Try using CrystalDiskInfo (free) or HWiFO64 (free). Both of those show the serial number of the Dell OEM (Micron) NVME SSD in my Dell desktop PC.
Until the Latitude 5430 we were able to use the Wmic (or the Get-WMIObject using powershel)  command to obtain obtaining the disk model and serial number. Wmic diskdrive get caption, SerialNumber, FirmwareRevision  Powershel: Get-WMIObject -Class Win32_physicalmedia -ComputerName $laptopname | Format-List PSComputername, SerialNumber However with the Latitude 5430 I am getting SerialNumber : FFFF_FFFF_FFFF_FFFF. it might be a coincidence, but it looks very unlikely that the serial number of this drive = FFFF_FFFF_FFFF_FFFF. Short of physically inspecting the drive, is there another way to obtain the serial number?
