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

There is software that will do the job

Yes, it is random:

Code:

DISKPART> help uniqueid disk

    Displays or sets the GUID partition table (GPT) identifier or master boot
    record (MBR) signature for the disk with focus.

Syntax:  UNIQUEID DISK [ID={<DWORD> | <GUID>}]  [NOERR]

    ID={<DWORD> | <GUID>}

                For MBR disks, you can specify a four-byte (DWORD) value in
                hexadecimal form for the signature.

                For GPT disks, specify a GUID for the identifier.

    NOERR       For scripting only. When an error is encountered, DiskPart
                continues to process commands as if the error did not occur.
                Without the NOERR parameter, an error causes DiskPart to exit
                with an error code.

    A disk must be selected for this operation to succeed.  This command works
    on basic and dynamic disks.

Example:

    UNIQUEID DISK
    UNIQUEID DISK ID=5f1b2c36
    UNIQUEID DISK ID=baf784e7-6bbd-4cfb-aaac-e86c96e166ee

8 hex characters-4 hex-4 hex-12 hex

Hex characters are 0-9 and letters a-f.

I'd recommend you do the diskpart command uniqueid disk. Copy the GUID. Then run uniqueid disk id={then paste the previous GUID and just change one of the four character sets in the middle}

NavyLCDR's solution is spot on. I had the same problem with an MBR disk I cloned then tried to read the original by putting it in an external usb enclosure. I used exactly that method.

Thanks everyone. I was really having an issue with the diskpart method as no one was able to tell me how to come up with a new disk signature.

I will give this a shot and return if I have any issues.

I've had this issue with my old SSD. After I clone the old to a new SSD using MiniTool Shadow Maker.

- I have changed the Disk Signature collision ID using the command prompt.
- Opened the disk management and excluded(unallocated) disk 1 that was appearing as a partition for the disk 0(new)
- Finished with a right-click over disk 1(unallocated) and selecting the option new simple volume.
- Rename the new simple volume.
