As for donors, you should be able to use the 4TB or 5TB models with the SN WCJ and all 10 heads present for all patients except the WCK. For that one model, you must get another WCK.

Not yet confirmed to be 100% accurate, but if my theory holds true, you can search for "01 00 00 00 00 01 02 15" in the ROM and the sectors that precede should be the head preamp for this series of Seagate M11. Thanks Frank for getting me in the right direction with your research of its position with the SAP...saved me some time.
