI Reboot Windows Start screen shows up, but as the color orbs are spinning into focus, BSOD and immediate restart Repeated reboot several times, same outcome
Next Step:Launch BIOS settings Integrated Peripherals > "Onboard SATA/IDE Ctrl Mode" = RAID
--> Changed this setting to AHCI Reboot Windows Start screen shows up, but as the color orbs are spinning into focus, BSOD and immediate restart Repeated reboot several times, same outcome
Switch both settings back to RAID, reboot, and Windows starts up just fine, no issues.
What am I missing? Why can't I set it to AHCI mode without BSODs?

i'm working with a new pc build that uses a 60 gb ssd for its boot drive, and which is also reusing some "old" sata hdds for storage.
at the time i installed windows 7 ult 64, i had only a new ssd plugged in, and the bios was set to ahci mode. the installation went fine and i was able to boot into windows afterwards without issue.
then, i connected a wd caviar black sata hdd to use as storage, with the ssd being the boot drive. with both of them connected, windows will not get past the starting windows screen.
i made this video of the program before i understood that it was a drive controller issue: startup problem - Internet in it, you can see that windows boots fine in ahci mode with just the ssd plugged in, but that when the backup sata drive is also connected it doesn't get past the starting windows screen.
for the record, this caviar black hdd was my previous boot os, and it also has a windows 7 install on it (which i've renamed the base folder of), but it is not booting from that hdd. also, i have tried the same thing with other "old" sata hdds that do not have any previous windows install on them, and the result is the same thing which is shown in the video.

I successfully installed Windows 7 64bit in AHCI mode on a PC with 3 new 3TB Western Digital WD30EZRX Caviar Green hard drives.Then I installed "Intel Matrix Storage Manager Driver [v8.9.0.1023]" & as soon as Windows restarted after installing it, Windows would not boot, & will now only boot in IDE mode.In IDE mode I have to do a system restore to the point before installation of "Intel Matrix Storage Manager Driver" to be able to boot again in AHCI mode.

as some of you may know ive had a buggerload of problems with my LaCie external HDD, which, slowly, was put down to a faulty drive controller. Having taken out the HDDs held within, ( 2 samsung 500GB HDDs )
ive attempted to get 1 of them working as an internal drive. Ive connected it to the power and sata cable, but when i boot i (perhaps obviously?) am not getting any connection whatsoever. is there something i need to do in bios or something to get it to work? what am i doing wrong? (because invariably i AM doing something wrong).

I am currently running Ubuntu 11.04 on my HP (DV5 1110em) laptop from an external USB 2 Buffalo ministation hard drive, I have noticed my machine is equipped with an E-SATA port. Would using an e-sata external hard drive be any faster that the usb option ?.

My pc had suddenly decided to not recognising any of my Sata drives. Win 7 32 bit, 4 gig ram, asus psn d motherboard,ati sapphire 1g pci card, 1 250g western digital Sata drive 1 x 1tb seagate hdd. Sata DVD drive
Yesterday my pc froze up while surfing the web, so reset it and that where the problems started
It only recognised one of the hdd then wouldn't boot got a bsod uncountable boot volume. So opened up the case to check if the cables where loose, nope, so decided to run a repair via the recovery console. Didnt detect my o/s at all ask me to install the correct drivers grrrrr. So stripped the pc down swapped the Sata cables to see if that was the problem, no joy at all would only find one Sata drive and DVD drive. Then it wouldnt recognise any of them, so swapped out the Sata DVD drive for an IDE drive. The booted up nothing bar the DVD drive. Have now come to a cross roads don't know what else's to try. Managed to boot via a USB drive with Linux and everything system wise, pcu, gpu etc works, but still no Sata drives.
Done some digging online and some ideas are not a big enough psu, faulty Sata cables, but swapped in an IDE hdd and nothing again.

Just built a moderate spec gaming PC from scratch, and all has went according to plan except when I try to install Windows 7, my hard drive won't show up. My new motherboard doesn't have any IDE slots, but I only have an IDE hard drive. I am using a 'Pluscom Serial ATA PCI Adapter' to connect my hard drive to the computer as it has 1 IDE slot on it. I don't have a disc for drivers and don't know where to start. I am running Ubuntu on it at the moment so I can download any drivers I may need.

I've been reading about issues with people having problems with their SSD's not being reconized by Windows 7 Ultimate.but my WD 600gig STAT III Raptor is listed as a SCSI as well. I assume the problem is with my Marvell Driver.I bought this 60gig OCZ Vertex 3 SATA III drive for a Boot drive and had a pain installing drivers for it on a clean install of windows. I plugged it, and my WD Raptor both into the 2 SATA III ports that I have on my ASUS Rampage III MB. I set the Drives to ACHI not IDE. Tried to install Windows, had to force windows to accept the Marvell Drivers...but finally got it installed.Now Im stuck with the OCZ SSD and the Raptor both at SCSI speeds...not able to get them reconized my Windows 7 Ult as SATA drives.Should I try uninstalling the Marvell and JBMicron drivers and let Windows try and install drivers that will work? Funny thing is, I know that windows is reconizing the SSD as a SSD because of the Disk Defrag has been disabled on it...and was able to get some info off the drive via Intels SSD toolbox....OCZ's tool box wont reconize it unless you use Windows drivers. I had to install the Marvell Drivers to install Windows, Windows wouldn't reconize either drive plugged into the SATA III ports.I've tried bout everything, even tried the reg. fix via the Windows Helper with no luck.

I want to put my old hard drive that has files and was used with windows vista and put it into a new windows 7 laptop. Is there any overlap or any config problems I can run into doing this? Or do I just put it in and the old files should work and all i have to do is update some drivers from vista to 7?

I updated the SATA AHCI controller from device manager and rebooted. Shortly after I noticed disk drives F:, Z:, and X: are gone. No big deal I'll just repartition right? No they aren't showing up in Disk Management? The driver I installed I got from gigabyte it was a preinstall driver for ahci. I just installed windows 7 64 yesterday to a Samsung 830 256gb and it was working fine maybe I shouldn't have messed with it. C: drive is working fine just the other 3. Should I roll the driver back? System restore? Did I install the wrong driver?

So recently my desktop PC has been freezing at random times, and then sometimes restarting after not responding for a couple of minutes (no BSOD, just restarts as far as I've seen). It sometime freezes as soon as I turn the computer on, while Windows is loading, and sometimes it will start freezing after an hour it's been on. Most of the time it will just freeze for around a minute, and then unfreeze, but sometimes it does freeze and then restart. By freeze I mean everything, mouse included, and ctrl+alt+delete doesn't work.Also at bootup sometimes, it will fail to detect my SATA hard-drive and hang at Detecting SATA drives at the bios screen. This will be following by a disk read error.This problem started occuring a couple of weeks a go, so I reinstalled Windows 7 and it worked fine after that.
