    Windows has stopped mounting internal and external drives


    Hello,

    Recently, I noticed that some USB flash drives were not mounted automatically. Initially I've thought it's not big deal, and just mounted them manually.

    But then, after restart, Windows decided to mount nothing but C: . I've already tried about a dozen tutorials about this, fiddling with mountvol.exe and diskpart.exe, both of which says that "Automatic mounting of new volumes is enabled".

    In the meantime, I started mounting drives manually after each reboot - yeah, not really a solution, is it. But 2 things were different:

    1. When I manually mounted some drive, normally it would just after successful mount appear in the This PC, and sometimes even automatically open the root of the just mounted drive. Now, it does not show in This PC, I must refresh This PC in the explorer at least once, to at least see a new mount appear. It no longer does automatically open in new explorer window.

    2. When I disconnect the drive, normally, even if it was a manually mounted, after disconnecting the mount would automatically disappear from This PC. Currently though, the mount does not disappear, and the only way I can make it go away (besides rebooting), so I can reuse it, is by using mountvol.exe .


    Kind of desperately, I did an repair upgrade, although to a 20H2 version of Windows. (BTW it's not as "harmless" as it might be portrayed in the tutorial, for example, it cleaned up my hosts file, and completely removed all of my custom installed certificates from secure store. And I think these are not the only two things that got "cleaned up" and I'll have to repair them)

    The only thing that has changed is, that now, Windows mount some of the external USB drives, but for example my D: drive that is internal SATA drive, gets unmounted after about two reboots, then I have to manually mount it again, and that again lasts for about two reboots.


    So, the current version I am running is 20H2.

    Hope we come up with some ideas, thanks!

    :)

  3. Internal Drive+Enclosure or External Drive

    Hi, I'm not very familiar with storage solutions so I was wondering if you guys could help me out. I'm looking to buy a 1TB+ drive for backup. External drives seem like more elegant solutions but when I looked on Newegg many reviews seem to suggest that they are not long lived (e.g. break within weeks/months). Is this true? If so, are internal drives + enclosures better? Or do any of you have better solutions that I don't know about (like I said I'm not that familiar with the storage department). Thanks.

    Windows has stopped mounting internal and external drives

    mount/unmount external drive instead of internal drive automatically

    Hi to all,
    I have lot of portable tools and data on my external drive which I use with my work and home PC. Both PCs have one built in drive with a C and D partition.
    My desktop shortcurts point to D:\myPortableProgsPath\... to call those portable programs.
    The local built in D: has just a subset (copy) of the ext. drive which I sync occasionally.

    So far I created a desktop shorcut to mount the ext.Drive like this:
    Code:
    extSSD_D.bat:
    Mount external(partion name=extSSD) as D: and internal(partion name=daten) as E: . If external not present mount internal as D:
    Code:
    Now I thought about a 2nd shorcut (and .bat) to safely eject the external and call the above .bat to remount the internal D again.

    1 That would OK, if there is a way to call the Win10 built in eject from a .bat (I am to old to learn PowerShell ;-). I read those.

    1a And I tried mountvol /D, but this unmounts the drive not matter a file is opened ! It just removes the drive letter and does not unmount the device.
    mountvol /P like diskpart REMOVE ALL DISMOUNT unmounts the device BUT if one reconnects the drive you have to manually assign a letter again :-(...

    1b this works:
    Code:
    but what if the drive letter is not assigned ...

    This would be great if there is a methode that works on the volume or volume label - any idea ??


    2 What would be great too:
    Whenever my external drive is connected, I want it to substitute D: and when diconnected the second partition of the builtin drive should be D: again. The thing is that there are several kinds od disconnect that could happen... e.g. eject via taskbar (tray) safe eject, during power off or accidentenly,... so maybe soltion 1 is the more secure way to go.

    - - - Updated - - -

    no ideas ;-) ?
