  1. Cloning and disk signature collisions


    I do both a clone of my C drive and an image backup.

    On a couple of occasions I have had to boot the newly cloned drive and forgot to remove the original source drive.

    This gives me Disk Signature collision which I think I understand.

    What I'd like to do is change the disk signature of the original source drive which is a GPT SSD.

    All the articles I've found on the net seem to suggest using diakpart which I have no problems using. Where I do have an issue is with determining how to provide a new disk signature.

    What is the format of the GUID GPT disk signature?

    How do I create a new disk signature? Is it just a string of random numbers?

    If diskpart doesn't like the format or the actual id how do I create one that diskpart will accept.

    Thanks

    :)

  2. CLONING CAUSES SIGNATURE PROBLEM

    Hi Jim,

    This issue might be a cause of attaching a cloned disk to a Windows system that has a disk with the same signature.

    We will wait for your response.

    Disk Signature Collision Problem


    Disk signature is applied to the whole disk, not partition. Normally happens when you clone the disk and is available in Windows 10. Here's an example:
    I change the last digit from 6 to 7 then change back from 7 to 6:
