SSD 'Cannot optimize this drive'

Or a very similar message, I'll get the exact text if required.

I was wondering why my other PC with a Crucial SSD (M128 V4) does not optimize. Defraggler states that it cannot optimize / quick optimize this drive.

To be honest its not in my main machine as its slow despite updating firmware etc, but I was wondering what / why the criteria Defraggler has used for this and why it won't optimize it. :)

What os version

What defraggler version (please don't say any form of "latest" as that provides no information, give full version number)

My apologies, after updating it to the newer version it seemed to now work.

Sounds good, glad that worked
