    Cannot Trim SSD's after Windows 10 Anniversary Update


    After update to Windows 10 Anniversary Update I cannot Trim SSD's.

    SSD's not recognised. I tried running "winsat formal" from an elevated (admin) command with no success.

    Any suggestions?

    Did you try thru Disk properties > Tools > Optimize ?
    Is SSD recognized as such ?
    Is Trim enabled (AHCI mode too) ?

    If you will open an elevated command prompt ( Right click the start flag and select Command Prompt (Admin) and run this command

    fsutil behavior query disabledeletenotify and press enter. It will tell you whether trim is enabled.

    DisableDeleteNotify = 1 (Windows TRIM commands are disabled)
    DisableDeleteNotify = 0 (Windows TRIM commands are enabled)

    That would tell you if Windows 10 is sending trim commands to the SSD Controller.

    Can you turn on auto optimization ? Looks like Optimize button is grayed out and optimization turned off.

    Isn't that the disk defragmenter? You should never defragment an SSD. That's why Windows automatically turns it off.

    It is and isn't, HDDs get defragged and SSDs trimmed. If you click at Optimize it trims SSD and defrags HDDs. That's how it is since w7 Sp1.
