I recently used a StarTech disk duplicator to clone a data drive, and now I am trying to view both drives simultaneously in Windows. However, when I try to access the cloned drive in Disk Management, I am getting an error message that says “Offline (The disk is offline because it has a signature collision with another disk that is online).” I am hesitant to click “Online” on the cloned drive as I am not sure what it will do and if it could cause any problems.

I did some research and found that many people have encountered this issue and suggested using the “diskpart” command in the command prompt and changing the “uniqueid” of the cloned drive. I followed these instructions and tried changing the uniqueid by adding 1 to each segment. However, even after doing this, I am still getting the same error message. I have also tried removing and reconnecting the drive and rebooting, but the error persists.

Is there any other action I should take in order to solve this issue?
