In regards to:

%I recently bought a PC with a 30 meg harddisk, a Miniscribe 3438. 
%The problem is that the harddisk-controller combination (a controller
%of unknown origin) is very slow, coretest reports 25 K/s. First I
%believed it was the interleave, but spinrite said it still needed
%26-32 revolutions to read one track at any interleave. There must be
%something wrong... What is the problem, and what can be done about it

Guido, I think your interleave must still be wrong.  I believe
you must do another low-level format, deliberately specify a new
interleave factor, then run SPINRITE again to obtain new results.
Remember that if your best interleave is 6:1, then anything less
(like 5:1, 4:1, etc.) will give aweful performance, while anything
higher (like 7:1) will not appear so bad.  So, if going from x:1
to x-1:1 causes performance to degrade significantly, then your
best interleave factor is x:1.
