It's likely the 32M media is a different chipset than the 8M.  Please see
this page:  http://www.root.org/~nate/freebsd/quirks.html
Then read the quirks sections of the listed files to get an idea of how
the quirks are used.

I'd try a scsi_da.c quirk of DA_Q_NO_6_BYTE first.  You can just use
"Generic", "*", "*" to start with.
