Why does this combo not sync to 160?
If I exchange the 29160LP with an 2940U2W, they sync at 80.
HDDs tested are a Hitachi U160 and a brand new Maxtor Atlas 15K U320.
I've read that for the 29160 controller 40 really should mean 4 x 40 or 8 x 40 for 160 and 320 respectively but I don't think this is right.
This is a single chain. No other drives or devices are connected and the cable is double checked and is the original with fixed terminator.
The controller setup is default but, of course, nearly any other setting has been tested with no success.
The controller has been moved to different slots with no change in performance.
Machine is IBM IntelliStation with 32 bit PCI bus. It runs very fine except for this issue.
