RD51 reduced write current signal?

[Paul Koning]

Looking at the DEC Pro documentation there's some ambiguity I'm trying to figure out.

The hard drive documentation talks about the "reduced write current" signal.  In one place it's explicitly described as relevant to the RD50 only.  But later on in the RD50/RD51 chapter the signal is described generally, without any indication that RD51 ignores it.

Does anyone know which is correct?  If RD51 also uses it, how does the right value get set?  What IS the right value, anyway?
