How to fix Disk Signature Collision problem in Windows 11/10

Storage devices are an important part of the computer arrangement for saving, porting, and extracting data files. In club to differentiate between storage devices on your calculator system, each storage device is tagged with a unique number called Deejay Signature for identification. The unique deejay identifier is stored every bit part of the Primary Boot Record (MBR). Operating systems use disk signatures to place and distinguish the different data storage devices, and hard disk drives in the computing system for data access.

What is Disk Signature Collision

Nowadays, Disk cloning has go quite a common practice for upgrading to a larger difficult disk drive. Drives are cloned to make a similar re-create to apply both the cloned re-create and original drive together. Besides, many virtualization tools are being used to virtualize the physical hard disk drive. The physical difficult drives are virtualized to create virtual hd drives, and several virtual machine clones are created with the existing Virtual difficult deejay drives. As these are identical copies, the chances are that these copies may have identical deejay signatures. When you utilize both disks having identical signatures at the same fourth dimension, you may see the Deejay Signature Collision trouble.

The occurrence of disk collision is rare every bit the Windows system doesn't allow ii disks to function at the same fourth dimension when they have a like disk signature. In the older Windows versions like XP and Windows Vista, the signature collision would often go unnoticed as the Windows system would automatically replace the signature of the disk that reports duplicate signatures.

How to fix Deejay Signature Collision on Windows xi/10

Notwithstanding, in the case of Windows 7, Windows 8.1, Windows 10 and Windows eleven, Disk Signature Standoff is handled differently. When two storage devices take an identical deejay signature, the secondary drive that creates disk signature standoff will be turned offline, and cannot be mounted for use till the collision is fixed.

You may see the following disk collision error messages in Windows 11/ten.

• The boot choice failed considering a required device is inaccessible
• The disk is offline because it has a signature standoff
• This deejay is offline because it has a signature collision with another deejay that is online.

To fix the deejay collision trouble, y'all can brand use of the command-line utility chosen diskpart in Windows PowerShell or Control Prompt to view and alter the signature, or tin can make utilise of the Master Kicking Record in the Windows Registry. You lot can as well make use of Windows Disk Direction Utility to modify the signature.

We next explain how to ready the Deejay Signature Standoff trouble.

Right-click on the disk that is marked as Offline or Missing.

Select Online control from the drib-downwardly carte.

Change Disk signature using Diskpart

Open Control Prompt and Run as Administrator. Blazon the command Diskpart to open up Diskpart and hit Enter.

Type the following command to display all the available disks on the system:

listing disk

Now note the problematic disk number with the status Offline from the list and write the following control – where 10 is the offline disk – to select the offline disk:

Select deejay x

For example, if y'all type the command select disk 1, the command prompt will display the message as Disk i is now the selected disk.

Type this command to brandish the disk's signature:

Uniqueid disk

To alter the disk's signature and set the disk online, type the command unique disk ID= (New signature) where (New signature) is the new ID in hexadecimal.

For example, you tin can set the new id as uniqueid disk ID= 1456ACBD.

If y'all have given the wrong format ID, the prompt volition display the mistake:

The specified identifier is non in the correct format. Blazon the identifier in the correct format: in hexadecimal grade for an MBR disk or as a GUID for a GPT disk.

In one case done, the deejay volition exist online. Reboot the system.

Like issue: The disk is offline because of policy ready by an ambassador.

That's all.
