Listing deejay
Select deejay one
Uniqueid deejay

Notation downwardly the identifier. Check if they are the same for other drives. If there is a disk with duplicate id, then you need to change the signature using Uniqueid command.

uniqueid disk [id={<dword> | <GUID>}] [noerr]

To alter the signature, call up of a unique number.
In the Diskpart prompt, type uniqueid disk ID=[NEW SIGNATURE]" with the brackets
Hit enter, and it will set a new identifier. Usually generating a GUID makes more than sense

uniqueid deejay id=baf784e7-6bbd-4cfb-aaac-e86c96e166ee

One time it is applied, the computer should automatically place the disk.
