Get the symbolic link of physical drive.

NTDEV
1

Hi all,
I’m developping a user mode service. I will use the service program to
monitor the add and remove of the physical drive.
I implement it in this way:
1.RegisterDeviceNotification with filter DBT_DEVTYP_DEVICEINTERFACE
2.Process the WM_DEVICECHANGE message
What I need is to get the symbolic link of the physical drive like
“\.\PhysicalDrive1”.
I can do it by send IOCTL_STORAGE_GET_DEVICE_NUMBER when physical drive is
arrival, but it seems I can’t do this when it is removed.
So could anyone offer some idea? Thanks in advance.

So what? you’re getting the device interface name. When it is arrived, get the device number, and save it to DevInterfacePath -> PhysicalDriveNumberPath map.
