Latest Version tries to defrag SSD

I just upgraded to the latest patch of Norton 360. Now, it is prompting me to perform a disk optimization. I thought it meant drive D:, which is a regular hard drive, but it is trying to upgrade the C: drive, which is SSD. Shouldn't it be skipping that? I thought defragging was bad for SSDs.

Thanks in advance.

Thanks, but that disables it completely. I have been using Norton 360 for years, and it was always smart enough to know to skip the SSD but optimize my secondary drive. What changed?

Windows 10. I recently bought this computer. It wasn't trying to defrag the SSD until the latest patch.

Re: Latest Version tries to defrag SSD

Oh, OK. That KB article makes it sound like it's not really defragmenting an SSD in the traditional sense. It isn't clear from the messages that Norton 360 gives. It looks like a regular defragmentation to me.

It's still weird that it didn't try to optimize my SSD until after the patch. Thanks for your help.

 It isn't clear from the messages that Norton 360 gives. It looks like a regular defragmentation to me.

That's probably because N360 predates SSD's and they didn't update the help file.

This is what the current Norton Security on my Windows 7 machine says if you search the manual for "optimization"

During the disk optimization process, solid-state drives (SSD) are defragmented only in Windows 8 or later.

I believed that Microsoft adjusted defragging in Windows 8 and later so that it only runs the Prime function that SSD's use but this is part of what an internet article says: 

The real and complete story - Does Windows defragment your SSD?

[ ... ] 

Storage Optimizer will defrag an SSD once a month if volume snapshots are enabled. This is by design and necessary due to slow volsnap copy on write performance on fragmented SSD volumes. It’s also somewhat of a misconception that fragmentation is not a problem on SSDs. If an SSD gets too fragmented you can hit maximum file fragmentation (when the metadata can’t represent any more file fragments) which will result in errors when you try to write/extend a file. Furthermore, more file fragments means more metadata to process while reading/writing a file, which can lead to slower performance.

As far as Retrim is concerned, this command should run on the schedule specified in the dfrgui UI. Retrim is necessary because of the way TRIM is processed in the file systems
