    Can I change drive "numbers" for a more useful display?


    I am a big fan of MiniTool Partition Wizard but I don't like the way that the drives are listed 1, 2, 3, etc, because they don't match up with my drive letters, starting with C: Can I change this?

    To help us understand better visually, please post a screenshot of your Disk Management. Make sure that ALL the text in ALL the columns is visible and showing the whole window. UPLOAD the screenshot using one of the following methods . . .

    Alternatively, if you have > MiniTool Partition Wizard Free or > AOMEI Partition Assistant Standard, use one of those instead.

    I hope this helps.

    In most cases it takes the numbers from the controller its on so ideally have c on disk controller 0 d on controller 1 etc

    I'm using MiniTool, which I prefer to Disk Management. Between NVMe, SSD and HDD I have too many drives to fit into the screenshot all at once. This gives you a good idea.

    These disk numbers are controlled by the computer and can't be changed by the user.

    It complicates things when you have different typed of controllers. For example:

    If you have both PATA (IDE) and SATA controllers on the motherboard the numbering starts with Disk0 for PATA disks. For example, if you have 1 PATA HDD and 1 SATA HDD and you boot from SATA drive the numbering will be as follows:
    Disk0 - PATA HDD D: data drive
    Disk1 - SATA HDD C: boot drive

    If you have both SATA HDD and NVME SSD controllers on the motherboard the numbering starts with Disk0 for SATA HDDs. For example, if you have 2 SATA HDDs and 1 NVME SSD and you boot from SSD1 the numbering will be as follows:
    Disk0 - SATA HDD1 D: data drive
    Disk1 - SATA HDD2 E: data drive
    Disk2 - NVME SSD1 C: boot drive

    However, if you have no SATA HDDs and 2 NVME SSDs and you boot from SSD1 the numbering will be as follows:
    Disk0 - NVME SSD1 C: boot drive
    Disk1 - NVME SSD2 D: data drive

    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. Windows will enumerate available fixed disks, followed by removable disks, assuming that the correct native Windows drivers are already present and installed on the system. Various uncontrollable timing factors may affect the enumeration order.
    I haven't seen any documentation about how nvme disks are enumerated..

    Bummeroonie.

    Maybe that's a future BIOS option.

    ChatGPT says this - backup first and no guarantees for information from a Artificial Idiot since the reply might be a work of fiction.

    If you want to change the disk number assigned to a particular disk, you would need to use a workaround by manipulating the disk signatures in the Windows Registry. Here's a step-by-step guide on how to do it:

    Important Note: Modifying the Windows Registry can be risky, and incorrect changes can cause system instability or data loss. Make sure to create a backup of your important data and create a system restore point before proceeding.

    Press the Windows key + R on your keyboard to open the Run dialog box.

    Type "regedit" (without quotes) and press Enter to open the Registry Editor.

    In the Registry Editor, navigate to the following path:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\SCSI

    Under the "SCSI" key, you'll find numbered subkeys (e.g., "Disk&Ven_XXXX&Prod_XXXX"). Expand each subkey until you find the disk you want to change the number for.

    Look for the "Device Parameters" subkey under the disk's subkey. Right-click on it and select "New" -> "DWORD (32-bit) Value."

    Name the new DWORD value as "DiskNumber" (without quotes).

    Double-click on the "DiskNumber" value and set its value data to the desired disk number you want to assign. Make sure to choose a number that is not already assigned to another disk.

    Close the Registry Editor.

    Restart your computer for the changes to take effect.

    After restarting your computer, the disk should be assigned the new number you specified. Please keep in mind that modifying disk numbers in this manner is not officially supported by Microsoft, and it is recommended to exercise caution when making changes to the Registry.

    There is nothing to fix. It is just the way computers have been designed.

    I just didn't make up the examples I gave. These are just observations I have made with the computers I currently have.

    Computer #1
    Motherboard: ASUS A7N8X-E Deluxe
    PATA ports: 4 IDE drives (2 ports) (3.5" HDD or ODD)
    SATA ports: 2 SATA drives (3.5" HDD)

    Computer #2
    Motherboard: ASUS Prime X370-Pro
    SATA ports: 8 SATA drives (2.5"/3.5" HDD or 2.5" SSD)
    M.2 port: 1 M.2 drive (either SATA SSD or NVME SSD)

    NVME does not work directly from SATA ports (drive 0, 1, 2, 3 ) where the numbers are hardwired.

    So the drive number is a "logical" number rather than hardwired. So NVME C drive gets logically assigned the next drive number after hard wired SATA ports get assigned the next logical drive number after any "hardwired" SATA ports.

    This is normal behavious and is the same on all pcs not just ASUS.

    In any case, this is not a bios issue as drive letters are assigned to ports as part of windows booting setup.
