    SSD defrag issues in Windows 8.1 RTM


    I upgraded to 8.1 and everything is fine, apart from these 2 issues: -

    1. If I start a maintenance run manually via Control Panel, Windows will start defragging my SSD, which obviously shouldn't happen. You can see it happening here, even though the drive is correctly identified as an SSD: -



    I believe this bug was an issue in Windows 8 as well.

    2. The System Reserved partition shows up in Optimise Drives, as it did in Windows 8, but I am unable to optimise it. If I select it and click the Optimise button, the Optimise Drives window disappears, reappears, but nothing has happened. It still says "Never run" and "Needs optimisation" next to it. Also, that causes an error to show up in Event Viewer each time I try it, as you can see here: -



    The error is the same each time: -

    The volume System Reserved was not optimised because an error was encountered: The parameter is incorrect (0x80070057)
    Also in that list of logged events you can see where events have been logged saying that my C drive has been defragmented and not just retrimmed.

    I have tried running chkdsk on the drive. I've tried running System File Checker. I have tried this command: -

    DISM.exe /Online /Cleanup-image /Scanhealth

    Everything checks out fine and there are no errors.

    Is this something I should be concerned about? Issue 1 only occurs if you manually start a maintenance run from Control Panel and it appears to be a bug in Windows, but that's easily solved by just letting maintenance run automatically on a schedule. It's issue 2 that I'm more concerned about. My system is running great and I don't know if not optimising that small 350 MB System Reserved partition really matters.

    Verify your SSD is running in AHCI mode. If OK, Verify TRIM is active. If you need specific guidance, see this article:

    Start By Enabling AHCI (With TRIM) - Can You Get More Space Or Speed From Your SSD?

    BTW, I have seen reports where others are having issues when trying to TRIM the System Reserved partition. That could be a real bug in 8.1 RTM.

    Thanks for the reply. Yep, it's in AHCI mode and TRIM is turned on.

    Is this likely to have any long term effects on the way my system runs? It's running great at the moment and my main C partition with Windows and software on it is unaffected by this - it's just the System Reserved partition that can't be optimised.

    You can leave the Automatic Optimization on for System reserved Partition as it's a small partition, this has been discussed in these threads, if you want to stop windows defragging, follow the instructions by Vadim in his blog.

    Right, but that is one of my issues. I cannot optimise that partition either manually or via scheduled maintenance because of the errors mentioned in my previous posts.

    Just kill "Optimize Drives" service and optimize HDD from some other program if you insist on it. Win7 (specially with SP1) and Windows 8 are really "gentle" to disks and fragment very little comparing to XP and before and do not need to much optimization anyway. That System Reserved Partition is on the SSD too so that is out as far as optimization is concerned but even on HDD has very little impact. In addition to SSD I have 2 large HDD, I push thru them a lot of GBs of files daily and barely once every few month I have to do any optimization and even then it styes under 7% fragmentation.
    SSDs have their own way of optimization in the FW and all you have to worry about is that Trim is active.

    Thanks for the help anyway. I've followed the advice in that blog post and have removed my SSD from the regular scheduled maintenance and I've created a task to retrim the C partition once per week. The System Reserved partition will just have to remain unoptimised until I can find a solution to that problem.

    I would still be concerned about the C partition not optimizing properly and I (personally) would turn off the weekly schedule until a proper optimization solution is found. Could you provide a screenshot of Disk Management? Here's mine for comparison:

    The C partition is optimising fine. It's the System Reserved partition that isn't.
