Is there anything else on the chain besides the drive? (CD Rom, for instance?)
I've had problems with the Adaptec UW controllers playing well with my CDs and
a couple of my HDs when negotiating the UW components - usually resulting
in a hang or inappropriate probing. Usually I can get around it by
cranking down the max sync transfer rate (for instance, on my CDs, I have
to take it from the default of 20 MB/s to 10 MB/s in order for it to
work). Also, sometimes its required to turn off the UW BIOS support. 

I don't know how much help this will be. I just know it works for me. :)
