You probably do have the HDD plugged into the SE instead of the LVD connection,
I have the same controller/drive setup and it reports 80.0MB/s

You can set your kernel to have a shorter timeout delay.  I can't recall the
exact option, check the LINT kernel.  On the boot floppy kernel its 15 seconds,
and on the generic its 8 (I think) I adjusted it down to 4, and haven't had a
problem.
