    Hello xbliss,

    Odd. Have you already tried to defrag using the command prompt?

    Yes. It says it cant do what I asked due to underlying hardware. It believes that I still have an SSD underneath.

    Somehow I need to make Windows 8.1 realize that I copied this partition volume to a HDD. Is there some way to remind it? Some kind of place inside a Registry key or INI or config file where I can make it REALIZE or RESET this little OLD MEMORY that its stuck to?

    I'm not sure other than a clean install.

    Found this way to make Windows reassess & check what hardware really exists. It worked on my HDD.

    I recently fitted a new SDD drive to my laptop and clean installed W8.1 onto it but there is one thing I'm not sure about. In the external link in post #1 (The real and complete story...) there is mention that 'Volume Snapshots' or 'VSC' needs to be enabled for the 'Optimise' function to run on schedule, and which as I understand it means that the standard Restore Points utility in Windows should be active and not disabled..

    Now I have System Restore turned OFF simply because I use disk imaging instead.

    So a couple of questions...

    Is having System Restore disabled the reason I have now over run the first scheduled weekly 'Optimise' ?
    Is this also the reason I don't see the 'Analyse' option, (its greyed out) and so consequently I don't see how fragmented the drive is.

    Click image for larger version

    Any recommendations (I could turn System Restore on if it would help) but you don't normally have that function enabled for other partitions and so what about those.

    Or should I just manually run 'Optimise' every once in a while. When I do this though, it all seems to be over with in seconds.

    Edit... trim is enabled when I check using a command prompt.

    Hello Mooly,

    That would only be the Volume Shadow Copy service that needs to be enabled instead. You do not need to have System Protection turned on for restore points and System Restore.

    The "Analyze" button will always be grayed out for SSDs. It's only available for HDDs.

    The optimize schedule should run as part of automatic maintenance if your computer wasn't running at the time you have scheduled.

    Thanks for the reply Shawn so I can see I have a bit of reading up to do here as I'm confusing what some of the services actually do. Looking in 'Services' and I see that Volume Shadow Copy is set to manual. Now I've never altered that (or anything in services)...... so I'm sort of wondering why its now 9 days (its just rolled past the time in my screen shot above and added another day) and nothing seems to have happened.

    "Manual" is the default setting for that service, and is fine.

    Optimization won't run if determined it's not needed though.

    What did you have your optimization schedule set to, and has the computer been running at that time?

    Ah, now that's interesting to know. It may well not need any maintenance, at least based on how I was used to defragmenting manually the previous HDD and rarely seeing more than 1% fragmentation when performed weekly. A big round of updates would push that to perhaps 3% at most.

    So perhaps that is actually a likely reason.


    The frequency is set to 'Weekly' but the PC probably wasn't on at the exact time. The standard Windows Maintenance ? routine seems to run daily in the mornings if I just leave it idling for a 3 or 4 minutes... I see the action centre flag change to show its running. I don't know if the SSD optimise would occur then if a time were missed.

    I'll leave it be and see how it goes, like many things in Windows I'm sure it knows what its doing even when its owner is left wondering (lol).

    Performance of the SSD is terrific though, things like a full image backup taking around 2.5 minutes compared to 10 minutes with old drive. So I just want to keep it like this.

I notice I have the C: in the desktop and have reserved besides the C: in the laptop. Does this mean that when I try to recover an image to the desktop containing only the C; I won't be able to? I only have one partition or drive in each.
I keep reading different interpretations on whether W8 does a trim command or defrag using the new "optimization" utility (formally defrag). Is there a DEFINITE answer on this ? Thanks
