SSD how to enable TRIM command?

[Guest]

I'm using Windows 7 and hard disk sentinel says TRIM is supported on my SSD but disabled in Windows 7. I have seen on a lot of sites that I need to type this in command prompt:
fsutil behavior query disabledeletenotify
They said if it's 0 then TRIM is enabled if it's 1, it's disabled and type 0 to enable it.
However the cmd for me says 48 not 0 nor 1! So please help I have not seen anything about it on the net.

I have a kingston SSDnow v300.
I opened the cmd as administrator.

If you installed windows without AHCI as the sata mode in the bios, it will not pass trim commands.

Congratulations for not reading my whole question. -_-

Before I bought my PC I watched videos about that so I set it on AHCI but the cmd answer is that weird 48. What is that "48" response instead of 0 or 1?

as far as I can tell, no one knows for sure why that 48 value is showing up. Some people say its common with custom windows images etc.

Just set it to 0 and enable it.

Thanks this seems right since I'm using my own Windows image with pre-modified theme and things. I set it to 0 and now it says 0.

Cool. At least we can file that one away now as a very likely possible cause.
