I ran into similiar problems when I tried to install NetBSD-1.1
onto a machine with 2 old ESDI disks. It's some time ago know thus
I don't remember all the details. After placing some print-statements
in the kernel it turned out that the info the disk is giving about
itself is (IMHO) misinterpreted. There's one byte or word read from
disk which's bits are describing the features of the disk (ie. cts-
or lbn-adressing, etc.). If I remember correctly, then my disk returned
(-1) to this call which was interpreted as "all bits set".

But even after clearing all the bits the disk didn't work correctly
and I somehow lost interest in fiddling around with this stuff. Thus
I got rid of both ESDI disks without solving the problem...

This wont help you, but at least you know that you're not alone  :-)

Ciao,
