Windows 8 is defragmenting SSD disks whenever it starts the disk optimizer via Automatic Maintenance.

It has been well over a year now since this was first reported in this (now "archived") thread:

Here's a screenshot of "Optimise Drives" opened while Automatic Maintenance was in progress.

This is incorrect behaviour and will be causing unnecessary wear on the untold millions of SSDs in Windows 8 systems.

the picture wouldn't open up for me but I have an Intel and a Samsung SSD in my Windows 8 box and neither of them "defrag"...they run the trim cycle during automatic maintenance.  How can you tell it is defragmenting?  Does it tell you how "fragmented" the drive is like it would for mechanical HDD?

****Edit- Ok, I can see the picture now.  It sounds like an issue with either drivers or your SSD.  Time to talk to your manufacturer for drivers as its not properly reporting the the OS if its a HDD or a SSD.

Which AHCI driver do you use? The MS driver or Intel/AMD? Try the opposite one and see what happens.

I'm using the Intel driver and my SSD is not defragmented during Automatic Maintenance.
