My Question is, does Norton know I have an SSD, and is it safe to perform this on my SSD?
@MRNIGELGWILLIS YES!! Norton will detect that you have an SSD and rather than “defragging” it, Norton will trigger the Windows “Trim” command to correctly optimize it.
AI Overview
Yes, Norton’s disk optimization tools will detect an SSD and, instead of defragmenting it, they will trigger the Windows TRIM command to optimize it. TRIM is a specialized command for SSDs that is much more efficient and safer than traditional defragmentation. Norton’s optimization process generally just calls the Windows optimization function, which correctly handles the drive.
When Norton runs its disk optimization, it first identifies the type of drive.
For a traditional hard drive (HDD), it might perform defragmentation. For a solid-state drive (SSD), it will instead use the built-in Windows TRIM command.
The TRIM command works by informing the operating system about data blocks that are no longer in use, allowing the OS to wipe them clean. This is crucial for SSD performance and longevity.
You generally do not need to manually disable or change any settings, as Norton’s tools are designed to work with modern operating systems and SSDs.

Conversely, Windows will do the following on its own as a maintenance task:
AI Overview
Windows retrim is the process of a scheduled task to re-send TRIM commands to an SSD to identify and clear blocks of data that are no longer in use, which helps maintain the drive’s performance and longevity. While Windows automatically issues a TRIM command when a file is deleted, these commands can sometimes get dropped from the SSD’s internal queue. Retrimming ensures that all previously deleted data is properly cleaned up and the drive remains efficient.
How it works
When you delete a file, the operating system sends a TRIM command to the SSD, informing it that the data blocks are no longer needed.
The SSD adds this command to an internal queue for processing later.
Sometimes, the SSD’s internal queue can become full, causing some TRIM commands to be dropped.
Windows’ “retrim” process is a scheduled task that runs periodically to re-issue any TRIM commands that may have been dropped from the queue. This ensures that the drive’s blocks are properly cleared and ready for new data.
Why it’s important
By clearing out unused data, the SSD has more free blocks readily available for new writes, which keeps write speeds fast.
A retrim helps manage the SSD’s internal garbage collection process, which is crucial for wear leveling and can contribute to a longer lifespan for the drive.
For most users, the automatic optimization feature in Windows handles both defragmentation for HDDs and retrimming for SSDs, so there is usually no need to perform a manual retrim.

So basically i need to wait for the trimming and retrimming to take place using automation.
I’ll check back here in the morning thanks.
@SoulAsylum Hi there.
I have just used “fsutil behavior query DisableDeleteNotify”:
it came back with:
NTFS DisableDeleteNotify = 0 (Allows TRIM operations to be sent to the storage device)
ReFS DisableDeleteNotify = 0 (Allows TRIM operations to be sent to the storage device)
which i think means that trimming is enabled.
So i should be ok!
Thank you again. That is just what I wanted to hear.
I must confess that I did allow Norton to analyse it, and it decided then that it didn’t need optimising. What a waste of time. So long as Norton doesn’t do it without my permission. But I am glad I have seen that bit of it. The nice little map that shows the fragmentation.
Thank you again for jumping in last night
