Moving From IDE To AHCI?
Nov 26, 2012
I recently installed Windows 7 Home Premium on a new blank SATA hard drive which I had formatted using the default settings under Windows XP Disk Management.Prior to installing Windows 7 on this PC, I disconnected my other SATA hard drives to preclude any issues during formatting/installation.What I would like to know is whether changing the BIOS disk access mode from IDE to AHCI will impact my ability to access my old hard drives (once I reconnect them)?

I have an Asus Rampage IV Extreme Motherboard and have Windows 7 Installed on a 96gb kingston ssd.
I now bought 2x 256gb Samsung 830s and want to run them in raid. If I set my RAID in bios, I cannot boot into my kingston ssd, it blue screens. If I set it to AHCI I cannot run my ssds in Raid.
I can do a fresh install on the ssds but how do I move my programs and data over? BTW.. I have Norton Ghost 15 which was provided with the Sammy 830s...

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.

anyways, my main drive is a RAID 0 with Vista x64, but I have a second HD that is a SATA 250GB, which I installed Windows 7 on. The only way I could get install to work was to switch my BIOS to IDE mode rather than RAID. I would of course though, like to be able to access my Vista drive from Windows 7 (and more importantly, not have to switch between IDE/RAID mode at all in the BIOS, it's a pain).
Now, the one odd this about this all is that the drivers I have for Vista (x86/x64 drivers) for this mobo's RAID controller WORK when loaded on installation to identify and install to the drive, but seem to not load or not work in any way once the first reboot on install occurs. Maybe this is because I installed from within Vista x64, though.
(Incedentally, my motherboard is an M3A Asus, using ATI's SB600 for a RAID controller)
I've tried loading the drivers from within Windows 7 while in IDE mode, but the install program won't let me. At first it didn't allow because of version restrictions, but then I altered the ini file to get around that, but it encounters some sort of error when installing and quits.
Any help that can be offered, would be grateful. I realise it's a beta and not a real release, so I can get past the BSOD from my odd setup, and I really am enjoying playing around with it so far. Very very impressed.
Edit: Just in case anyone thinks of suggesting me to right-click the inf file and install that way, already tried, won't allow for it.

I recently swapped out my motherboard for a Gigabyte GA-970A-UD3. I was trying to overclock my CPU and after a crash and CMOS reset I was no longer able to complete WEI. This was fixed by reinstalling the BIOS firmware but when I ran WEI again, I was now getting a 5.9 score for my SSD (OCZ Agility) when it was previously 7.2.
Now I can no longer get Windows to use the AHCI driver (neither MS nor AMD) for the drive. I am running in AHCI mode but the driver being used for the SSD is a generic "disk drive" (disk.sys and partmgr.sys). When I try to update this driver, it tells me I am using the latest one; it also does not let me manually select the AHCI driver.
After multiple attempts at switching back and forth between IDE and AHCI in the BIOS, uninstalling and reinstalling AMD AHCI drivers, nothing changes. Still the same 5.9 WEI score and generic driver.

i have an ASUS M5A88-M motherboard, and a Western Digital WD2503ABYX HDD. i am trying to make that drive work in AHCI mode, but when I try, the disk won't boot. i think the HDD is AHCI compatble, tho not certain. i went into the registry to set a value=o for the relevant AHCI parameter, but no luck. if i need a full re-installation of Windows 7 64-bit, does it prompt me along the way to set the mode to IDE or AHCI?.

Is there any real noticable benefit from having a SATA mechanical HDD use AHCI or IDE? Also, if there is any benefit, is it related to the rpm speed that the drive is capable of?I keep reading conflicting reports on this, some say AHCI is best, others say there is no real difference unless the disk is an SSD.I am about to do a clean install of Windows 7 on a laptop 5400rpm mechanical HDD so thought I may as well set the mode before proceeding with the install.

I recently purchased a HP 8440p laptop with Windows 7 Pro. installed. I dicided to partition the drive and install XP-Sp3 on the newly partitioned drive. Before I could load XP I had to change the configuration to IDE. Once I did that all went fine. Now in order to run betwwen OS's I have to set my configuration AHCI for W7 and IDE for XP.
Is there a better way of doing this beside alway re-configuring the bios for AHCI or IDE?

I have found on 4 different boards if I install in AHCI mode, Windows 7 seems to "find" the drivers for running in AHCI/RAID mode at install. If I install in IDE mode, it does not and I have no option to switch to AHCI/RAID if needed. In the past you had to press F6 (or whatever) and install them from a floppy. I think this is no longer the case with Windows 7. Can anyone confirm this. I don't even have a floppy and never will. I will install in AHCI so I have the choice in the future. Is there any down side to doing this and am I right?
Also - I know there is a registry "hack" you can use to boot into AHCI after installing in IDE but why does everyone not install in AHCI so they have the choice? Am I way off here? Are you planning to install in AHCI to have this benefit?

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.

me as the most of you is using Windows 7 with so much fun! I do have a little problem,don't know why actually,this is why i'm here asking for help. First of all here is my hardware configuration:
Asus P5Q PRO (latest bios,waiting if Asus is ever going to release the EFI also for my motherboard lol just like happened with P5Q Deluxe,anyway).
In bios options if I select AHCI i get faster performance and system responsiveness,but from time to time,it could happen anytime,i get complete hangs up so i have to hard reboot my pc. I tried EVERYTHING,also Intel sata ahci latest driver for my motherboard and nothing works. This happens with both 32 and 64 bit of Windows 7,and it doesn't seem to happen if it's set to IDE (which definitely makes my computer less responsive). Thanks in advance to anyone that will help me
I'm beginning to thing that it's the hardisk getting insane,it's the oldest hardware component in my pc now.

So I installed win 7 on a new WD 2TB Sata3 drive, I enabled AHCI before installing. I have two hdd which I use as storage, but after the reinstall only one of them show's up in my computer. I can see the other one on device manager. Does this have something to do with the AHCI? Never enabled it before now.

I have a SSD drive & want to use the AHCI Mode & Native Command Quening from Windows 7 Pro X64. I performed the Regedit by setting the START paramater in the registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesmsahci from "3" to "0" - and then making the switch in the BIOS from IDE to AHCI. Windows still would not load! The Bios screen would not load Windows 7.I have a Gigabyte GA-EP45-UD3R Board that has a Intel P45 Chipset & I installed the latest Intel Sata drivers before I tried the change. I had to use my Acronis True Image program to get Windows 7 back up & running.My Board has 6 Intel Sata ports & two Gigabyte ports on the board. I don't use the Gigabyte ports & they were left in the IDE mode in the Bios when it failed.The Bios screen loaded differently but failed as I said to load Windows 7.If I perform a clean install will Windows 7 load & install in the AHCI/Native modes with the bios setting to AHCI & not IDE? I have the SSD for programs & a 1TB HDD for storage & backup.

I have a new computer. When it boots up, I see AHCI Bios not installed. I do not know much about the workings of a computer. What does AHCI Bios not installed mean? My computer runs on Windows 7 and so far it seems to work just fine.

Im tryin to get my 64GB Mtron SSD runnin with Windows 7 but I can't get it to show up in the installation process. It shows just fine in the BIOS, in device manager, in My Computer and in Windows Disk Management, in fact I can even use it as storage but for some reason It will not show up as a disk to install Windows. I have tried as IDE in BIOS and AHCI and in AHCI mode it will not show up in the BIOS at all or anywhere, I can only get it to show in IDE mode. It has been fully formatted and has had Windows 7 on it here recently (had to reformat due to some speed issues). Does anyone know a way I can get Windows put back on, preferably in AHCI mode cause Im stuck with a Thousand dollar drive thats good for storage only
My board is the Gigabyte GA-EP43-UD3L with BIOS F8 which according to their site is the latest one. Processor Q8600 and 4GB of OCZ Flex RAM...

I'm trying to do a startup repair of Windows 7 x64 on an SSD but can't boot from the CD-ROM while in AHCI mode. I have set CD-ROM at the top of the boot order in BIOS but this is just ignored and the computer boots from the SSD with the knackered version of W7x64. I read somewhere that when in AHCI mode, the BIOS boot order may include "CD-ROM" but it's not the real device anymore. I tried looking for the CD-ROM by its manufacturer name in the list under Hard Drives but it's not there either.So just how do I go about booting from the CD-ROM in AHCI mode? No problems booting if I set the BIOS back to IDE mode, install Windows 7 and then do the registry hack to install the AHCI drivers, but I'd like to be able to boot from the CD-ROM in AHCI mode.
P.S. I have a Gigabyte GA-MA78GM-US2H motherboard and am using the latest BIOS version (F9D)

This happened when I was booting today after turning it of last night after using it successfully since I bought it.The AHCI Drivers are corrupt.Windows won't load, it is stuck on the load screen.Trying to repair windows using the various F8 options doesn't work because they won't load either.Even the recovery partion won't load, it's stuck on the Acer E Recovery screen "please wait" and it is stuck for several hours on this.Now, in BIOS, when I change to IDE mode, it will load the various F8 options like trying to fix windows, but the problem doesn't solve itself. Also, the recovery partion does load, but it only gives me an option to install everything to factory settings, not just reinstall windows. However, Windows 7 won't actually boot on IDE mode, so I can't actually get into Windows 7.Therefore, my AHCI drivers are corrupt while the IDE ones are fine. How do I install fresh AHCI drivers to fix my corrupt ones from a USB stick? I do not have a windows install disk, it is all on the recovery partion/recovery disks

My motherboard is a Gigabyte Z68XP-UD3 Revision 1.3, my OS is Windows 7 Professional 64 bit, my HDD is a Seagate 1.5tb, and my SSD is an OCZ Agility 3 60gb.
So i was using Intel Smart Response technology with my SSD for SSD caching, everything was pretty much working fine. The other day i flashed my bios using @BIOS without properly disabling my smart response configuration, which i probably shouldn't have done and i won't do again. When i rebooted, Intel Rapid Storage technology was acting up and when i tried to open it, it said "IAStorUI.exe has stopped working". After that, i uninstalled the program and tried to re-install it, but during the install it said "This computer does not meet the minimum requirements for installing the software." After a little research, i found out that it meant that my bios was set in IDE mode instead of ACHI mode. I am not sure what the mode was before i flashed my bios, but it was probably some sort of raid that it used for SSD caching. When i went into the bios and switched from IDE to AHCI, windows would blue screen after performing a few seconds of the boot logo. I switched back to IDE, and did some research to find out about the "Start" registry in HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesmsahci. I switched that from 3 to 0, and windows was able to boot into AHCI mode and automatically got drivers. Then, i tried re-installing Intel Rapid Storage technology. It was able to install, and i rebooted my computer. It blue screened again on the same part of the boot logo as before. I had to switch back to IDE mode to get it working again. Then, i got new chipset drivers from Intel's website, which didn't help. The registry that i changed is still set to zero, but it just won't successfully boot with AHCI like it did the first time i changed the registry. I am very stumped and i dont know what i could do to make it work like it did before i flashed my bios. My friend recommended that i should reinstall windows, but then i would have to go through the trouble of getting everything back and i think there should be some way of doing this without reinstalling the os.
The bottom line is that windows blue screens when the bios is in AHCI mode, even though i have the registry that should fix that and that did fix it on one boot set to zero.

I'm trying to install the Windows 7 32-Bit upgrade on my Dell Inspiron 1721 laptop and I get an error that says that I need to update my ATI AHCI Compatible RAID Driver. I went into the Update Device Drivers as suggested in the instructions and tried to upgrade that driver, but it says I have the latest driver for it. So I tried restarting my laptop and ran the upgrade setup again, and got the same error message.
Any ideas on what I need to do to get it to upgrade? I tried searching all over and can not find a newer version than what I have (2.5.1540.48).

I want to install Windows 7 on a clean drive.... but I cant even get to the install options, because the drive is not recognized when i turn on the machine. It stalls, even before I can get into the BIOS settings.I need to manuallly disconnect the drive > then change back to IDE mode inside the bios and now I am able to install Windows.The funny thing... I have a backup image of a running Windows 7 installation and if I copy it onto the exactly same drive it runs without problems in AHCI mode another weird thing.... i already installed Windows 7 in IDE mode and thought that maybe later, once the installation is done i could switch back to AHCI.well, same thing.... once ahci mode was enabled in the bios, the drive was not recognized anymore.i also tried to install the chipset drivers from within windows and got a "the system does not meet the minumum requirements."

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?

I am trying to upgrade from Windows Vista 32 bit to Windows 7 32 bit but when booting from the upgrade disk it has problems finding my HDD's and says that windows cannot be installed on them once found.
When choosing a clean install from loading the disk from within Vista it starts to install and then when it restarts it brings up a blue screen saying that windows cannot be installed and is I have installed any new HDD's or controllers then on uninstall them.
When trying to upgrade at first it was complaining about the ATI ACHI Compatable RAID controller not being compatable but now it starts to do the install and then on restart it does the same as the clean install.

I have a PC that is all SATA, including the DVD drive. I prefer to set the SATA controller for AHCI for the bit of extra performance. However, build 7000 will not install from the DVD drive set like that. So I changed the SATA controller to IDE and was able to install build 7000. I then manually changed the SATA driver to AHCI, rebooted and changed the SATA controller to match. That works, of course. With build 7057, however, I was able to perform the install with the SATA controller set to AHCI. A nice improvement.
I also noticed two other things. The magical 200MB hidden partition is now 100MB, and I think I saw a speed improvement copying HDD to HDD. At one point I saw 130MB/sec copying back files to the C: drive (new 500GB Hitachi) from the V: drive (year-old 750GB Seagate). This PC has an ancient 3.2 GHz P-4 on a new motherboard.

I need to reinstall my Windows 7 Ultimate 32 bit O/S if I wish to use the AHCI setting for SATA disks?I installed the O/S with the BIOS setting for SATA at ATA then changed it in the BIOS after install. Unfortunately, the PC will not boot with it set to AHCI for SATA but changing it back to ATA gets it to boot.I thought that from Vista onwards the SATA setting in the BIOS could be changed after the O/S had been installed, perhaps not ?
