I should hire myself out as a psychic. That's exactly the response I received from them (though slightly more polite). Do you or anyone have even a WAG as to how I can trick this thing into negotiating at u160? There was an older thread on this list where someone discovered that their drive was very unhappy about having anything faster than 12.5 ns (aka factor of '9') mentioned(?) I don't pretend to fully understand it, but since the drive in question was an SX series workstation drive of similar vintage I'm wondering if this makes sense to anyone. If so, what could I do to tailor the initial PPR request? In the meantime, I'm going to try the drive on an Adaptec 29160 in another machine and see what transpires.
