I just bought one of these drives, I'll check it tonight to see what it shipped default with.
Because, according to:
http://www.storage.ibm.com/techsup/hddtech/djna/djnajum.htm
"16 head logical architecture is enabled as the shipping default. Master is set to on (i.e. jumper on pins A-B and G-H). No other jumpers are fitted."
