    \D: drive loses its letter every time after reboot.


    Need help. I used to use two different HDD in Raid 0. I removed both drives and switch to one large HDD for my storage drive. Now, every time I reboot, the D drive loses it letter and disappears. I have to open Disk Management and reassign the drive letter. This drive is my storage drive, not my boot drive. so far, I've done the following.


    1. replace my sata cables.

    2. used different power cables

    3. replaced the HDD with a SSD

    4. check for updates for my chipset and controllers

    5. check for update for my SSD


    I'm at a loss. Yes i know i can reassign the drive letter, but i shouldn't have to every time i reboot. That's called broken. Any help would be appreciated.

    :)

    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.

    Power Outage or Reboot Resets Drive Letters

    I have 2 external USB drives that were originally configured as D: and E: under W8 (F: was used by HP as the Factory Image).

    Since I have upgraded to W10, whenever I reboot or have a power outage, the drive letters are reassigned to E: and L:. This gives me multiple problems with backup configurations, program paths, etc. Also, when the system reboots, the real time clock is
    invariably wrong.

    Trying to reset the drive letters thru Disk Management requires 2-3 reboots since initially there is no connection to the "Virtual Disk Service", then the drive letter D: is not available as a choice, and finally on the 3rd restart, I am able to reset the
    drive letters. The clock never resets to real time without my adjustment.

    Any suggestions as to how I can stop this problem?

  4. \D: drive loses its letter every time after reboot.

    2nd and 3rd hard drives show two drive Letters

    Hello Andre: I followed the instructions carefully and this is what this process amounted to. I followed this step by step.

    Press Windows key + X - Worked fine

    Click Disk Management - Worked fine

    If you see your drive listed there, but no drive letter, right click it -
    All my drives showed up with there drive letters. When I clicked on the drive - Local Disk (D) (I\D: drive loses its letter every time after reboot. :). The panel came up " change drive letter and path.

    Click Change Drive Letter and Paths - for local disk (D)" and in the panel it said "Allow access to this volume by using the following drive letter and paths". In
    the panel that shows up it shows a drive icon and the letter I: . Below this are the options to ADD, CHANGE and REMOVE.


    Click Add - When I click the ADD button a new panel comes up and the only option allowed is "Mount in the following empty NTFS folder". When I enter the letter D:
    ( the drive letter I'm trying to get too) and click on the OK button it opens a new panel comes up and tells me "The device is not ready".


    Click Assign the following drive letter - I then go back a few panels and select CHANGE, this time the same panel opens up but this time the other option is locked
    in as my only choice - "Assign the following drive letter". I enter D: again and in the pull down menu the letter D is not available for me to choose.


    Click in the Drive letter list box - Then I go back to the previous panel and select REMOVE, now the new panel tells me "Some of the programs you rely on drive letters
    might not respond correctly. Are you sure you want to remove this drive letter. I did not proceed as I've done this before and it does remove the drive letter I: but the in Disk Management the now D: dive is no longer accessible.


    So now I have explored all three options that were presented when I right clicked on the "Click Change Drive Letter and Paths" In the end I was not able to remove the drive letters I and J from disk management

    Thanks very much for the assistance, do you have any other suggestions I can use to correct this issue? I thought I might try deleting the D letter leaving the drive letter I, then going back in and try changing that
    drive letter back to D done in two separate steps??? Bill
