Windows 7: Verifying TRIM is enabled

Verifying TRIM is enabled

I wish to confirm that TRIM is enabled on my PC (W7 Pro 64 bit). ACHI is enabled. The consistent advice I've found so far is to enter the following @ the command prompt:

'fsutil behaviour query DisableDeletNotify'.

I get the response 'behaviour' is not a valid parameter. I've tried this several times with syntax variations but every time I just get the equivalent message 'xxx' is not a valid parameter'. So I've not been able to confirm TRIM status.

Has anyone a solution to this impasse?

Cracked it! Beware differences in UK vs US spelling, 'behavior' works, 'behaviour' does not.

Welcome to the forum,

Have you tried the Yank version of behavior?

fsutil behavior query disabledeletenotify

From our tutorial,

Edit: I see you figured it out.

When I got my SSD the first time couple of months ago, I was curious of the same thing. I learned that the command only shows whether the feature is enabled or not, but doesn't check whether TRIM is performed.

Download and run trimcheck - Index of /trimcheck
It will guide you

The easy way for me to check it was to download and install SSDlife free. It will tell you in plain English if TRIM is enabled or not.

Validating or verifying an image
Hi all, I used this tutorial (http://www.sevenforums.com/tutorials/24771-system-image-extract-files-using-disk-management.html?) to create a VHD of the image of my system. It worked quite easily. However, I wanted to compare that image against the source partition. I used WINMERGE to do the...

Verifying DMI pool data, etc.
OK, so I've gone back to trying to use Windows 7 as my main OS, and as much as I hate it, I am forced to do so because certain features I need are not supported on XP. As expected, it did a good job of reminding me just why I hate it so much. Here's the thing: I am trying to preformat my hard...

Verifying DMI Pool Data
I have noticed in the past couple of weeks that, when booting up my PC, this message sticks quite a lot longer than it used to. Usually it takes only a few seconds to get past this, but now every time I boot, it can stick for as long as 10 seconds maybe. What does "Verifying DMI Pool Data" mean...
