I seem to remember, back in my Summer Tech days, that the DuoDisk had a
fatal flaw, usually triggered by certain copy-protection schemes, which
would cause it to destroy disks.  The fix involved opening the drive and
clipping a pair of capacitors from the internal PCB.  Does that jog
anybody's memory?  There's got to be a technote about it somewhere!
