I'll need to check >the bios. Given your symptoms, I think trusting the host adaptor's termination wouldn't be wise. Now, I *thought* that the 2940UW had 3 connectors: * external 68-pin * internal 68-pin * internal 50-pin You're apparently not using the external, so we can ignore that (for now). Which internal connector are you using? And why not use the connector that's appropriate for the drive? (Those converters, unless I'm confused, don't do anything for any termination.) And is the terminator a 50- or a 68-pin terminator? Consider the (wide) bus as a pair: "hi" and "lo" (referring to the 8-bt paths); you need to treat each of those paths separately.
