    Internal drive # changes for no apparent reason.


    Drive C: the PC's Boot SOURCE was always Drive #0, now its Drive #2.

    How can this happen?

    It can happen.

    Disk drive numbers may not correspond to the SATA channel numbers when you install Windows on a computer that has multiple SATA or RAID disks - Microsoft Support


    The disk numbers that are assigned by Windows after it switches to native Windows storage controller drivers during startup are dependent solely on the order in which the disks are enumerated and processed by Plug and Play. ... Various uncontrollable timing factors may affect the enumeration order.

    Devices are presented in the order in which they are enumerated. Therefore, the disk assignment numbers may change between startups.
