Windows: disk offline with signature collision in disk management

How to fix an offline disk with signature collision.
If you clone a disk on Windows and leave it connected to your computer, then Windows will take the disk offline, because it has the same signature, which is basically an ID each disk has.

Offline (The disk is offline because it has a signature collision with another disk that is online)

Thanks for a clear explanation of this situation, will clicking online wipe any information on the disc? i.e Photos, saved documents in folders. Many thanks

The problem is when you attach it back the bcd will not recognize the signature 😂. Guys do not do this. If you attach a duplicate signature you would need a script to offline the disk then change the signature correlation with the bcd to boot the root again

Attachment will only result in a wtf. Let me know if YOU would like the script..i created it for an environment

[acegonzalez]

Thank you very much for your much' your advice helped out tremendously. Other YT videos show you the good but never show what to do "if" this happens. I will hit the sub button, thank you once again.

In Linux, sudo tune2fs /dev/nvme[X] -U random [or yourNewUuidNumber from uuidgen, if installed] is not as helpful as I would have hoped. Unfortunately, tune2fs is for ext2/ext3/ext4 and not for NTFS file system. Moreover, I don't know of an equivalent to tune2fs for NTFS. The command ntfslabel is not it either.

After using 'dd' to create a Windows drive replica (plus quick non-cryptographic hash verification of partitions), a signature collision emerges. Specifically, one of the drives no longer appears in BIOS even though both drives are in POST immediately after powering on! 🤕😟🙁🤔😠🤬😲🥴😢😕🥺😧🤪😎 I am stuck using Disk Management in Windows to fix the collision.

Superb video 👍 thank you.

Kindest regards, friends and neighbours.

Just had this happen for the first time in about 100 external drives ;) Didnt understand the need for all the cmd/diskpart explaining though, only made it more confusing. Would only need to know to put as online in Diskmanagement and then you are good to go :)

[jeromecenteno]

thank you, it worked. it solved my problem :)

THanks for explaining how to use diskpart, but I get the same dialog box in Computer Management when I try to select ONLINE
and get "Disk attributes may not be changed on the current system disk or BIOS disk". I have 2 ssds 512 GB and 2 TB, I cloned 512 GB to 2TB, the 512 GB has the Windows Boot so I tried to migrate to the large 2 TB. But I have problems now to do Windows Updates from 22H2 to 23H2. So I thought to revert back the 512 GB to see if I can update it and just use the 2 TB with another computer. Any help would be very much appreciated, , I wanted to put it 512 GB back online and boot into to try see I I can get those important Windows Updates.

How to make it online if the online option is grayed out for me?

[Gootek]

I have the exact same issue but from doing a system migration, when I press on "online" and go to do the system migration again, i get the exact same error.
