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?

It sounds like you have taken the correct steps to resolve the “signature collision” error by using the “diskpart” command to change the uniqueid of the cloned drive. However, since the error persists, there may be additional steps you need to take.
One possible solution is to use the “diskpart” command to clean the disk and create a new partition. This will remove any existing partitions and data on the cloned drive. Once the drive is cleaned, you can create a new partition and format the drive. This should give the cloned drive a new signature and resolve the collision error.
Another solution is to assign a new drive letter to the cloned drive using the Disk Management tool. This can be done by right-clicking on the drive and selecting “Change Drive Letter and Paths.” Assign a new drive letter to the cloned drive and then you will be able to access it.
It’s worth noting that using either of these solutions will erase all data on the cloned drive, so make sure to backup any important data on the cloned drive before proceeding.
You should also consider consulting the manual or technical support for the StarTech disk duplicator you used for the cloning process, as the issue may be related to the specific hardware or software you used.
