This drive has a "FORCE SE MODE" jumper, but no "disable wide" jumper.
There is a "DIS F/W NEG" jumper which turns out to expand to "disable
fast/wide negotiation".  It also has three other disable jumpers:

DIS TI SY (disable TI sync negotiation)
DIS PAR (disable parity)
DIS UN A (disable unit attention)

I've tried with all four disable jumpers _and_ the FORCE SE MODE
jumper, and it _still_ doesn't work with my SS20. :-(

I am annoyed.
