+It is recommended to set up the st driver to return logical tape 
+positions rather than physical before calling dump/restore with 
+parameter Q.  Since not all tape devices support physical tape 
+positions those tape devices return an error during dump/restore when
+the st driver is set to the default physical setting.
+Please see the st man page, option MTSETDRVBUFFER, or the mt man
+page, on how to set the driver to return logical tape positions.

+Before calling restore with parameter Q, always make sure the st
+driver is set to return the same type of tape position used during the 
+call to dump. Otherwise restore may be confused.
