AHCI Mode Stopped Reconizing Hard Drive
Oct 3, 2012
If the BIOS setting for the hard drive controller is AHCI it will not recognize the drive. (This was the default setting in the BIOS), If changed to IDE mode it recognizes the drive but come up with an "No operating system detected" message. If the hard drive is installed in a second lap top it works fine. If another hard drive is installed it works fine in AHCI mode. Only the combination of the original hard drive and the original lap top wont work.

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.

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.

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 have had an expensive time with my computer recently but i am now beyond the brink and turning the tide of war to my favour.I have recently kitted my ailing PC out with a new SSD for the OS install.This is working great; i have just tonight had to plug in a brand new GFX card for my gaming pc.(My GFX card burned out due to overheating, so i have now got a new case and proper cooling)Basically, my secondary hard disk (Files Storage etc) is not working, when plugged into my sata port my computer hangs at the Windows Loading screen, also i cannot get into the BIOS.If i unplug the hard drive (Not SSD, 500GB Hitachi) my computer boots in 14 seconds, and the bios works fine.I have concluded my secondary hard disk may be broken.if i can fix it as i can barely afford to buy a new one (even knowing they are cheap).Basically if it had broken i would expect my PC would say so, seems to me that it is just waiting for a response and sitting around for hours to get it

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?.

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)

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.

First thing, my build:
Board: Gigabyte GA-P55A-UD4
CPU: Core i7 870 @ 2,93 Ghz
Graphic: Sapphire AMD Radeon 8670 Mushkin 2x2Gb Red Culvert Kit @ 1600Mhz CAS 6-7-7-18
Seagate 320 GB SATA II HDD + WD Caviar Black 1TB SATA III HDD
Running: Windows 7 Ultimate
Trying to install: Windows 7 Ultimate
PSU: LC Power Arkangel 850W
I have Windows 7 Ultimate installed on my 320 Gb HDD and everything is running ok. I just bought a WD Caviar Black 1TB SATA III disk and I want to install Windows 7 there, since the disk is faster. Here's what happens. When I connect the disk (it is connected GSATA 3 connectors), the disk will be recognized in bios and in Windows, but wont show under My Computer. I figured it must be some software bug so I formatted the disk in diskpart (clean format) and installed Windows 7 on it. At that time the GSATA 3 interface was set to IDE mode. It ran fine but after installing a big batch of Windows updates, the system hung at windows startup screen. After restoring the system to a previous state (i.e. before the updates), the system booted up normally.
I didn't know what was wrong so I formatted again, and this time I set the GSATA 3 to AHCI mode, since I realized this is a better option. When installing in AHCI mode, the computer expands the windows files but when the system is restarted, I get a BSOD (code Stop 0x000000B4 video driver failed to initialize) at Setup is updating registry settings. I really want to use the AHCI mode, but I cant get the system to work in IDE either so its really a bugger. I have no idea what could be causing this as the system works fine when using the other disk. Can the BSOD be caused by the HDD? Anyway, I really want to start using the disk. I have tried installing Windows 7 from a dvd as well as from a USB key.

I changed the appropriate setting in the registry. (msachi > start: 0) Then I changed the setting in my motherboard and Windows froze upon starting up, and my system rebooted.
The thing is, I changed it to AHCI before. It worked fine! I then switched back to IDE while trying to fix a problem with eSATA detection (turned out to be a faulty cord), Now I can't switch back! Sigh. I really would like my eSATA to be plug and play.

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.

My dad's hard computer crashed, and we've spent the better half of 12 hours trying to recover about 30 gigs of music off of it. The problem is that the Windows repair stuff that came with our Windows 7 Ultimate isn't helping AT ALL, neither is repair disks, or any other junk that you can think of (and believe me, we've tried it all). When we try to boot the hard drive we get a "Error Configuring System" message, and when we've tried to run Safe Mode by holding f8, it doesn't allow us to. Now, we've also tried running an alternate boot source from the BIOS menu, then holding f8 to see if it'll give us advanced BIOS options and allow us to get to safe mode that way... but to no avail.

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.

My motherboard is ASRock m3a770de. I built my machine 3 days ago. I have one Hiatchi 500gb internal HD, and one 1TB external HD.I am running Windows 7 x64 Ultimate Edition.After building my computer three days ago, I installed windows, and my external was not being detected through eSATA in the BIOS or in Windows "Probably need to install drivers" I said.So I put in the CD that came with my motherboard, and installed the AMD All in One Driver that was on it. Restarted, and hey, my external was showing up.Today, after installing SP1 (not sure if thats what did it), my ext hd was no longer showing up again. I reinstalled the driver on that CD. Now, I'm not sure if it even installed the first time, because it said it was currently uninstalled through the ATI catalyst installation program. But it didn't work this time. I'm not sure what got it to work the first time. But my eSATA drive was being read in IDE mode for three days. When trying to get it work the first time, I did plug it in via USB to see if it would work, maybe that had something to do with it working the first time?
Anyway, I changed my registry to start up in AHCI mode, and then went into my bios and changed my storage config to AHCI. Upon booting, windows would not load with my external HD turned on (anybody know why?), but loaded once I turned it off. Windows then installed AHCI drivers, and upon restarting, both hard drive, external and internal, were being detected as removal storage.Why can't I get my external HD to be read in IDE mode through eSATA? IT doesn't get read through the BIOS or Windows, even if i scan for new hardware.EDIT: sigh, now when I just went to reboot, it wouldn't load windows when my external hard drive was plugged in. Windows loaded when I unplugged it. Windows detected it when I plugged it back in.

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.

After trying to scan my computer with tdskiller (I believe its called) to remove some viruses, I was asked to reboot. When I did, my backround desktop picture turned black, files seemed to be missing from my desktop and a window poped up scanning and telling me how many errors I had. Shortly after I got about 20 error pop up messages. I rebooted my computer and more files were missing to the point all I had was recycle bin, and two other programs.
Now the computer runs only in safe mode, No matter what I do (pressing f8 - start in normal mode) nothing works. I cant get internet access, and worst of all, I cant even system restore or even recover it back to to the malfunctioners option due to errors. I am stuck and do not know what else to try.
Ive tried the repair option in dos aswell and it just keeps me in the "Loading window files" screen, as I left it there for nearly four hours im guessing that was not going to work.

This week, I encountered the following strange problem for which I haven't found a final solution so far, though I have found some bandaids. But having a complete solution -or at least a reason why this problem occurs- would be great:I have a working installation of Windows 7 Professional x64 in UEFI mode. The main disk, SSD #1, contains the following partitions (using GPT): ESP, MSR, system, data. An additional disk, HD #2, with a single data partition (using MBR) is also attached to the system. With this setup, everything works fine.Now, after adding another disk, HD #3, to the system -my old system disk (bootable, using MBR, one active primary partition and an extend partition with three logical disks)- Windows will no longer boots completely: The boot process begins, the Windows logo is shown. Then, a message is shown in text mode "Windows is loading files" with a loading bar. After a while the boot process stops and I am dropped into the EFI shell. After removing the offending HD #3, Windows boots normally again.
I tried removing HD #2 and only attaching HD #3 together with SSD #1, but this yielded the same problem. Using SSD #1 by itself works fine though. Booting from a Linux live-cd works without problems. All disks and partitions are found and can be mounted. There, I erased the disk signature from the offending HD #3 and now Windows was able to boot and also found all disks and partitions correctly. But after a reboot the same problem reappeared

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.

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.

I have a hard drive I want to backup to a 64gb flash drive and then restore it to another different hard drive than where it came from. I have windows 7 and office on my laptop and I want it on my desktop pc. There isn't close to 64gb of info on my laptop so it should be fine even though the hard drive says I have 160gb. It is all free space except for those programs.

I turned on my PC and the monitor showed that there was no signal and went to power save mode. I checked DVI leads - all ok. Tried a few things as this has happened before and realized the BIOS was not loading or the signal was not getting from machine (via graphics card) to monitor. This has happened before and a CMOS reset has fixed.I reset CMOS and could then load BIOS. However Windows would not load even after making sure RAID and all other BIOS settings were as they were before. I tried a few times and did a system restore and loaded last known working profile. Now Windows starts to load and I get to the multi coloured dots forming the MS Windows symbol and it looks like it is about to load, but when the screen goes blank and the machine restarts - this loop continues unless I boot to safe mode.I also removed all usb devices and tried - same result.So, I have tried a number of settings, a system restore, and I tried some other things that seemed to fail as windows said the machine would not start properly.I am now going to boot into Ubuntu to see if that works and that may rule out the gfx card, I will report that back. I will also boot without the keyboard and report that too.

So, I have a i7 2600K system with a solid state disk as the boot drive, and an older (c2008) Samsung Spinpoint F3 500GB drive as the data drive for programs (that I deem as not worthy of the quick load times). The hard drive has given me some errors over time, and I bought a hard disk to replace it (a Hitachi 1TB). The issue I'm having is that the fact that Windows 7 puts a small (100MB) partition on the F3, and for some reason, even though I'm running Acronis 2012, it doesn't seem to be able to clone the F3 over to the Hitachi. I've also tried Drive XML, and for my 2 hour wait, I only managed to acquire a boot error. Thankfully, I've not done anything rash to destroy the data on the F3, but given the fact that I've seen corrupted files in Steam from that drive, I'm not will to trust it long term with my data. I really need to get the data onto that Hitachi, though... Anyone have any advice for upgrading the HDD in a SSD/HDD system? I don't really feel like it should be so hard, especially if I've bought Acronis True Image, but maybe they haven't designed their product to handle this scenario quite yet?

While housecleaning I unplugged everything from my computer, dusted, and plugged everything back in, though I probably didn't put all the USB devices in the same order as before. Now my HDMI interface doesn't work, and the mouse and keyboard only work in safe mode. When I boot into normal mode, there's no cursor and no response to keyboard. What could have gone wrong?
