+* Call to SS.VarSect in Driver:
+*
+* This code calls the driver's SS.VarSect GetStat, which will
+* update the PD.TYP byte in the path descriptor to the sector
+* size of the media to which this path references.
+* If the driver doesn't support the GetStat, it will return
+* an error, and won't touch the PD.TYP anyway, so we ignore it.
