This sounds like good old synchronous mode.  Edit
/sys/arch/amiga/dev/sbic.c and change 
    int sbic_inhibit_sync = 0;
to
    int sbic_inhibit_sync = 1;

and recompile.

BTW, is there really ANY reason to have sync on by default?  The worst case
with it off is that your drive may not be used to it maximum speed.. the
worst case with it on is that your drive may not work at ALL.  I know which
default .I'd. choose. :-)
