Disk Defragmenter Schedule- Turn On or Off

You should be defragging manually, not relying on a schedule.

I have Windows disk defragmenter turned on and run on a weekly schedule. My 2 SSDs are automatically excluded and only my 2 HDDs (3 partitions) are included in the option list. The HDDs have 0% fragmentation so I just let Windows do its thing.

One annoying thing I notice is that my SSDs do not appear in the schedule list only the HDDs. The non operating system SSD has never had a defrag run. BUT my OS SSD C: does show that it is having weekly defrags even though it isn't in the "Configure Schedule" list. I don't know what's going on here

If I turn off scheduled defrag then I think I'd need to manually defrag the HDDs.

Hey Michael, :)

Technically, SSDs should only be trimmed instead of defragged.

If you haven't already, you might check to make sure that TRIM support is enabled for SSDs.

TRIM Support for SSD - Check and Enable or Disable

When I did have a combination of SSD and hard drives I did manual defrag's of the hard drives only.

I know of know SSD manufacture that want their SSD's defraged.

TRIM is enabled and I don't want Windows to defrag my SSD C: drive.
Only my HDDs are listed in the scheduled list. My C: SSD drive is not listed in the scheduled defrag list but is being defragged. I have another SSD also not in the list and is not being defragged.

I'm happy to have Windows defrag the HDDs (only) on a schedule and not have to do it manually.

So why is Windows treating C: like it was included in the scheduled defrag list?

Most likely it's automatic maintenance including the system drive.

I think you're correct here Brink.
I think a Norton Admin setting is defragging the boot drive. Under Norton Administrative settings turn "Idle time optimizer" off. It appears you need to do this even if you uncheck the obvious Task scheduling>automatic tasks>Disk optimization.

If you choose to use Norton Security and have an SSD boot drive then I suggest you turn the Idle time optimizer off.

Thank you for posing back with your findings Michael. :)
