About this tag
The drive number tag covers discussions about Windows reassigning physical disk identifiers such as Disk0 and Disk1, often after a Windows 11 update or clean installation. Users report that the operating system may swap drive numbers, causing confusion about which disk is the primary boot drive. This can affect system configuration, boot order, and disk management tasks.

It is relevant for users managing multiple drives in a Windows environment who encounter unexpected changes to disk enumeration.
