The reason your 800k drive won't work on your old 512K is
that you need a copy of the Hard Disk 20 startup software. It's 
a single file called "Hard Disk 20". Put it on a normal disk, and
boot up with that disk. The system will then recognize your 
800K external drive.

You should try to find version 1.1 of this file, if you can. It's much
less buggy than version 1.0.

Note that your troubles come from a lack of proper software
and not because of any power-supply weaknesses.

Hope this helps...
