I've seen a washing machine sized DEC disk drive, formerly used by
the Physics institute @ Bonn University's PDP-10 (don't know the 
exact type, one or two dozens of washing-machin-sized cabinets), using
128 word (36bit) blocks. When the PDP-10 was decomissioned, my
(then) boss added it to "his" VAX11/750, reformatted with 512-byte
sectors.
