    Virtual drive on Hard Disk disappears after rebooting…….


    …even after doing “Attach VHD” in Disk Management (before rebooting). After rebooting, each time I have to repeat to process of “Attach VHD” to see the drive in Explorer. And also, when I see it, I can see it only under “This PC” in the Explorer and not in the folder I placed it. Any ideas why all this happens ??

    I have Windows 10 Pro 1709 on a new desktop.

    :)

    Power Outage or Reboot Resets Drive Letters

    Thank you for the reply, but I would like some clarification on the suggested solution(s).

    In running diskpart, I typed "LIST VOLUME" as suggested by Rover85. I noted that my D: drive is listed as volume 8 and my E: drive is volume 9.

    Do I then continue in diskpart with Gavin Adams answer of 1/27/2013 with the following script?

    LIST VOLUME

    SELECT VOLUME 8 (and/or 9)

    ATTRIBUTES VOLUME CLEAR HIDDEN

    EXIT

    And this will assign the appropriate drive letter on reboot?

    The one thing that bothers me is that my first try after reboot with Computer Management/Disk Management would not connect to the "Virtual Disk Service" until I did a second reboot.

    Compacting virtual hard disks


    We must have totally different working methods Virtual drive on Hard Disk disappears after rebooting……. :)

    Let's see what I told to be my workflow, and check how that works in reality. Example W10 x64 VM is one I have used for ESDtoISO and UUPtoISO testing, a clean installed build 15048 with no additional software installed, upgraded several times to builds 15055, 15058, 15060 and 15061, always restored back to clean 15048. This has of course caused the VHD size to grow to multiple times what really is needed.

    After the above, checking file sizes. Macrium image was made when the original 64 GB dynamically expanding VHD was 34.5 GB:

    Macrium image size just under 5 GB:

    After restoring Macrium image to a new dynamically expanding VHD, file size is 9.3 GB. Over two thirds smaller than original one:


    Virtual drive on Hard Disk disappears after rebooting……. [​IMG]

    The same as seen by File Explorer, yellow highlight is the original VHD, start situation, and green highlight the new VHD where Macrium image from old VHD was restored. Old VHD can now be deleted, net storage save savings over 25 GB in this example case:


    Virtual drive on Hard Disk disappears after rebooting……. [​IMG]

    (Notice that VHD has already grown over 0.5 GB since the previous screenshot a few minutes earlier. This is because in previous screenshot VM was not started yet after restoring the image.)
    This of course is all logical, happens every time.

    How to Partiton a Hard Drive in Vista

    This is a way to get Vista to see another hard drive that is not associated with the OS. There is some times when your new hdd doesn't seem to want to work well with Vista. But, there is a solution in it.

    Open the Computer Management By doing these steps.
    • Click on the Start Button
    • Click on Control Panel
    • Click Administrative Tools
    • Double click on Computer Management
    You are now in the Navigation panel of the Computer Management.
    When in Computer Management, you then have to allow the new drive to be recognized.
    • Double click on Storage
    • Double click on Disk Management
    Now in the middle of your screen there is the layout of the Disk Drives that you have. The drives that are partitioned will show by the drive lettering. The others will just show up as having nothing at all in them. Below that there will be the Disk drives that are installed into the computer. You'll see that the primary one will all ways read as "Disk 0". Then you will have Disk 1 and so on. Under the Disks there will also see your CD-Rom drives.. If there is more then one, it will be labeled the same as Disk drives..

    On to the Partitioning of the drive in question.
    • Right Click on the drive
    • Click to format the drive or Enable Volume. There will be a series of windows that open up. This is Vista's formatting. Just go threw the windows, and make sure everything is the way you want it to happen.
    • Once the formatting is done, will take some time depending on the drive size.
    • Right click on the drive
    • Click on Mark the Partition as Active
    After you have done those steps, The drive will be up and running threw Vista.



    :Side Notes:
    If you are not the Administer to the Os, then you will have to enable it..
    You may also want to redo the drive lettering of it all. But, I really don't see a reason to do so. If you do, you have to redo drive paths and so forth.. A lot of work on something so small...
