TRIM for SSD drive

Anonymous
2019-12-03T16:38:20+00:00

I have a new Dell desktop PC with WIN 10. It has a hard drive (D:) and a SSD (C:). In the past I have always defragged my hard drive but I understand that I should not optimize/defrag the SSD - that WIN 10 by default uses TRIM to optimize the SSD. I read that TRIM is set as a default in WIN 10 and that it optimizes the SSD once a week. But when I look at the properties for the SSD drive, it shows that it has not been optimized for 14 days.

  1. How do I know that TRIM is working?
  2. If it isn't set as a default, how to I change that?

Thanks.

    Hi Marian

    Trim does not run once a week, it runs automatically when required and that will not be reflected in that optimize application, take no notice of the report for your SSD in that application . . .

    Click your Start Button, then just type cmd and hit Enter, Command Prompt will open . . .

    Paste this into Command Prompt and hit Enter:

    fsutil behavior query DisableDeleteNotify

    If that command returns a 0 then Trim is activated and working correctly . . ..

    Hi Marian

    Trust me, once that returned 0, then everything is as it should be . . .

    That setting is counter intuitive, in the registry and many other parts of Windows, 1 is true (enabled) and 0 is false (disabled)

    So, because that setting is Disable . . . that means 2 negatives make a positive, so that can be read as DeleteNotify is enabled - all very confusing . . . basically Disable + 0 = 1, which is enable . . .

    Thanks so much Dave for your reply. After I used command prompt, it gave me the following:

    NTFS DisableDeleteNotify = 0 (Disabled)

    ReFS DisableDeleteNotify = 0 (Disabled)

    So it returned a 0 indicating that TRIM is activated as you said, but why would it then say "Disabled"?

    Thanks again for your expertise.
