The DLT4000 products also support the 10 byte MODE SENSE, which is required to
request the VU EEROM Parameter page because of the large amount of data that
needs to be passed back. MODE SENSE (10) can be used to retrieve the other pages as
well. Note that MODE SENSE (10) returns a different format of Descriptor data.
