Implement ST_Q_UNIMODAL quirk, which indicates that a drive will reject
all attempts to mode select, even if the attempted mode is supported. Add the ST_Q_UNIMODAL quirk for the HP Colorado T4000s which exhibits this behavior. (Someone please lob a tactical nuke in that direction.) From David Rosenthal <dshr@vitria.com> on netbsd-bugs.
