Ok, this is "aborted command". This probably means that this mode (16)
is not supported. This drive claims to support 128 sectors multimode-transfer,
and the spec says lower values MAY be supported.
While we're on the subject, This part of the code is a bit obscure to me
(in wdattach():)
        } else if (d_link->sc_params.wdp_maxmulti > 1) {
			d_link->sc_mode = WDM_PIOMULTI;
			d_link->sc_multiple = min(d_link->sc_params.wdp_maxmulti, 16);
		} else ...

Why limit the number of multimode transfer to 16 sectors ? If the drive claims
to support wdp_maxmulti > 16, 16 may not be supported. The max value
of wdp_maxmulti is 128 sectors, which does 64k transferts.

Ok. I'll also need someone to test the new driver on ATARI :) I hope
to have something working at the end of this week.
