SSD TRIM turns off after Windows 7 x64 reboot

[MetaCortex]

Recently I've learned bout the TRIM for SSD drives

The problem is that after executing the
fsutil behavior set DisableDeleteNotify 0
command in CMD [even ran as an Administrator], after a reboot it goes back to being turned off

And this happens for both my SSD drives:
- 2.5" ADATA XPG SX900 128GB
- 2.5" 850 EVO 500GB

I'm operating on up-to-date Windows 7 x64. I have activated also AHCI in my BIOS

Make sure AHCI drivers are installed.

In Device Manager I have Standard AHCI 1.0 Serial ATA Controller listed under the IDE ATA/ATAPI controllers

Does this constitutes as installed AHCI drivers?


And I now the the AHCI is working, because before I switched to it in BIOS, by benchmark tests showed my SSD drives with speeds as if there were HHDs

And here is what I've discovered recently



My old method of checking if TRIM is activated still tells me it needs to be activated. It is a piece of software called TRIM Check [by Vladimir Panteleev]

But HD Trune Pro 5.60 Trial show me than TRIM is enabled

So how can I check if TRIM is turned on or off?



And is this a manifestation of problems coming out of the fact that my Windows 7 wasn't installed on a SSD already working in AHCI mode?

You can open the Admin Command prompt and type:
fsutil behavior query DisableDeleteNotify
Possible results:
DisableDeleteNotify = 0 : TRIM is already enabled and working in Windows
DisableDeleteNotify = 1 : TRIM is not enabled

 

[MetaCortex]

I have
DisableDeleteNotify = 0
and confirmation in HD Tune

So I guess it's just that TRIM Check [by Vladimir Panteleev] that is no good



So I think that covers this topic. Thank you for the info
