	When the A3000 was designed, the clock rate to the WD chip was
doubled, but current released versions of the kickstart (scsi.device) don't
have changed timeout values, which depend on clock frequency.  The next
release should have proper values (note that the only other unit I've ever
seen a timeout with was a Seagate ST125N).  Registered developers already
have betas with the modification.  If you obtain the BattMem program (on
comp.sources.amiga.*) you can set the "seagate" bit, which increases select
timeouts to ~1 second, among other things.  That should hide your timeout
problem for the time being.
