    So one of my SSDs was throwing up this error when looking at its status in the Disk management tool.

    I followed the instructions here (below) to try and fix it, but now whenever I plug the drive in via USB (regardless of computer; I tried it on my laptop as well) it BSODs the computer and I have to disconnect the SSD before the computer will reboot.

    I just want to get my data of the primary partition, which should still be fine. I am pretty sure just the master table has been hosed.

    What are my options to do this? Some sort of safe boot/repair disk? Linux emergency distro?

    The drive was formatted as GPT if that makes any difference.

    Disk cloning and signature collision.

    I cloned my HDD to a samsung SSD using samsung magician.
    I then interchanged the SATA connectors of the two disks.
    System booted from the SSD with no problems.
    The HDD was not shown in file explorer and checking with Disk Manager I saw that it was offline because of signature collision.
    Using diskpart I changed the HDD ID. The picture below shows the IDs. Disk 0 is the SSD and Disk 1 the HDD.
    But still geting a collision. I still haven't right ckicked the offline icon in disk management to online *Smile.
    What am I missing here? Disks with different IDs shouldn't collide.

    Disk offline because it has signature collision with another disk online

    Hi everyone.

    I recently clone my Operating System WIndows 10 from my Hard drive to Samsung 970 Evo Plus m.2 NVME using Samsung Migration, however in disk management the new SSD is offline with the following notification "Disk offline because it has signature collision
    with another disk online".

    I really want to boot up the SSD to my laptop to have faster start up.

    How can I resolve this problem? Thanks in advance.

    Disk offline because it has signature collision with another disk online

    If you right click the space that shows Offline and select Online, windows will automatically change the disk ID and you can use the drive.
