Can Toolbox be used to Trim in Windows 7? Using IDE. Can't use AHCI.

I can't boot into windows 7 when switching to AHCI. Did the registry change, tried to do a fresh install of Win7 in AHCI. Everything is failing when using AHCI. Works in IDE. So my question now if Windows 7 is in IDE mode, is TRIM being issued by the OS or not? The posts here say Yes and No. No definite answer.

If No, can the Toolbox software be used to manually issue the Trim command when in IDE mode? I don't mind doing this manually once a while. If Windows and the Toolbox can't use Trim in IDE, I will have to replace the motherboard. I have updated the MB's BIOS to the latest version and I can't get the darn AHCI to work with Windows. It has to be the MB/BIOS problem.

I'm going to say I don't know but as for using Toolbox to manually issue the Trim command...well you have a SSD and you can install Toolbox...so you can try it.

What Motherboard do you have?

How do I know if the Toolbox issued a TRIM.. will it give an error message if it couldn't?

If your mobo has an option to run in AHCI mode there is no reason why it should not be working. What mobo are you using? Does your mobo have more than one set of controllers on it? If it does make sure you are using the Intel SATA ports and not the SATA ports from another controller.

You can't simply 'switch to AHCI.' You have to make sure the AHCI mode is selected in BIOS before you install the operating system. To get the maximum performance it should be run in AHCI mode using the current Intel Rapid Storage Technology driver. Once this is done the SSD executes the OS TRIM commands automatically.

If you read abdu's first post, it seems he understands what Michael1966 explained, since he mentions reinstalling Windows and the registry hack to get AHCI mode to work after OS installation. I've done it both ways, and I would suggest trying what I did. First download and install the Intel RST driver. Perform the registry change. Reboot the system and set SATA mode to AHCI. Worked for me.

Your problem may be you do not have the appropriate chipset, specifically the Southbridge or ICH. I don't think all can run the RST driver. Identify your ICH, find that support page on this site for that chipset, and if it exists, download the correct RST for your OS. If you are using XP, you must load the driver during OS install, via a floppy disk.

The tool box and the RST driver will not work unless you have AHCI.

Are you sure SSD Toobox will only work in AHCI mode? It does not state that in the Toolbox User Guide.

I am not sure that is correct, can you show us where that is documented? Thanks.

TRIM will work if:

Using generic Windows 7 IDE drivers

Using MS AHCI driver on Intel ports.

Using Intel's AHCI driver on Intel ports with RST 9.6

Using Intel's RAID driver for SSD not part of a RAID on Intel ports with RST 9.6

http://www.intel.com/support/chipsets/imsm/sb/CS-031491.htm http://www.intel.com/support/chipsets/imsm/sb/CS-031491.htm

Using MS AHCI driver on other ports should work.

TRIM may not work if:

Using other IDE drivers you will need to check if supported.

Using other AHCI drivers on other ports you will need to check if supported.

Using other RAID drivers for SSD not part of a RAID on other ports you will need to check if supported.

Checking if TRIM is supported:

If you can run a toolbox for an SSD to run TRIM then TRIM is supported.

The first time I tried to install the RST driver it did not install , So I did the REG edit and changed to AHCI , Than the RST installed just fine No Problem .

@PeterUK: I agree with your statements, but given all the possible variations there might be an exception. But I do agree with you.

I could just swear I ran the Toobox in IDE mode before I had everything set up with the RST driver in a new PC. I had my first Intel SSD and was checking it out with the Toolbox prior to installing Win 7 on it. But I may be mistaken and as I wrote, I can't find anything in the requirements section of the Toolbox User Guide that states being in AHCI mode is necessary for the Optimizer to run.

As usual in PC hardware and software, there are a million details and there is always one hiding around the corner that is the exception to what we know is correct.

@Gifford: Ah yes, interesting, I did things differently than you did. I performed the Registry change first and used the Win 7 driver, msahci, first, and later installed RST. That was also three PC builds ago... so I cannot be sure what I did regarding running the Toolbox in IDE mode, I could have very well had msahci going at that point.

OK, who's up for rolling there system back to IDE mode and seeing if Toolbox runs? What's that you say... I should do it?? Well... oops, sorry, gotta go, later....

...Ok I'm back... Mr. Gifford, such language, tsk tsk. You are absolutely !@# $%& right!!!

Speaking of !@# $%&, I just read that Windows 7 SP 1 will be officially released soon, the Release Candidate is available now.

I imagine a thread on this will be started in this forum soon.

If you are interested:

You said it! I believe that article said this Win 7 SP1 only (Ha!) contains all the security updates released so far for Win 7.

I've been faithfully installing all (well... most, some of the them are useless to me) the updates that are available, and although I believe some of them are ones specifically for my hardware that I downloaded on my own, I have over 100, and I see I have five more waiting for me right now.

Given that I have installed all this stuff, what is the point of installing Win 7 SP1? Will it be smart enough to know I already have these updates? Will installing it just cause this OS to grow yet larger? Of course it likely will but is it worth it?

Open questions of course, hopefully time will tell.

What is the relationship between Win7 SP1 or hot fixes with the toolbox?

To the person inquiring about hotfixes and SP!, I think SP1 will be smart enough to do the right thing and probably, just guessing, will do one of these things:

1- Finds out you have the a hotfix already, and ignores the same from within SP1.

2- Removes your htofix and applies its own. Maybe just to be sure.

3- Reapply the hotfix on top of yours.

Either way, there should be no harm. Microsoft knows very well millions of users install the hotfixes it releases before the big service pack is released.

To answer your first question, none, got off on a tangent in this thread, so sorry.

In response to your statement about Win 7 SP1, I certainly hope so. The only harm would be unnecessarily increasing the over 20 GB size of Win 7 on my SSD.
