Hi Dick
All three drives have the same problems. These are 306 cylinder 6 heads. I have
about 50 Dives but none with this head and cylinder count. So I don't really
know
if I really do need the correct controller yet or not. I do need a seagate ST
419
or similar drive though. I still would like a WD 1001 5.5. for 2 reasons. 1 to
keep the
Molecular original and 2 to help trouble shoot the other controller.
You should know that you can use a different ST-506/411 interface drive
instead of the failed models provided it has the same or more cylinders
and heads. You will only be able to utilize the 306/6 capacity unless
you revise some of the soft(firm?)ware, but it should provide a go/no-go
test of the controllers.
ST251 will work. Using part of these 820cyl x 6 heads x 17 sectors
as ST419 on that machine for trouble shooting job or any 6 or 8 heads
of ST505/412 interface also work.
