| Post subject: | 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 |

You can examine sector 0 with a disc editor such as DMDE: https://dmde.com/ |
