Agreed.  This is puzzling.  I'm guessing that the operating system is
not telling the Wren V to use its 32k cache buffer.  Anyone know how
to do this?

HINT: from the WREN V SCSI MODEL 94181 Product Specification:

	This feature may be selected by issuing a Mode Select Command
	with the Enable/Disable Cache bit set in the Cache Control page.

Thanks.
