In BIOS it appears as "P0WDC WDBNCE0010PNC"

Drive 2

    Press Win + R keys to open the Run dialog.

    Type diskmgmt.msc and press Enter. This opens the Disk Management utility.

    Look at the list of disks at the bottom of the window. You will likely see your Windows 7 disk listed, but its status will say Offline.

    Right-click on the disk's label on the left-hand side (where it says "Disk 1", "Disk 2", etc.) and select Online.

    The disk's status should now change to "Online". After a moment, it should also show a drive letter (like D: or E:) and become visible in File Explorer.

    If this works, you're done! You can now access your files.
