Hello Jeff,
from a posting of Claus Justus Heine to this list:
-----------------
The automatic data-rate reduction was broken with the internal Ditto
Max drives in 4.02. It stopped by 3000kbps instead of reducing the
rate further to 2000kbps in case of overrun errors. A priori reduction
using the "ft_fdc_rate_limit" module parameter was NOT affected by
this bug.
------------------
So might be you need a newer version of ftape.
Also: you should compile your kernel with _no_ ftape support - not even
with ftape support as modules.
Further, try to reduce the rate a priori, by setting:
insmod ftape-internal.o ft_fdc_rate_limit=2000
A further issue is, if your internal floppy controller is capable of
doing 2000kbps (kilobits per second, or 2Mbits/s).
Tim Jones from EST has got Ditto Max working with ftape 4.02, but, he
wrote to the list, you need at least a Pentium 166 MHz (no problem for
you) AND the Ditto DASH DX card to get at least a rate of 2000kbps.
Also: If your card is Plun&Pray, you will need the isapnp tool (i.e.
install the isapnp package) and configure your card with it.
I don't have such a drive myself, so I could give you only some hints.
Try with a new kernel without ftape support first, then the rest.
Regards
Chris
