Windows 10: Why is my TRIM function not working after I've already checked to ensure all spaces are an...

I have a large spreadsheet that is data that was data exported as an excel spreadsheet from Autodesk Civil 3D 2024. After opening up the Excel file, I split a column of data using the Text to Columns function and used a hyphen as the custom delimiter. It worked. However, preceding spaces remained in one of the columns. I attempted to use the TRIM function. I used an empty cell in the existing adjacent column first, and then tried inserting a new column of empty cells. I first typed the TRIM function and selected the cell I wanted to TRIM, then closed the parens, but the function only turned in

Ensure Trim is Enabled?

I have read several articles on Trim and it seems like my settings are opposite of what the articles say. All articles say the setting should be "0" for Trim to be enabled.

I followed the steps to verify the status and below is what my system reports.

C:\WINDOWS\system32>fsutil behavior query DisableDeleteNotify

NTFS DisableDeleteNotify = 0 (Disabled)

ReFS DisableDeleteNotify = 0 (Disabled)

so I went through the steps to enable Trim and got this message-

C:\WINDOWS\system32>fsutil behavior set DisableDeleteNotify 0

NTFS DisableDeleteNotify = 0 (Disabled)

I then went through the steps to disable Trim and got this message-

C:\WINDOWS\system32>fsutil behavior set DisableDeleteNotify 1

NTFS DisableDeleteNotify = 1 (Enabled)

What should I actually be looking at to enable Trim??

Thanks!

 

Ensure Trim is Enabled?

Hi Thirst4Chris4, Trim is by defult turned on in Windows 10 for SSD's

Check if Trim is Enabled:

fsutil behavior query DisableDeleteNotify

Turn Trim On:

fsutil behavior set DisableDeleteNotify 0

Check if Trim is Enabled again:

fsutil behavior query DisableDeleteNotify

If that command returns DisableDeleteNotify = 0 then Trim is turned on (it is counter intuitive, 0 means trim is on and 1 means it is disabled) . . .

 

SSD Trim work at ESP(FAT32), MSR(free space) and unallocated partition or not?

Hello OveDR,

Good to see you in Microsoft Community.

SSD Trim works differently depending on the specific scenario:

1. ESP (EFI System Partition) - TRIM does not apply to the ESP because it is a FAT32 partition and TRIM is specific to file systems like NTFS that support it. However, the ESP typically contains boot files and is not heavily written to, so the impact on SSD performance is minimal.
   
2. MSR (Microsoft Reserved Partition) - TRIM does not apply to the MSR because it is an unformatted, reserved partition for Windows. It does not contain a file system or user data.
   
3. Unallocated Partition/Free Space - TRIM does not directly apply to unallocated partitions or free space because they do not contain file systems. TRIM is designed to inform the SSD about unused data blocks within a file system so that the SSD can optimize its performance and lifespan. However, when you create a new partition in the unallocated space, the SSD will be aware of the new file system and its TRIM operations will apply to that partition.
   

Regarding your specific questions:

1. When you reduce/move a partition using a Partition Manager, the unallocated partition or free space created should not contain any data that requires TRIM. TRIM is relevant to the file system within a partition, not unallocated space.
   
2. Updating Windows or deleting files from the ESP will not trigger TRIM operations. The ESP is typically small and contains essential boot files, which are not frequently modified. Therefore, garbage collection in the SSD's internal firmware will handle any necessary cleanup for the ESP.
   

As for your SSD usage:

Using 2-5GB of writes per day on your SSD can be considered normal (even less than most), especially if you have regular system activity, updates, and some application usage. Windows and system processes, as well as temporary files, logs, and other background activities, contribute to SSD writes. However, if you are concerned about excessive writes, you can check for any specific processes or applications that may be causing high disk activity using performance monitoring tools or resource monitors provided by the operating system.

If anything is unclear, please do not hesitate to let me know.
