    Must Assign Drive Letter Each Time I Swap Drives


    I use a USB docking device and swap drives frequently. Every time I swap I must go into Disk Manager and rerereassign the same drive letter. Surely this isn't normal. How do I stop this behavior?

  2. Unable to assign drive letter to SSD partition

    Hi,

    Depending upon the number of partition and connected hardware devices Windows assigns a drive letter with which the drive is referenced. Windows uses
    MountMgr to manage drive letters. MountMgr will assign the next available drive letter to each device added, regardless of type. With the system drive assigned the letter C:, there may be other IDE, SATA or USB devices, such
    as a DVD ROM or a Flash drive assigned to letters D: and E:. When adding another drive, Windows will assign the next drive letter available, which in this case would be drive letter H:

    Drive letters can usually be manually changed using Disk Management, however there may be some exceptions. In your case, the drive letter C was already used by other drive therefore drive assigned by Windows 10 Technical Preview.

    Let us know if you have any other queries.

  3. Swapping drive letters, including boot volume

    I have a new computer. I want to clone the system to a new SSD. Can I change the drive letter of the SSD to C: after cloning?

    I have a new ASUS M52BC with:

    • 1 TB hard drive with a Windows (CMust Assign Drive Letter Each Time I Swap Drives :) and empty data (DMust Assign Drive Letter Each Time I Swap Drives :) partition
    • Windows 8.1 (I will upgrade to Windows 10 very soon) on the hard drive
    • Samsung SSD 850 EVO (physically installed but nothing more done to it)
    What I want to get to is:

    • 1 TB hard drive with the data (DMust Assign Drive Letter Each Time I Swap Drives :) partition and (for the old Windows partition) the drive letter of the C: changed to something else
    • Windows 10 on the SSD as the C:
    I don't intend to boot to Windows on the hard drive after I get Windows working on the SSD unless I need to remove the SSD for return to ASUS for repair. (My new computer had a bad motherboard when I received it but I hope I do not need to return it again.)

    I want to clone Windows to the SSD using the Samsung Data Migration tool. During the clone, the SSD will of course not have the drive letter "C". To boot from and use the SSD after the cloning, it must have the drive letter "C", correct? I assume the Data
    Migration tool cannot change the drive letter used by the software it clones.

    After the clone, how do I swap the drive letters? I assume I cannot change the drive letter of the hard drive Windows partition when it was used to boot from because it would be the boot drive, correct?

    I know that some people will suggest that I do a fresh install. I want to avoid doing that if possible.

    I see
    Migrate system partition to a new disk
    . I think that describes doing what I am trying to do, but unfortunately he does not know how he did it.
