![]() ![]() It also includes a variety of powerful features that let you customize your alignment results. It lets you quickly and easily align DNA, RNA, and protein sequences. This answer gives a good overview of the various types of ids/UUIDs involved.DNADynamo is a powerful biological sequence alignment editor and sequence analysis software. If 2 disks have the same disk identifier, it can confuse the BIOS/UEFI boot process because it might not know which disk is which. The two partitions on each drive also respectively have identical partition UUIDs. In this example, sda and sdb have the same disk identifier (i.e. This displays something like this: NAME SIZE TYPE PTUUID PARTUUID Use this command: lsblk -o NAME,SIZE,TYPE,PTUUID,PARTUUID This sends predefined input to the fdisk command to do these steps: If your old disk is /dev/sdb, you can run this command to give it a new UUID disk identifier: printf '%s\n' p x i $(uuidgen) r w | sudo fdisk /dev/sdb ![]() If your disk is not an SSD: sudo cat /dev/zero > /dev/sdb (if you want to erase it securely, use the -s option if it's supported. If your disk is an SSD: sudo blkdiscard -f /dev/sdb The examples below assume that your old disk is /dev/sdb If you don't need any of the previous contents of the source drive that you just cloned, the easiest option is probably to discard its contents entirely. Solution 1 - Totally erase your source drive It turns out that the Clonezilla boot disk has all the necessary tools to fix the problem. I just faced this when I cloned a small SSD to a faster and larger NVMe drive. I did try and do some research on this, and had a look at an article ( ) regarding this issue, but it's not clear in the article (where it talks about restoring the Disk Signature) whether they're talking about somehow magically restoring original Disk Signature of the destination drive to what it was before it got replaced in the cloning process, or if they're talking about generating a new Disk Signature with Windows (by bringing it online) and then using BCDEdit to update the Windows BCD on the old disk. Is the SSD okay considering it's had its disk signature replaced with that of the old disk? Research suggests that it should be fine, and indeed that the destination ssd's drive signature would need to have been changed in order for me to boot from the cloned Windows installation, but because I lack knowledge in this area, I am uncertain whether or not this assumption is correct.Īlso, just in case I want to boot from the old disk, but still see the SSD in Windows (and vice versa), what would be the best way to go about updating the disk signature of either the old hard drive or the new SSD (so that I can boot from either drive and also be able to see both drives no matter which one I choose to boot from)? I've done some reading into this, and it looks like this disk signature is something that is stored in the "Master Boot Record" of the disk, and is also referenced by Windows in its "Boot Configuration Database", and the exact copy of the disk done by Clonezilla has also duplicated the disk signature. Computer Management's Storage section displays the following tooltip for the offline disk: Offline (The disk is offline because it has a signature collision with another disk that is online) I can boot into Windows 10 from the SSD without any apparent issues, however the other disk (the original source drive) is offline. Both drives were of identical size, and the process appears to have worked successfully. I have cloned a hard drive to an SSD using Clonezilla. ![]()
