Thank you very much for the info.

This problem has been occured since drive #8 is moved from #1 and
added #1.  I know there is jumper for terminator on DCAS-34330W, and I 
am sure I removed jumpers for that.  So I expected to hear that there
were a special tip for using narrow and wide drives together with
AHA-2940UW.

I think I set terminator configuration on AHA-2940UW to "automatic".
According to your idea, AHA-2940UW may misrecognize devices and might
set terminator "on" instead of correct status "off", if all the drives 
have been set correct.  So, I may have to turn off the terminator on
AHA-2940UW manually.

Does anybody know tips of more than 8 drives in such a sutiation as
this?  Thanks in advance.
