I have 2 of the drives, though not my mac, but on my pc, with a tekram
controller.
Docs can be found at:

jumpers: http://www.hitachigst.com/hdd/support/dghs/dghsjum.htm
Also using an 80 pin to 50 adapter.
I have 1 configured to delay power up, but configured the other to
power up
normally. Actually, I'd have both installed, but the drive is little
too tall to fit,
in the 3 1/4 in bay, so I have 1 in a using a rail kit, in 5 1/4" bay
from my dmesg:

I have disable sync set, dis- TI sync . as shipped the only jumpers
were
on 1 for id, 1 on autostart , and 1 on dis TI sync.
Sure your setting the right jumpers? and if there are jumpers on the
converter as well?
I think maybe the sense of autostart is reversed.
