Questions About Optimising SSD

To check for Trim, run this command

fsutil behavior query DisableDeleteNotify

If the result is 0 (zero), then Trim is enabled.

------------------------------------------------------------

For alignment you check with these commands

Diskpart
List disk
Select disk n (where n is the number that was given for your SSD in List disk)
List partition

Now you should see a result like this.

Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 Primary 59 GB 1024 KB - but 64KB or any number divisible by 4 is also good

The offset (in KBs) has to be divisible by 4.

Hehe, yes, the d-word definitely lights the touch paper, my mistake.

It's great to hear I'm 555 and I don't need to do anything.

I'm fairly confident I'm still on a different page to everyone else though!

Wow your 555 years old!!! You got me beat....lol

Oh woot, now I can check.



For TRIM the result was 0, so that's great.

For alignment, in command prompt I typed Diskpart and was prompted to 'allow to make changes to computer' (which always makes me nervous). Then, List disk> return and got;

Disk### Status Size Free
--------- -------- -------- --------
Disk 0 online 476GB 3072kb

Hopefully that's where I needed to be coz when I tried inputting the next line (Select disk n) it said; The arguments specified from this command are not valid.

Anyway, 3072 divided by 4 = 768



Sounds like I'm good?

Right, you are good.

Thanks again to all. Solved.

Never say Never. See:-

The real and complete story - Does Windows defragment your SSD? - Scott Hanselman

This was found to not be the case.
window was just saying it was defragging the SSD on some pc's(for whatever reason), but was in fact only optimising/trimming them
