Defrag on SSD

    Hi Jeff,

    Yep, ENYO has been defraggged. What I also see is that your ScheduledDefrag parameters are different from defaults (although RAID may be the factor here).
    Code:
    Z:\
    \\?\Volume{0b5670c0-3356-11e2-be66-c86000ddb915}\
    \\?\usbstor#disk&ven_samsung&prod_hd103si&rev_#190603306fff&0#{53f56307-b6bf-11d0-94f2-00a0c91efb8b}
    
    Defrag scheduled task parameters
    \\?\Volume{0b5670c0-3356-11e2-be66-c86000ddb915}\ -h -o -$
    Presumably, it should defrag only the HDD, but I'd like to clarify a couple of things first:
    1. Have you changed these parameters? If yes, did you do it in Disk Optimizer (dfrgui) or in task scheduler?

    2. Please post the screenshots of dfrgui with the ENYO attached:
    a) The main screen
    b) The Change settings > Choose screen

    hi Vadikan,

    i did not touch DEFRAG or DEFRAG SCHEDULER since i presumed that defrag would not happen. Before running the check i disabled the Disk Optimizer.

    So no, i did not change anyting else

    This was taken prior to the turning off.

    Here after with the choose drives, which i turned off today, a few hours ago.

    Hi Jeff,

    I see. Your ENYO is treated like a hard drive, so all you need to do is to exclude it from the scheduled maintenance along with other SSDs, and create a separate scheduled task for TRIM.

    The instructions in my blog post still stand. Of course, you have to activate "Run on schedule" first.

    Yes, Vadikan,

    but it is only the Z drive, hardly used, so i prefer to do this manual.

    In fact having SSD's not connected to the motherboard via SATA ( so USB) and your drive gets defragged.

    Nice bug in Windows8.

    Something is right until proven otherwise........

    Thanks for your effort

    A few observations from your log:
    1. The OS has been installed for just 5 days, so it's too early for the maintenance defrag to kick in.

    2. Your ScheduledDefrag parameters are different from the default (-c -h -o -$). If you want to reproduce the bug, it's better to check all volumes in dfrgui.

    3. [irrelevant to the defrag issue] Strangely, EnableSuperFetch is equal to 3 and ReadyBoot is working (*.pf files). This may change after you run system assessment (WEI). Have you done that? Unlike in Windows 7, it's been removed from the Windows 8 setup process.

    4. [irrelevant as well] 39 seconds to boot on average is pretty low for such a powerful system, unless driver/update installations were involved in reboots.

    Hopachi,
    It's a good point, and I had the same comment from my blog reader. Yet I deliberately have not included Recovery / System Reserved partitions in my instructions There's no activity on them, so there's no reason for them to become fragmented. Also, the partitions are small, so any negative impact from defrag is not worth it.

    The bottom line is I didn't want to complicate the instructions, leaving it up to advanced users to figure out But yes, I've seen System Reserved partitions defragged and more than once (e.g. here it happens every month). I have no idea why

    Vadim

    Yeah, this was shortly after setting up Windows 8.1 Enterprise Preview on my system, so there was a lot of updates and drivers the first few days.

    I'll post back with a new log after a week to see how it goes.

    My blog's got only one article in English, but it's about this issue
    Why Windows 8 defragments your SSD and how you can avoid this
    REALLY? I'll have to install Perfect Disk on those system I set up that have SSD's - I didn't know this, thanx for that info!

    Jeff,

    As an afterthought, there's nothing to do with your ENYO except excluding it from maintenance defrag (this includes disabling scheduled defrag, if you chose so). Since Windows doesn't recognize it as SSD, you can't do anything manually, i.e. you can't send TRIM.

    XweAponX,

    Really You can check and see for yourself, e.g. post CheckBootSpeed logs. As for the third party defrags, I don't really see a need for them. Certainly, if they install properly, the built-in scheduled defrag gets disabled and this would take care of the problem. But it's a pretty heavyweight approach to dealing with the issue.

    hi Vadikan,

    the Enyo does not support Trim, nor is my Revodrive X2.

    OCZ promised a fix for the Revo, but this never happened. The main reason (i think), they like to change a lot their offer of SSD's.

    Also since they bought Indilinx, they are no longer interested in SSD's with another controller. This aside of course from the topic.

    That the Enyo gets defragged, i do not care much, but it is the thought. If MS says it will not defrag SSD's, then please do not do that then.

    A few years back i defragged my Foremay Cheetah SSD's enough times to see that besides the wearing out (not good of course), SDDS's do not get any faster by doing so.

    Hi Jeff,

    Then you don't have to worry about TRIM, indeed As a side note, lack of TRIM support on the drive level doesn't mean Windows detects it as a hard drive, which is your case. Probably, the drive doesn't report itself as non-rotating medium.

    True Vadikan, my SSD's without TRIM are all dedected by MS as SSD's, only the USB connections not.

    thanks
