Poor SSD Performance: Cannot Enable RAID For One Pair Of Drives And AHCI Separately
Oct 23, 2012
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 recently sold a pair of drives which i had installed Windows 7 onto.The drives were configured as AHCI in the bios.The buyer has come back to me witht he following message: i received the hard drives today. i can install windowsd 7 in the 2 drives. whats wrong? i try in raid mode and non raid mode and nothing.says that i can install files in this discs. what operating system was there befShort of them being damaged in transit I cannot see any reason why they would not allow Windows 7 to install on themAm I missing something? I have asked him to supply details of his motherboard. Are there any other questions I should ask?

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'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?

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.

After having rather high hopes for SSD Performance...I'm disappointed.I'm glad I got a test unit, because if I would've shelled out the cabbage for this, I'd be a little PO'd.I have an 8300 Quad Core 2.5 Intel with 4GB of RAM running Windows 7 Pro 64 Bit.Instead of trying to clone the old drive, I did what I thought was right and did a fresh install.I loaded up MSE, Office 2010 and all Windows Updates.Did a couple of tweaks (made sure defrag was off, DMA mode on instead of PIO, disabled indexing)I have all the latest chipset, mobo, video, etc., drivers.Yes, it boots into Windows to the desktop faster. No doubt.Yes, it opens up windows faster and programs SOMETIMES as well.But it multitasks terrible. If I'm download, installing, etc., anything...and try to move program to program, it's slow. To the point I think it's freezing up.I've read a few of the tweaks here...and I'm missing something I think.It's an Imation 2.5" M series 64GB drive. I know it's not the Vertex 2...but it has pretty decent specs behind it. Not the best, but it should do everything my SATA platter drive does better...period.It doesn't.What should I be looking for? (It shipped with the latest firmware, and trim is turned on...not like that matters since I only installed Win7Pro fresh a few hours ago...)

I have Windows 7 (x64) build 7264 installed and encrypted on a 32GB SSD.
(I also have a 1TB drive for storage.)
I installed it about a week ago and lately it has been becoming sluggish and unresponsive at times. Mostly when loading webpages with lots of pictures or videos. I've tried 3 different browsers with the same result. When watching streaming video, it freezes randomly for a few seconds at a time when playing (but the video play bar shows that it's loaded way past the point where it freezes). I don't think it's my internet connection, because it's pretty fast (university) and I don't have these problems in ubuntu. Also, iTunes sometimes takes 5-10 seconds to gain window focus when I click on it.
I'm having trouble pinpointing where the problem lies. It's obviously not the memory. The processor does't seem to be under a heavy load (and it has 4 cores). Could it be the SSD somehow? It is one of the cheaper ones. My ubuntu installation is on the regular hd and works fine.

I have a Microsoft Wireless Mouse 4000 that I frequently carry around. I would like to try using it to play games, but it has serious issues. Outside of a game, the mouse works perfectly fine. In game, the mouse jerks around and stutters, making it utterly impossible to use. It does not occur with any wired USB mouses.

Recently I have formatted my Usb External Harddisk with exFAT, as I heard of the benefits of it over FAT32. Its an IMATION Drive with 320gb storage. Device Properties: TOSHIBA MK3252GSX USB Device, The problem is that it takes forever to copy files from the drive as compared to when the format was FAT32. Currently, Im trying to backup all my files on my PC and I've been trying to copy out 60gb of Data that I started 10+ hours ago. The wierd thing is the progress bar moves a fraction and then stops for about 5mins before continuing the another fraction.

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 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 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 a W7 64 bit machine and I am trying to update the RAID controller driver without success.I am blocked by W7 from updating the driver and get the "Windows has determined that the best driver is already installed" message.I have tried to work around that and have been unsuccessful.Ultimately I am trying to enable a program "Hard Disk Sentinel" to view and display hard disk SMART info. Unfortunately the RAID driver controlling the HDD's on my PC have a date signature of 2009 and need to be updated to take advantage of SMART information technology

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 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 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.

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.

If you think that switching to the high performance power plan is enough to set your computer to the best plan, well, it isnt.
Heres how to set your hard drives so they are included in the high performance:
1. open control panel
2. type power in the search bar and click "change power-saving settings"
3. to the right of the plan name click "change plan settings"
4. Click "change advanced power settings"
5. Go to the hard disk section and then "turn off hard disk after"
6. Enter 0 (zero) in the box (this will change to never)
Doing this prevents your disks from being "turned off".

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 a problem with migration from AHCI to RAID on existing win 7 x64. I had AHCI HDD connected to marvell SATA 6gbit controller. I wanted to create RAID 0 on intel controller (ICH10) I created hdd image in acronis. Enabled RAID in bios and Created RAID 0 disk (2 x hdd) Restored from image to new raid hdd . When I try to boot win i get blue screen . error 0x0000007B ( so win cant recognize hdd)When I boot from win CD installer have access to raid disk what shall I do? I my opinion system doesn't have access to raid drivers. (maybe missing registry entries) i system32/drivers i have file iastor.sys but probably there is no registry entries how to add registry entries to system? How can I boot system??? ( in rescue mode windows also doesn't start)

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.

I just rebuilt my desktop and installed Windows 7. I had thought to put My Pictures and My Music on separate Hard Drives from the Operating System and everything else; OR would performance be better with all on one hard drive and backing up the My Music and My Pictures to separate Hard Drives? I'm using i7 processor with 8G RAM and 500GB hard drives (3); with a 1 Tetrabit External MyBook.

I'm trying to stripe two drives using the disk management tool. Both partitions give me the option to stripe them but when I use the wizard the other drive doesn't show up to allow me to raid to it! Both drives have partitions on them at the moment, but I was under the impression that this will make a raid partition rather than a drive.

I have two 1.5TB WD HDs that I am going to use soley for storage, these will not be for the OS drive. If I place them in a Windows 7 Software RAID 1 configuration, and say my main OS drive was to fail. I would have to rebuild my OS drive on a new HD. Now when I do this, will the new install of Windows 7 I do at the time pick up my previous Windows 7 Software RAID 1 for my storage drives or do I lose the array? I am scared that if I lost my OS drive, my R1 storage array would go as well if Windows 7 keeps some kind of settings or configuraiton to manage the array.

I've been having some issues with a computer that belongs to CEO of the company I work for. It was built by his son in law and that son in law doesn't really have time to work on it anymore so fortunately "end of sarcasm" that responsibility falls on me.Computer was running great until about two or three months ago where after shutting it down for the night and turning it back on in the morning would cause the computer to reboot three times after going through POST and during 4th time he was able to boot into OS (WIN7 64bit). I updated his bios and that seemed to fix the problem, BUT the computer was set in a Raid 1, but for some reason it is no longer set up that way. I see both HDD as separate HDD in "My Computer" C: & D:, both are 600GB with about 400GB of space free. How can I return them into their raid 1 configuration? MOBO is GA-X58A-UD7 Rev 2, Intel Core i7 970 cpu with 12GB DDR3 RAM Total. He has about $10,000 worth of programs on it (Electrical & Mechanical Engineer) and it would take me weeks if I had to start from scratch.
