    This is not true. Windows only need to understand the filesystem, in order to be able to defrag that particular partition. Drive letter or not, does not matter. That is just a human readable/accessible convenience.

    Sorry, either I worded that not quite right, or there's a misunderstanding. This is what I'm referring to. Normal home user is not likely to be running defrag commands at a command line. The UI below runs defrag.exe under the covers. Clicking on Recovery or any of the root labeled partitions simply returns immediately with no action taken.

    That is the exact command the Windows Scheduled Tasks runs. I just ran it manually in CMD. The same command will apply to all editions of Windows (Home, Pro, Enterprise, x86, x64).

    I understand all that. I'm not sure what your point is.

    Hi,

    Bottom line is MS ought to distinguish between optimizing (SSD) and defragmenting (HDD).


    Most of the stuff on the internet about what you can and can't do with SSds is really outdated.

    If I see a SSD that is really fragmented I will defragment it. It is faster after that.


    Cheers,

    Not meaning to sound like I'm dragging this out, but how do you actually defrag an SSD? Windows defrag does a trim. 3rd party I've seen won't offer to defrag, just trim. Honestly, I really don't know how to.

    Wise Disk Cleaner is what I use for that.

    I'll look into it but it might be possible to force defrag.exe to run a defrag on an SSD from the command line.

    On the servers we use Condusiv Technologies' (formerly Diskeeper) which really makes a big difference.

    According to the sources quoted in the links, Windows defrag (or Optimise drives or whatever it's called now) does not just do a trim, if you have system restore switched on.

    Thanks, guys. I'll have to look into that. I was always under the impression that a TRUE defrag was poison to an SSD.

    That is the whole point of this thread. General wisdom says don't defrag an SSD as you shorten it's life. We notice MS says it defrags, but it only happens once per month and only when System Restore is enabled.

    The question now is, does this bother you?

    My feeling is MS does it for a reason and I will get rid of my SSD long before it dies, so I don't care about extra write cycles. My oldest SSD is 7 years old and fine.
