Offline activation easeus disk copy6/11/2023 ![]() ![]() The licensor of any software or other intellectual property installed on that disk has no idea what your intentions are with respect to that copy. ![]() ![]() Simply consider that when you clone a disk (or create or restore an image of a disk), you are making a copy of the contents of that disk, including the software on that disk. (I suspect such an activation process would be a nightmare for enterprises.) None the less, a disk cloning/imaging utility that sets out to defeat the functionality of a product license activation process would be an entirely different kind of utility. I am not aware of any product license activation processes that tie the activation process to disk signatures or partition signatures. Casper clones the volume serial number by default, but this can be changed in the Casper Options (e.g., Casper Explorer -> Options -> Copy Preferences -> Always copy volume serial number). A volume serial number is assigned when a drive is formatted. While some product license activation processes are known to tie the license activation process to a drive's volume serial number, this is yet another number. Again, Windows uses these values to maintain the association of volume names on a GPT partitioned disk. A GPT partitioned disk also uses unique partition signatures - i.e., on a GPT partitioned disk, the disk as well as all partitions are assigned different GUID values at time of creation. This signature is what Windows uses to associate volume names (e.g., drive letters, unique volume names paths, etc.).Ī disk signature for a GPT partitioned disk is a globally unique id (GUID) generated at the time that the disk was initialized. For example, if more than one disk attached to your PC has the same disk signature, Windows will take the conflicting disk(s) offline.Ī disk signature for an MBR partitioned disk is a pseudo-random generated 32-bit value based on the time that the disk was initialized. There is no way around this because Windows uses this signature to differentiate disks and identify volumes. Here's their response.Īll disks must have an unique disk signature assigned. I was curious about it so I contacted Casper's tech support with your query. I've been using the Casper disk-cloning program () for many years, chiefly as a comprehensive backup vehicle and I never have run into the issue you raised.
