    Sooo ... using the Samsung data migration tool, I closed the OS and data on my original 1 TB mechanical drive to a Samsung SSD for my home desktop. No glitches there.

    After that I pulled the side panel and installed the SSD in the unit, and then rebooted. The unit booted to the SSD without a problem.

    Next, I opened File Explorer and the new drive (SSD) shows up as Drive 0. However, the old drive did not appear in File Explorer, so I looked using Disk Management.

    Disk 0 (the SSD) shows up as online.

    However, the old drive shows up as Disk 1 with the following error message:

    "The disk is offline because it has a signature collision with another disk that is online."

    How do I resolve this issue?

    Thanks in advance!

    ------------

    PS (via edit): the specs in my signature are for the unit in question.

    Well ... I finagled with it and found the fix in a "right click" scenario using Disk Management. Getting the old drive online is solved, but now I have a new problem. I can't seem to format the sucker to put it all in one partition.

    This is complicated somewhat for me due to having had Covid back in February, with one of the complications being a stroke that affected my eyesight. I'm missing something in the fine print of the utility that has to be a simple click or two.

    :-(

    I'm note sure that I've followed your steps but I've had a similar problem. I've upgraded a number of computers from HDD:s to SSD:s by cloning the old to the new. The mistake I made on the first occasion was to let the computer restart with both the HDD and the SSD connected. The computer booted from the HDD and the result was that the disk signature on the SSD was changed, rendering it unbootable.

    To make it work, I had to shut down the computer when the cloning was done. Next, disconnect the HDD and connect the SSD in its place, on the same port (e.g. SATA 01). Restart the computer and it will boot from the SSD. Finally, reconnect the HDD on a different port (e.g. SATA 02) and restart the computer. It will again boot from the SSD and the HDD will get recognized. I had no problems wiping the HDD and creating and formating new partitions.

    Would it be possible to manage the HDD from the Samsung data migration tool? I mean remove the old partitions and create new ones? If so, DISCONNECT THE SSD TO AVOID MAKING MISTAKES and do what needs to be done to the HDD using the Samsung data migration tool.

    As a side note: I use TeraByte Image For Linux and have no experience with the Samsung data migration tool.

    @Christer thanks. I have felt and stumbled my way through this chore like a drunk in a package store, but I've got it worked out.

    I accidentally avoided the dilemma you described above by telling Samsung Data Migration to shut the computer down when finished cloning. My action there was because I used a USB SATA connector to do the cloning, then I removed the case to install the drive. That approach forced a shut down, otherwise I would have tripped at the same point.

    I also figured out the partitioning issue re the old mechanical drive by using a series of Command Line steps I found with Google. Essentially those steps were to open the disk partitioning utility, choose drive 1, clean the disk, re-partition it, and then reformat it to get one, large and empty volume.

    RE, your question about managing the HDD with the Samsung data migration tools: I'll have to look again at that program later today and will come back and post an answer. For now, I'll call it all resolved.

    I had a look in the manual for that program and it's cloning only. It's free but if you do tasks like this on a more regular basis, TeraByte has a number of programs that come bundled, making it pretty versatile. (No ... :eek: ... I'm not on their paylist ... :D ... !)
