Harddisk on M24/AT&T 6300

[Frank W. ten Wolde]

I would like to know your (NetLanders) opinion about the following:

I have a AT&T 3600 (actually Olivetti M24) computer and a Seagate
harddisk (ST251-1) using a Western Digital Controller (WD1002S-WX1).
For optimum results I must set the interleave factor to 5, which
slows down the data transfer rate (disk<-->host) to appr. 100K per
second.
Other people I have spoken to, have informed me that they run with
an interleave factor of 3 (data transfer: 170K/s), on a "simple" ;-)
IBM XT at 4.77MHz.
I would think that my Olivetti (clock 8MHz) should be able to at 
least the same interleave(3)/transfer rate(170K/s), but for some 
reason it will not work properly.
My questions are:

    1. Is there someone out there who has the same problem?
    2. Is there someone with an AT&T 3600 with a data rate
       of 170K/s (and a corresponding interleave of 3)?
    3. Is there someone who can tell me where the problem
       originates and perhaps how to solve it?
