I upgraded my SSD by dd'ing the old drive to a new drive under Linux. This has the side effect of also copying "empty space."

Is there a way to ask Windows to trim the NTFS unused blocks? Other than filling up the drive with a giant file and removing it? On Linux we would use fstrim.

Closest existing question I could find was this one that points to vendor tools that trims the whole drive, or a tool that simply fills the drives and removes the file:

You can use the Optimize-Volume cmdlet in an elevated powershell:

PS C:\>Optimize-Volume -DriveLetter H -ReTrim -Verbose
