Windows 10: I cloned system OS to external SSD in m.2 tray - no signature collision

I cloned using diskgenius my system OS using winPE to an external SSD in a M.2 USB tray.But when I inserted the new drive in the usb slot, it just booted up with letter D: system is C: and looks like identical clone. However I did not get a signature collision and the drive was not offline.Does it mean the clone was not identical? Or windows automatically changed the signature of the cloned OS drive?I can confirm that the new cloned SSD has a different identifier. Is it default behaviour to set a new ID for cloned drive in win 11?Will it still boot?

Disk cloning and signature collision.

I cloned my HDD to a samsung SSD using samsung magician.
I then interchanged the SATA connectors of the two disks.
System booted from the SSD with no problems.
The HDD was not shown in file explorer and checking with Disk Manager I saw that it was offline because of signature collision.
Using diskpart I changed the HDD ID. The picture below shows the IDs. Disk 0 is the SSD and Disk 1 the HDD.
But still geting a collision. I still haven't right ckicked the offline icon in disk management to online *Smile.
What am I missing here? Disks with different IDs shouldn't collide.

 

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
