Unable to optimize SSD drive - Showing CimException for Optimize-Volume

Question

When I run drive optimization from the Tools menu of Windows Explorer, it completes almost instantly, but then it still shows Needs Optimization. If I run it from PowerShell in Verbose mode, it shows a CimException as displayed below. Please advise.

Optimize-Volume -DriveLetter F: -ReTrim -Verbose                                                
Optimize-Volume : No MSFT_Volume objects found with property 'DriveLetter' equal to ':'.  
Verify the value of the property and retry.

Answer 1

The parameter DriveLetter must be an array of CHARACTERS. You don't have a drive letter ":".

To fix your problem, remove the ":".

Syntax

Optimize-Volume [-DriveLetter] <Char[]>

Answer 2

Hi Roel Vlemmings,

It seems the Optimize-Volume cmdlet has finished resending the TRIM requests. Please manually restart the optimize drives service (defragsvc) and see if the issue persists.

Also run defrag.exe c: /retrim to see if the operation can be completed normally.

Best Regards,

Ian Xue
