Option for True Image to preserve the partition GUIDs when restoring a GPT disk
Hello,
Is anyone aware of a way to tell Acronis bootable media not to regenerate Partition GUIDs. These values appear at LBA2 offset x10, offset x48, etc) on a GPT disk.
These GUIDs are used by Windows as volume identifiers, so it is annoying for some applications that they get reset by a disk restoration.
E.g., a command like will always show the contents of the referenced partition, irrespective of the drive letter that gets assigned. But you can't hard-code it if a disk recovery is going to change the GUID on you.
`dir \\?\Volume{6c543141-114e-4059-81b7-546723afc32a}\\`.
Based on my testing, Acronis True Image will preserve the disk GUID at LBA1 offset x38 if the current value matches that of the backup (which is reasonable, since there shouldn't be an id clash by preserving the disk GUID that was already used for that disk. It seems just as reasonable that it could preserve the unique partition GUIDs, but it doesn't. They are always repopulated with random values when doing a full disk restoration.

Thanks Steve!
I take it from your answer that "there isn't a way to do it that I've somehow just missed" and "it's highly unlikely that this will be supported in the future since few users are asking for it".
I'll mark this as solved. For my purposes, if I really need to maintain GUIDs in certain cases, I suppose I can restore individual partitions and then do a subsequent hex edit of the disk to take care of data outside of the partitions that I need to be restored from my backups.
Regards,
Ryan
