Yes, that's the window.  It's something like "show drive configuration"
or something like that.  It shows "NO" for all of the possible parameters
(except ANSI compliance).  I would have expected that it says "yes" for
"SYNC TRANSFERS" ... So I guess that this point I don't know how to 
determine whether the maxtor and adaptec card have negotiated sync
communications.  Is this something that gets "set" and always works
that way from then on, or does the negotiation occur on every transfer?

Thanks for your response.

Bill
