This is a well documented problem with the new cable that ICD is including 
with their host adaptors (DMA cable, from HD to computer).  You need to 
call ICD and ask for a new cable, which they will send for free.  This seems
to happen only to some machines (or so ICD told me).  It is a shame, since 
this cable looks much nicer than the older ones (one of which they will send
you to fix the problem).  Ah well, it's behind the machine anyway . . .
