Original question:

>After I installed 2.5 on it and do a 'cold boot', the external disk drive

Solution:
Almost everyone pointed out there's a jumper on the disk drive board
that will automatically spin up when power-on. I looked up the
disk manual and the factory default have it set to 'disable spin'.
So, I opened up the external 'lunchbox' cover and took the jumper
out, which is 'enable spin' (jumper 'E5' on a Conner 1.05GB disk drive).
Then, the ext. disk drive cold-booted up without any problem.
Thanks!!!
