    Damn it actually worked, thanks! It seems to re-trim every unused sector every time you run it, but that's fine honestly, only takes a few seconds.

    Code:
    defrag D: /L /U /V

    Invoking retrim on data (D:)...
    
    
    
    
    Performing pass 1:
            Retrim:  100% complete.
    
    
    The operation completed successfully.
    
    
    Post Defragmentation Report:
    
    
            Volume Information:
                    Volume size                 = 698.50 GB
                    Cluster size                = 4 KB
                    Used space                  = 179.57 MB
                    Free space                  = 698.33 GB
    
    
            Retrim:
                    Backed allocations          = 698
                    Allocations trimmed         = 696
                    Total space trimmed         = 695.85 GB
    Without defrag:
    Code:
    trimcheck.exe \\.\D: D:\ D:\trim.dat
    Sectors per cluster: 8
    Bytes per sector: 512
    Number of free clusters: 183063403
    Total number of clusters: 183110399
    Testing TRIM with file 'D:\trim.dat'
    ExtentCount: 1
    StartingVcn: 0
    NextVcn: 1
    Lcn: 41
    Volume file type: 1 (0)
    Old file pointer: 167936
    New file pointer: 167936
    61 62 63 64 65 66 67 68
    Press any key to continue . . .
    61 62 63 64 65 66 67 68
    With defrag:
    Code:
    trimcheck.exe \\.\D: D:\ D:\trim.dat
    Sectors per cluster: 8
    Bytes per sector: 512
    Number of free clusters: 183063403
    Total number of clusters: 183110399
    Testing TRIM with file 'D:\trim.dat'
    ExtentCount: 1
    StartingVcn: 0
    NextVcn: 1
    Lcn: 41
    Volume file type: 1 (0)
    Old file pointer: 167936
    New file pointer: 167936
    61 62 63 64 65 66 67 68
    Press any key to continue . . .
    00 00 00 00 00 00 00 00
    So it actually works. (This program just writes a new file with this pattern into exactly one cluster, opens the volume directly, seeks to the file location, reads the cluster directly from the volume, waits for you to TRIM, and then reads the cluster again.)

    Thanks a lot man! The only question that remains is why Windows doesn't realize this by default, but oh well maybe it'll get fixed eventually.

    You're welcome, you could save it as a .bat file(make sure to select "Run as admin" in advanced) and make a shortcut for it to your desktop or pin it to Start.
