When using the Get System Info(Drive Type) function, If I use either C: or C:\ for the Drive Letter it returns $DRIVE_FIXED$ as it should. However, if I use a valid mapped drive for the Drive Letter, e.g. either Z: or Z:\, the function returns $DRIVE_NO_ROOT_DIR$. It returns the same thing if I use UNC notation \\ServerName\Drive.

Is it me or is the function not working properly?

This is SetupBuilder 8.0.4063.
